10% AHA BHA PHA Serum
10% AHA BHA PHA Serum
Product Description
Product overview
A concentrated triple-acid exfoliating serum combining 10% Glycolic Acid Complex with Lactic Acid (AHA), Salicylic Acid (BHA), and Gluconolactone (PHA) to gently resurface skin, unclog pores, brighten complexion, and refine texture — all while Panthenol and Aquaxyl keep skin hydrated and protected.
Triple Acid Exfoliation
Combines AHA (Lactic + Glycolic Acid), BHA (Salicylic Acid), and PHA (Gluconolactone) for multi-level exfoliation that targets surface texture, clogged pores, and dull skin simultaneously.
Texture & feel
SENSORYTriple Acid Exfoliation
Combines AHA (Lactic + Glycolic Acid), BHA (Salicylic Acid), and PHA (Gluconolactone) for multi-level exfoliation that targets surface texture, clogged pores, and dull skin simultaneously.
Brightening Vitamin C
3-O-Ethyl Ascorbic Acid is a stable form of Vitamin C that helps fade dark spots, even skin tone, and provide antioxidant protection against environmental damage.
Aquaxyl Hydration Complex
Patented trio of Xylitylglucoside, Anhydroxylitol, and Xylitol that boosts natural moisturizing factors and strengthens the skin barrier while exfoliating acids do their work.
Barrier-Friendly Formula
Panthenol (Pro-Vitamin B5) soothes and repairs the skin barrier while Niacinamide helps minimize pores and control oil — preventing the irritation often caused by acid-based products.
Safety & compatibility
SAFEContains Salicylic Acid (BHA), which most dermatologists recommend avoiding during pregnancy and breastfeeding. Glycolic and Lactic Acids at this concentration may also be too strong. Consult your doctor before use.
Contains PEG-9 Polydimethylsiloxyethyl Dimethicone (a PEG-modified silicone) and Polydextrose which may potentially feed Malassezia yeast in sensitive individuals. Patch test recommended if you are prone to fungal acne.
Clinically tested for safety on delicate skin. Formulated without harsh alcohols, common allergens, fragrances, oils, parabens, or sulfates.
Rated 1/5 on the comedogenic scale. Oil-free, lightweight formula is unlikely to clog pores. Key ingredients Panthenol and Glycerin have a comedogenic rating of 0.
AHA acids (Glycolic and Lactic Acid) increase photosensitivity. Daily sunscreen (SPF 30+) is mandatory when using this product, even on cloudy days.
Slight tingling or mild warmth upon application is normal with AHA/BHA products. Persistent burning, redness, or stinging is not — discontinue use and consult a dermatologist if this occurs.
Ingredient breakdown
INGREDIENTSGlycolic Acid Part of 10%Proven
The smallest AHA molecule, Glycolic Acid penetrates deepest for the most effective exfoliation. It dissolves the bonds between dead skin cells, stimulates collagen production, and boosts natural hyaluronic acid levels for smoother, firmer, brighter skin.
- Proven benefits: Exfoliation, collagen stimulation, skin brightening, improved texture
- Research: Extensive clinical data supporting anti-aging and resurfacing benefits at concentrations above 5%
Lactic Acid (AHA) Part of 10%Proven
A gentler AHA than Glycolic Acid with larger molecules for less irritation. Lactic Acid is also a natural component of the skin's own moisturizing system (NMF), so it exfoliates while simultaneously hydrating. It helps boost ceramide production for a stronger barrier.
- Dual action: Exfoliates surface dead skin cells while acting as a humectant
- Research: Shown to increase ceramide production and improve skin barrier function
Salicylic Acid (BHA) Up to 2%Proven
The gold-standard BHA for acne-prone skin. Unlike AHAs, Salicylic Acid is oil-soluble, which means it can penetrate into pores to dissolve sebum, blackheads, and whiteheads from within. It also has anti-inflammatory properties similar to aspirin.
- Oil-soluble: Penetrates deep into pores to unclog sebum and debris
- FDA-approved: Recognized at 0.5–2% for OTC acne treatment
Gluconolactone (PHA)Proven
A next-generation polyhydroxy acid (PHA) that exfoliates as effectively as traditional AHAs but with significantly less irritation thanks to its larger molecular size. It also acts as an antioxidant, a humectant, and helps repair the skin barrier — making it the gentlest acid in this formula.
- Gentle exfoliation: Larger molecules mean less penetration depth and less irritation
- Research: A 2004 study found Gluconolactone helps prevent UV damage without increasing sun sensitivity
3-O-Ethyl Ascorbic AcidPromising
A highly stable, water-soluble Vitamin C derivative known for superior skin-brightening ability. It resists oxidation far better than pure Vitamin C (L-Ascorbic Acid), maintains potency longer, and still offers antioxidant protection and potential collagen support.
- Stability: Resists oxidation and degradation, stays effective in formulation longer than pure Vitamin C
- Key benefit: Skin brightening and dark spot reduction
Panthenol (Pro-Vitamin B5)Proven
A powerful humectant and skin-soothing agent that calms irritation caused by exfoliating acids. Panthenol attracts and retains moisture, promotes lipid production for a stronger barrier, and has anti-inflammatory properties — the perfect counterbalance to active acids.
- Comedogenic rating: 0 — will not clog pores
- Research: Proven to increase skin hydration, reduce inflammation, and support barrier repair
Aquaxyl ComplexPromising
A patented trio of Xylitylglucoside, Anhydroxylitol, and Xylitol derived from plant sugars. This complex optimizes water reserves by boosting natural moisturizing factors (NMF) such as hyaluronic acid and chondroitin sulfate, while also increasing ceramide and cholesterol synthesis to prevent water loss.
- 3D hydration: Increases water content both instantly and long-term at just 3% concentration
- Barrier support: Boosts lipid synthesis including ceramides and cholesterol
Niacinamide (Vitamin B3)Proven
A well-researched multitasking ingredient that minimizes pores, controls oil, brightens skin, reduces redness, and strengthens the skin barrier. Works synergistically with acids to reduce irritation while amplifying brightening results.
- Multi-benefit: Pore minimizing, oil control, brightening, barrier support
- Synergy: Complements AHA/BHA by reducing inflammation and supporting barrier recovery

Where it fits in your routine
ROUTINEApply after cleansing and toning, before heavier serums or moisturizer. Use AM and PM for best results. Sunscreen is essential during the day.
How to use
HOW TO USECleanse Your Face
Start with a clean, dry face. Use a gentle cleanser to remove makeup, sunscreen, and impurities. Pat dry with a clean towel.
Dispense 2–3 Drops
Squeeze 2–3 drops of the serum onto your fingertips or directly onto your face. A little goes a long way with this concentrated formula.
Gently Pat & Spread
Pat the serum evenly across your entire face, avoiding the eye area and lips. Do not rub — gentle patting ensures even distribution and better absorption.
Follow with Moisturizer & SPF
Wait 30 seconds for full absorption, then apply your moisturizer. In the morning, always finish with a broad-spectrum sunscreen (SPF 30+) to protect freshly exfoliated skin.
Who is it for?
WHOPerfect for you if:
- You want smoother skin texture and refined pores
- You struggle with blackheads, whiteheads, or clogged pores
- You want a brighter, more even complexion
- You are new to chemical exfoliants and want a multi-acid formula at moderate strength
- You prefer fragrance-free, paraben-free skincare
- You want an affordable exfoliating serum under $10
Consider alternatives if:
- You are pregnant or breastfeeding (contains Salicylic Acid)
- You have very sensitive skin or active rosacea flare-ups
- You are already using strong retinoids or other AHA/BHA products daily
- You need a larger bottle size (this is only 15ml)
- You have a severely compromised skin barrier
Skin type compatibility
SKIN TYPESOil-free, lightweight formula absorbs instantly. BHA penetrates pores to dissolve excess sebum. Niacinamide helps control oil production throughout the day.
Salicylic Acid unclogs pores and reduces breakouts. Low comedogenic rating (1/5). Helps clear blackheads and whiteheads with consistent use.
Balances well across different face zones. AHAs brighten and smooth dry patches while BHA controls oil in the T-zone. Aquaxyl provides balanced hydration.
Lactic Acid doubles as a humectant, and Panthenol + Aquaxyl provide good hydration. However, you will need a richer moisturizer on top for dry skin types.
The PHA (Gluconolactone) component is gentle, but Glycolic Acid can irritate very sensitive skin. Start with every other day use and always patch test first.

Budget-friendly alternatives (dupes)
DUPESAlso a triple-acid serum (AHA+BHA+PHA) from K-beauty. Larger 50ml bottle with Tea Tree and Centella Asiatica for added soothing. Slightly gentler overall acid concentration but a very similar concept and target audience.
A glycolic acid toner rather than a serum. Contains only AHA (no BHA or PHA). Much larger 240ml bottle at a great price. Better for general resurfacing but lacks the pore-clearing BHA and gentle PHA components of Aiken.
A very gentle AHA/BHA toner with lower acid concentrations. Better suited for daily prep use rather than active exfoliation. Larger 150ml bottle. Lacks the PHA, Vitamin C, and Niacinamide found in the Aiken serum.

Frequently asked questions
FAQThis serum is generally not recommended during pregnancy or breastfeeding. It contains Salicylic Acid (BHA), which most dermatologists advise avoiding during pregnancy due to its systemic absorption potential. The Glycolic and Lactic Acid concentrations may also be considered too strong for use during this period. Always consult your OB-GYN or dermatologist before introducing any acid-based skincare product during pregnancy or breastfeeding.
This serum should be used with caution if you are prone to fungal acne. While it is free from oils, fatty acids, and polysorbates (common fungal acne triggers), it does contain PEG-9 Polydimethylsiloxyethyl Dimethicone and Polydextrose, which some fungal acne resources flag as potentially problematic. The acids themselves (AHA, BHA, PHA) can actually help manage fungal acne by exfoliating, but the overall formula is not fully verified as malassezia-safe. Patch test if uncertain.
Since this serum already contains AHA, BHA, PHA, and Vitamin C, you do not need additional exfoliants or vitamin C in the same routine. Using it alongside retinol is possible but should be done cautiously — alternate days (acids one night, retinol the next) to avoid over-exfoliation. If you already use a strong retinoid (like tretinoin), consult your dermatologist before adding this serum. Never layer multiple strong acid products in the same routine.
This serum is best suited for oily, combination, and acne-prone skin types. The oil-free, lightweight formula absorbs quickly without greasiness, while BHA (Salicylic Acid) excels at clearing clogged pores. It also works well for dry skin thanks to the humectant properties of Lactic Acid and the Aquaxyl complex, though a heavier moisturizer may be needed on top. Sensitive skin types should start with every-other-day use and patch test first.
Most users report smoother texture and a visible glow within the first 1–2 weeks. Blackhead and whitehead reduction typically becomes noticeable by weeks 2–3. Brighter, more even skin tone and faded dark spots usually appear around weeks 4–6 with consistent twice-daily use. Some mild purging (small breakouts as clogged impurities surface) may occur in the first week — this is normal and temporary.
Apply this serum as Step 3 in your routine: after cleansing (Step 1) and toning (Step 2), but before your moisturizer (Step 4) and sunscreen (Step 5). Dispense 2–3 drops and gently pat across the entire face, avoiding the eye and lip area. The serum can be used both morning and evening. Always follow with sunscreen during the day, as AHA acids increase sun sensitivity.
No, this serum has a very low comedogenic rating of 1 out of 5 and is unlikely to clog pores. It is oil-free, and the key hydrating ingredients (Panthenol, Glycerin) have comedogenic ratings of 0. In fact, the BHA (Salicylic Acid) in this formula actively works to unclog pores and dissolve sebum buildup. Dimethicone is present but is non-comedogenic and simply provides a smooth application feel.
The serum has a Period After Opening (PAO) of 12 months. However, the small 15ml bottle will typically be used up within 2–4 weeks with twice-daily application (2–3 drops per use), so shelf life is rarely a concern. Store in a cool, dry place away from direct sunlight and keep the cap tightly sealed to maintain the potency of the acids and Vitamin C derivative.
Verdict: The Aiken 10% AHA BHA PHA Serum delivers impressive multi-acid exfoliation at an unbeatable price point. Its triple-acid formula effectively smooths texture, unclogs pores, and brightens skin, with bonus Vitamin C and Niacinamide adding extra value. The main drawback is its tiny 15ml size, which can feel impractical for daily use. If you are looking for an affordable introduction to chemical exfoliants, or want a travel-sized acid serum that genuinely works, this is an excellent choice. Just remember your sunscreen.

Quick Product Notes
Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging «promises» it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.
We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.
Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.
EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
