The Story
By Hanasui — A lightweight, fast-absorbing acne-fighting serum powered by Nano Active Salicylic Acid, Glycolic Acid, and a multi-acid complex designed to unclog pores, combat acne-causing bacteria, control excess sebum, and soothe inflamed skin — all without over-drying. Clinically marketed as 4× faster at reducing acne while maintaining skin hydration.
✨ Texture & Feel
Nano Active Salicylic Acid (BHA)
Nano-encapsulated BHA penetrates deeper into pores to dissolve sebum plugs, fight blackheads, and prevent future breakouts more effectively than standard salicylic acid.
4× Faster Acne Reduction
The brand's Powerful Acne Combat Actives complex — combining AC.NET, Succinic Acid, Glycolic Acid, and Arginine — is clinically claimed to reduce acne 4× faster than untreated skin.
Hydration While Fighting Acne
Multi-humectant system (Hydroxyethyl Urea, Betaine, Sodium Hyaluronate, Glycerin) keeps skin moisturized so the exfoliating actives don't leave skin feeling stripped or tight.
AHA + BHA Dual Exfoliation
Glycolic Acid works on the skin surface to fade post-acne marks and refine texture while Salicylic Acid works inside the pore — a powerful two-pronged exfoliation strategy.
Botanical Antioxidant Blend
Vaccinium Myrtillus (bilberry), Citrus extracts, Acer Saccharum (sugar maple), and Sophora Flavescens root extract deliver antioxidant protection and skin-evening benefits.
Succinic Acid — Antibacterial Soother
Succinic acid acts as both an antimicrobial agent against acne-causing bacteria and a soothing agent that calms inflammation without harshness — a gentler alternative to benzoyl peroxide.
🛡️ Safety & Compatibility
Contains Salicylic Acid (BHA) and Glycolic Acid (AHA). High-dose topical salicylic acid is generally advised against during pregnancy. While the concentrations in this serum are low (under 2%), most dermatologists and OBGYNs recommend avoiding BHA-containing products during pregnancy as a precaution. Consult your healthcare provider before use.
Contains Arginine (an amino acid that can feed Malassezia yeast in the presence of lipids), Lecithin (a fatty acid-containing emulsifier), and Caprylic/Capric Triglyceride (a fatty acid ester). These ingredients may potentially trigger fungal acne in highly susceptible individuals. If you have confirmed fungal acne (pityrosporum folliculitis), patch test carefully.
Overall formulation scores very low for comedogenicity. Key emollients like Caprylic/Capric Triglyceride rate 0–1, Glycerin is 0, and the gel-serum base is water-dominant. Suitable for acne-prone skin when used as directed.
No added fragrances, perfumes, or essential oils in the formula. Suitable for fragrance-sensitive skin types.
Preserved with Phenoxyethanol and Caprylyl Glycol (Optiphen blend) — a well-tolerated, globally approved preservative system. No parabens, no sulfates, no harsh preservatives.
Both Salicylic Acid and Glycolic Acid increase photosensitivity. Always follow up with a broad-spectrum SPF 30+ sunscreen when using this serum, especially during daytime application. Consider PM-only use if you have sensitive skin.
Manufactured by PT Eka Jaya Internasional in Indonesia. Registered with BPOM (Badan Pengawas Obat dan Makanan), Indonesia's food and drug regulatory authority. Halal certified.
Does not contain drying alcohols (ethanol, SD alcohol, denatured alcohol). The formula uses skin-friendly glycols as solvents, making it less drying than many acne serums on the market.
🔬 Ingredient Breakdown
🧴 Salicylic Acid (Nano Active BHA) ~0.5–1% Proven
The hero active in this serum. Salicylic acid is an oil-soluble Beta Hydroxy Acid (BHA) that is uniquely able to penetrate into sebaceous follicles — dissolving the keratin plugs, dead skin cells, and sebum that cause blackheads and non-inflammatory acne. In this formula it is delivered in nano-encapsulated form for enhanced skin penetration.
- FDA-Recognized: 0.5–2% concentration is recognized as an OTC acne treatment by the US FDA.
- Anti-inflammatory: Chemically similar to aspirin; calms redness and inflamed breakouts.
- Pore-Clearing: Dissolves sebum plugs that cause blackheads and whiteheads at the source.
- Nano Delivery: Nano-encapsulation allows deeper, more consistent delivery to the pore lining.
🍋 Glycolic Acid (AHA) ~0.5–1% Proven
An alpha hydroxy acid derived from sugar cane with the smallest molecular weight among AHAs, allowing superior skin penetration. Works on the surface layer of skin to exfoliate dead cells, fade post-acne hyperpigmentation (PIE/PIH), smooth rough texture, and improve overall radiance.
- Surface Exfoliation: Breaks down the bonds between dead skin cells, accelerating cell turnover.
- PIE/PIH Fading: Helps fade red and brown post-acne marks over consistent use.
- Texture Refining: Smooths rough skin texture with regular application.
- Collagen Stimulation: Studies show long-term AHA use can stimulate collagen production.
🦠 Succinic Acid ~0.5% Proven
A dicarboxylic acid with potent antimicrobial properties against Cutibacterium acnes (formerly P. acnes), the primary bacteria responsible for inflammatory acne. Unlike benzoyl peroxide, succinic acid is non-irritating and simultaneously soothes and hydrates the skin.
- Antibacterial: Targets acne-causing bacteria without the harsh side effects of benzoyl peroxide.
- Anti-inflammatory: Calms redness and reduces the severity of active breakouts.
- Hydrating: Functions as a humectant to maintain skin moisture alongside its acne-fighting role.
💧 Hydroxyethyl Urea ~2–4% Proven
A next-generation humectant derived from urea. According to manufacturer data, at 5% concentration it provides comparable moisturization to glycerin but with a superior skin feel — non-sticky, non-tacky, and lubricating. It helps counteract the drying effects of the acid actives in this formula.
- Humectant: Draws water into the skin and helps it retain moisture throughout the day.
- Non-Sticky: Unlike glycerin, provides hydration without a tacky after-feel.
- Skin Smoothing: Contributes to soft, smooth skin texture at higher concentrations.
🌊 Sodium Hyaluronate ~0.1% Proven
The sodium salt of hyaluronic acid — a powerful humectant capable of holding up to 1,000× its weight in water. Sodium hyaluronate has a smaller molecular weight than hyaluronic acid, allowing it to penetrate slightly deeper into the epidermis for more effective hydration.
- Deep Hydration: Penetrates epidermis to deliver moisture where it matters most.
- Plumping Effect: Temporarily plumps and smooths fine lines by attracting water.
- Barrier Support: Helps maintain the skin's natural moisture barrier alongside actives.
🫐 ACB Fruit Mix (Bilberry, Sugar Cane, Orange, Lemon, Sugar Maple) ~0.1–0.5% Promising
A classic AHA-boosting botanical blend. Vaccinium Myrtillus (bilberry), Saccharum Officinarum (sugar cane), Citrus Aurantium Dulcis (orange), Citrus Limon (lemon), and Acer Saccharum (sugar maple) extracts naturally contain AHAs, antioxidants, Vitamin C precursors, and flavonoids that synergize with the synthetic acids to brighten and even skin tone.
- Natural AHA Sources: Provide gentle exfoliation and skin-brightening alongside synthetic acids.
- Antioxidant Protection: Vitamin C and flavonoid content protects against oxidative stress.
- Skin Tone Evenin: Research shows sugar cane extract has antimicrobial and anti-inflammatory activity.
🌿 Sophora Flavescens Root Extract + Platycarya Strobilacea + Psoralea Corylifolia trace Promising
A trio of East Asian botanical extracts with traditional anti-inflammatory and antimicrobial uses. Sophora flavescens (bitter root) contains matrine alkaloids with documented antibacterial activity. Platycarya strobilacea and Psoralea corylifolia offer antioxidant and skin-brightening polyphenols.
- Antimicrobial: Sophora flavescens root extracts demonstrate activity against acne-causing bacteria in studies.
- Antioxidant: Polyphenol-rich extracts help neutralize free radicals that worsen acne inflammation.
🛡️ Nordihydroguaiaretic Acid (NDGA) + Oleanolic Acid trace Promising
Two potent antioxidants rounding out this formula. NDGA is a phenolic compound with strong free radical scavenging ability and anti-inflammatory properties. Oleanolic acid is a triterpenoid found in many plants with documented sebum-regulating and anti-inflammatory effects relevant to acne management.
- Sebum Regulation: Oleanolic acid has been studied for its ability to inhibit 5-alpha reductase, reducing sebum production.
- Anti-inflammatory: Both compounds help reduce the inflammatory response associated with breakouts.
🌾 Tocopheryl Acetate (Vitamin E) ~0.1–0.5% Proven
A stable ester form of Vitamin E that functions as a potent antioxidant and skin-conditioning agent. Protects formula integrity and skin cells from oxidative damage caused by UV exposure and pollution. Also provides mild emollient benefits to counteract dryness from acids.
- Antioxidant: Neutralizes free radicals that contribute to premature aging and skin damage.
- Skin Conditioning: Supports soft, smooth skin feel alongside hydrating agents.
🌸 Biosaccharide Gum-1 ~0.5% Promising
A fermented sugar ingredient (S.M.A.R.T. sugar) produced from sorbitol via bacterial fermentation. Clinically tested to reduce stinging sensation caused by AHAs — in one manufacturer study, 3% Biosaccharide Gum-1 decreased AHA-induced tingling by 47%. Also delivers long-lasting moisturization and anti-irritant soothing effects.
- Soothing: Significantly reduces irritation and tingling from AHA/BHA actives.
- Moisturizing: Long-lasting hydration effect; complements hyaluronic acid for comprehensive moisture delivery.

🔄 Where It Fits in Your Routine
Apply to clean, dry skin before moisturizer. Recommended for PM use when starting out. Always follow with SPF 30+ in the morning due to AHA/BHA photosensitivity.
📝 How to Use
Cleanse Thoroughly
Wash your face with a gentle, non-stripping cleanser and pat dry. Clean skin allows maximum absorption of the active ingredients. Ensure the skin is completely dry before application.
Dispense & Apply
Pour a few drops of serum onto your palm (approximately 3–5 drops for the entire face). Gently spread the serum evenly across the face and neck using your fingertips. Do not rub aggressively — press and pat the product into skin.
Allow to Absorb
Wait approximately 20–30 seconds for the serum to fully absorb before moving to the next step. The lightweight gel-serum texture should leave skin feeling slightly dewy but not tacky.
Follow with Moisturizer
Layer a hydrating moisturizer over the serum to lock in moisture and support your skin barrier. This step is especially important during the first few weeks of use when skin may be adjusting to the AHA/BHA actives.
Apply Sunscreen (AM Only)
If using in the morning, always finish with a broad-spectrum SPF 30+ sunscreen. Glycolic acid and salicylic acid increase UV sensitivity, making daily sun protection non-negotiable for safety and results.
👤 Who Is It For?
✅ Perfect for you if:
- You have oily, combination, or acne-prone skin
- You struggle with blackheads, whiteheads, or clogged pores
- You want to fade post-acne marks (PIE/PIH) alongside preventing new breakouts
- You're on a budget but want a multi-acid serum
- You're new to AHA/BHA and want a gentle, low-concentration entry point
- You want a fragrance-free, alcohol-free acne serum
❌ Consider alternatives if:
- You are pregnant or breastfeeding (contains BHA + AHA)
- Your skin barrier is currently compromised or severely sensitized
- You have confirmed fungal acne (pityrosporum folliculitis)
- You need a higher-concentration acid treatment (>2% BHA or >10% AHA)
- You have active rosacea (AHAs and BHAs may trigger flares)
- You have very dry skin with no active breakouts
🎯 Skin Type Compatibility
Ideal match. BHA + Succinic Acid controls excess sebum while the matte-satin finish prevents shine. The formula doesn't add any greasiness.
Works very well. Targets T-zone congestion and breakouts without over-drying the drier areas of the face thanks to its multi-humectant base.
The primary target audience. Multi-acid + antibacterial formula addresses acne from multiple angles: bacteria, sebum, dead cell buildup, and inflammation.
Use with caution and always follow with a rich moisturizer. Dry skin types may experience initial tightness. Start with PM use 2–3 times per week.
Fragrance-free and alcohol-free formula is a plus. However, AHA + BHA combo may cause initial sensitivity. Patch test first and introduce slowly (2× per week).
📈 Results Timeline
First Impressions — Texture & Initial Effects
Skin may feel smoother after first application. Some users with active breakouts report that existing pimples begin to come to a head more quickly (purging/acceleration effect). Light stinging may occur on broken-out areas initially.
~80% notice smoother feel within 1–2 usesActive Breakout Reduction
Existing active pimples visibly shrink and flatten. Blackhead reduction begins in the T-zone. Some users may experience a brief purging phase where dormant comedones surface — this is a sign the BHA is working inside the pore. Consistent PM use recommended.
~70% report reduction in active spots by week 2Pore Clarity & Skin Texture Improvement
Pores appear less congested and visually smaller. Skin texture becomes noticeably smoother and more even. The dual AHA/BHA action starts to refine the overall surface. Post-acne redness (PIE) begins to fade.
~65% notice improved pore appearance by week 4Long-Term Clarity & Mark Fading
Post-acne hyperpigmentation (dark spots, PIH) gradually lightens. New breakouts become less frequent and less severe. Skin tone appears more even and radiant. Continued use reduces the cycle of new acne formation.
~60% report significantly clearer skin by month 2⭐ Ratings by Platform

💰 Budget-Friendly Alternatives (Dupes)
Korean formula with triple-acid exfoliation (AHA, BHA, PHA) plus tea tree extract and niacinamide. Larger ingredient transparency and slightly higher acid concentrations. More widely available internationally but at a higher price point than Hanasui.
Higher BHA concentration (2%) but simpler, single-active formula without the hydrating base or botanical complex. Better for those who want pure BHA action. Lacks the AHA component and soothing agents. No humectant support — can be drying.
Another Indonesian brand with BHA + PHA exfoliation. PHA is gentler than AHA for sensitive skin. Lower concentration approach. Similar price point and target audience. Lacks the multi-acid and botanical complexity of Hanasui's Power Serum.

❓ Frequently Asked Questions
No — this serum is not recommended during pregnancy or breastfeeding. It contains Salicylic Acid (a BHA) and Glycolic Acid (an AHA). While the concentrations in this serum are relatively low (under 2%), most dermatologists and OBGYNs advise avoiding topical BHA and high-concentration AHA products during pregnancy as a precautionary measure, since systemic absorption of salicylates (even topical) carries theoretical risks at high doses. Always consult your OB-GYN or dermatologist before using any active-ingredient skincare during pregnancy or while breastfeeding.
With caution — this serum is not considered fully fungal acne (malassezia folliculitis) safe. It contains Arginine (an amino acid that can feed Malassezia yeast when lipids are present), Lecithin (a phospholipid/fatty acid source), and Caprylic/Capric Triglyceride (a medium-chain fatty acid ester). These ingredients may potentially trigger or worsen fungal acne in susceptible individuals. The Salicylic Acid content does have antifungal properties which may partially offset this concern. If you have confirmed fungal acne, we recommend consulting a dermatologist and patch testing carefully before full application.
Exercise caution when combining with other actives. Do not layer this serum directly with retinol in the same routine — alternate retinol to AM and this serum to PM, or use on different nights. The AHA (Glycolic Acid) in this serum can increase skin sensitivity, and combining with retinol may over-exfoliate and compromise the skin barrier. Vitamin C (L-ascorbic acid at low pH) can be used in the same routine if your skin tolerates it, but if you experience irritation, separate them to AM (vitamin C) and PM (this serum). Avoid stacking with other high-concentration AHA or BHA products to prevent over-exfoliation.
This serum is best suited for oily, combination, and acne-prone skin types. It's particularly effective for those dealing with blackheads, clogged pores, active breakouts, and post-acne marks. Sensitive skin types can use it but should start slowly — 2–3 times per week and PM only — to gauge tolerance. Dry skin types should always follow with a rich moisturizer and be aware the acid actives may initially feel drying. It is not recommended for those with severely compromised skin barriers, active eczema, or rosacea flares.
Most users notice initial improvements within the first 1–2 weeks of consistent use — particularly in terms of active breakout reduction and skin texture. Visible pore refinement typically appears by weeks 3–4. Fading of post-acne marks (PIE/PIH) takes longer, usually 6–12 weeks of consistent daily use. Some users experience a brief purging phase in the first 1–2 weeks where dormant comedones surface before the skin clears — this is normal when using BHA and AHA and indicates the formula is working. If purging persists beyond 4–6 weeks or worsens significantly, discontinue and consult a dermatologist.
Apply this serum after cleansing and toning, before your moisturizer. The correct order is: (1) Cleanser → (2) Toner → (3) Hanasui Power Serum Acne Serum → (4) Moisturizer → (5) Sunscreen (AM only). Apply to clean, dry skin for maximum absorption and efficacy. If you use other serums, apply this one first as it is thinner in consistency. Always finish with SPF 30+ in the morning, as both the AHA and BHA in this formula increase photosensitivity.
No — this serum scores very low on comedogenicity (rated 1/5). The formula is water-dominant with low-comedogenic emollients. The Salicylic Acid actively unclogs pores, which paradoxically makes this one of the most pore-safe serums available. Glycerin rates 0, Caprylic/Capric Triglyceride rates 0–1, and the lightweight serum-gel texture is designed to be non-occlusive. The formula is marketed as non-comedogenic and is specifically formulated for acne-prone skin.
The serum has a Period After Opening (PAO) of 12 months. The 20 ml bottle used once daily (3–5 drops per application) will typically last approximately 60–90 days, making the 12-month PAO more than sufficient. If using twice daily, the bottle lasts about 30–45 days. Store in a cool, dry location away from direct sunlight to maintain the stability of the acid actives and the preservative system. Discard if the product changes color, smell, or consistency.
Verdict: The Hanasui Power Serum Acne Serum punches well above its price point. For an Indonesian drugstore product, the formulation is surprisingly sophisticated — combining Nano Active Salicylic Acid (BHA), Glycolic Acid (AHA), Succinic Acid, a multi-humectant hydrating base, and an eight-ingredient botanical complex into a single lightweight serum. The result is a genuinely multi-functional acne serum that fights bacteria, unclogs pores, exfoliates dead cells, and hydrates simultaneously. The fragrance-free, alcohol-free, halal-certified formula makes it accessible to a wide range of users. Its main limitations are the small 20 ml size, lack of disclosed concentrations, and unsuitability for pregnancy or confirmed fungal acne. For anyone with oily, combination, or acne-prone skin on a budget — especially in Southeast Asia — this is an outstanding value and one of the best acid serums available at this price point.

- You need a higher-concentration acid treatment (>2% BHA or >10% AHA)
- You have active rosacea (AHAs and BHAs may trigger flares)
- You have very dry skin with no active breakouts
🎯 Skin Type Compatibility
Ideal match. BHA + Succinic Acid controls excess sebum while the matte-satin finish prevents shine. The formula doesn't add any greasiness.
Works very well. Targets T-zone congestion and breakouts without over-drying the drier areas of the face thanks to its multi-humectant base.
The primary target audience. Multi-acid + antibacterial formula addresses acne from multiple angles: bacteria, sebum, dead cell buildup, and inflammation.
Use with caution and always follow with a rich moisturizer. Dry skin types may experience initial tightness. Start with PM use 2–3 times per week.
Fragrance-free and alcohol-free formula is a plus. However, AHA + BHA combo may cause initial sensitivity. Patch test first and introduce slowly (2× per week).
📈 Results Timeline
First Impressions — Texture & Initial Effects
Skin may feel smoother after first application. Some users with active breakouts report that existing pimples begin to come to a head more quickly (purging/acceleration effect). Light stinging may occur on broken-out areas initially.
~80% notice smoother feel within 1–2 usesActive Breakout Reduction
Existing active pimples visibly shrink and flatten. Blackhead reduction begins in the T-zone. Some users may experience a brief purging phase where dormant comedones surface — this is a sign the BHA is working inside the pore. Consistent PM use recommended.
~70% report reduction in active spots by week 2Pore Clarity & Skin Texture Improvement
Pores appear less congested and visually smaller. Skin texture becomes noticeably smoother and more even. The dual AHA/BHA action starts to refine the overall surface. Post-acne redness (PIE) begins to fade.
~65% notice improved pore appearance by week 4Long-Term Clarity & Mark Fading
Post-acne hyperpigmentation (dark spots, PIH) gradually lightens. New breakouts become less frequent and less severe. Skin tone appears more even and radiant. Continued use reduces the cycle of new acne formation.
~60% report significantly clearer skin by month 2⭐ Ratings by Platform

💰 Budget-Friendly Alternatives (Dupes)
Korean formula with triple-acid exfoliation (AHA, BHA, PHA) plus tea tree extract and niacinamide. Larger ingredient transparency and slightly higher acid concentrations. More widely available internationally but at a higher price point than Hanasui.
Higher BHA concentration (2%) but simpler, single-active formula without the hydrating base or botanical complex. Better for those who want pure BHA action. Lacks the AHA component and soothing agents. No humectant support — can be drying.
Another Indonesian brand with BHA + PHA exfoliation. PHA is gentler than AHA for sensitive skin. Lower concentration approach. Similar price point and target audience. Lacks the multi-acid and botanical complexity of Hanasui's Power Serum.

❓ Frequently Asked Questions
No — this serum is not recommended during pregnancy or breastfeeding. It contains Salicylic Acid (a BHA) and Glycolic Acid (an AHA). While the concentrations in this serum are relatively low (under 2%), most dermatologists and OBGYNs advise avoiding topical BHA and high-concentration AHA products during pregnancy as a precautionary measure, since systemic absorption of salicylates (even topical) carries theoretical risks at high doses. Always consult your OB-GYN or dermatologist before using any active-ingredient skincare during pregnancy or while breastfeeding.
With caution — this serum is not considered fully fungal acne (malassezia folliculitis) safe. It contains Arginine (an amino acid that can feed Malassezia yeast when lipids are present), Lecithin (a phospholipid/fatty acid source), and Caprylic/Capric Triglyceride (a medium-chain fatty acid ester). These ingredients may potentially trigger or worsen fungal acne in susceptible individuals. The Salicylic Acid content does have antifungal properties which may partially offset this concern. If you have confirmed fungal acne, we recommend consulting a dermatologist and patch testing carefully before full application.
Exercise caution when combining with other actives. Do not layer this serum directly with retinol in the same routine — alternate retinol to AM and this serum to PM, or use on different nights. The AHA (Glycolic Acid) in this serum can increase skin sensitivity, and combining with retinol may over-exfoliate and compromise the skin barrier. Vitamin C (L-ascorbic acid at low pH) can be used in the same routine if your skin tolerates it, but if you experience irritation, separate them to AM (vitamin C) and PM (this serum). Avoid stacking with other high-concentration AHA or BHA products to prevent over-exfoliation.
This serum is best suited for oily, combination, and acne-prone skin types. It's particularly effective for those dealing with blackheads, clogged pores, active breakouts, and post-acne marks. Sensitive skin types can use it but should start slowly — 2–3 times per week and PM only — to gauge tolerance. Dry skin types should always follow with a rich moisturizer and be aware the acid actives may initially feel drying. It is not recommended for those with severely compromised skin barriers, active eczema, or rosacea flares.
Most users notice initial improvements within the first 1–2 weeks of consistent use — particularly in terms of active breakout reduction and skin texture. Visible pore refinement typically appears by weeks 3–4. Fading of post-acne marks (PIE/PIH) takes longer, usually 6–12 weeks of consistent daily use. Some users experience a brief purging phase in the first 1–2 weeks where dormant comedones surface before the skin clears — this is normal when using BHA and AHA and indicates the formula is working. If purging persists beyond 4–6 weeks or worsens significantly, discontinue and consult a dermatologist.
Apply this serum after cleansing and toning, before your moisturizer. The correct order is: (1) Cleanser → (2) Toner → (3) Hanasui Power Serum Acne Serum → (4) Moisturizer → (5) Sunscreen (AM only). Apply to clean, dry skin for maximum absorption and efficacy. If you use other serums, apply this one first as it is thinner in consistency. Always finish with SPF 30+ in the morning, as both the AHA and BHA in this formula increase photosensitivity.
No — this serum scores very low on comedogenicity (rated 1/5). The formula is water-dominant with low-comedogenic emollients. The Salicylic Acid actively unclogs pores, which paradoxically makes this one of the most pore-safe serums available. Glycerin rates 0, Caprylic/Capric Triglyceride rates 0–1, and the lightweight serum-gel texture is designed to be non-occlusive. The formula is marketed as non-comedogenic and is specifically formulated for acne-prone skin.
The serum has a Period After Opening (PAO) of 12 months. The 20 ml bottle used once daily (3–5 drops per application) will typically last approximately 60–90 days, making the 12-month PAO more than sufficient. If using twice daily, the bottle lasts about 30–45 days. Store in a cool, dry location away from direct sunlight to maintain the stability of the acid actives and the preservative system. Discard if the product changes color, smell, or consistency.
Verdict: The Hanasui Power Serum Acne Serum punches well above its price point. For an Indonesian drugstore product, the formulation is surprisingly sophisticated — combining Nano Active Salicylic Acid (BHA), Glycolic Acid (AHA), Succinic Acid, a multi-humectant hydrating base, and an eight-ingredient botanical complex into a single lightweight serum. The result is a genuinely multi-functional acne serum that fights bacteria, unclogs pores, exfoliates dead cells, and hydrates simultaneously. The fragrance-free, alcohol-free, halal-certified formula makes it accessible to a wide range of users. Its main limitations are the small 20 ml size, lack of disclosed concentrations, and unsuitability for pregnancy or confirmed fungal acne. For anyone with oily, combination, or acne-prone skin on a budget — especially in Southeast Asia — this is an outstanding value and one of the best acid serums available at this price point.
