The best aha bha serums are separated from harsh, overpromising formulas by one factor: controlled exfoliation that respects the skin barrier. Acid percentages matter, but balance often decides whether skin looks smoother or simply feels irritated.
The comparison that follows covers a wide range of exfoliating formats and strengths, making the differences easier to see at a glance. Keep reading for a clearer path through the acid-focused skincare aisle.
Key Takeaways
- Choose an AHA BHA serum with acid strength that matches your skin’s tolerance and exfoliation experience.
- Check whether the formula includes barrier-supporting ingredients, such as ceramides, panthenol, or hyaluronic acid.
- Match the product format to its intended frequency, since daily serums and rinse-off peels require different routines.
- Look for the specific acid types listed, because glycolic, lactic, and salicylic acids address different skincare concerns.
- Treat fragrance, essential oils, and high active concentrations as potential irritation factors, especially for sensitive skin.

Minimalist AHA BHA 10% Exfoliator
If you are new to chemical exfoliation, this 10% AHA BHA formula offers a straightforward starting point. The product is positioned as a mild daily exfoliator, with a focus on uneven tone and a brighter-looking complexion.
Its main advantage is the balance between exfoliating action and a less aggressive positioning, which may suit beginners who want help with dullness and rough texture. The limitation is that the listing does not identify the specific acids or their individual concentrations, so you cannot assess the formula’s exact acid balance from the available details.
- Brand:Minimalist
- Product Type:Exfoliating serum
- Size:1 fl oz / 30 ml
- Key Acids:AHA and BHA
- Skin Benefit:Uneven tone
- Usage:Daily
- Additional Feature:Mild exfoliating approach
- Additional Feature:Designed for women and men
- Additional Feature:Radiance-focused formula
-
Mad Hippie AHA BHA Milk Serum
A milky texture and Ceramide NP make this a sensible choice if exfoliation usually leaves your skin feeling tight. The formula combines glycolic, lactic, and salicylic acids, giving you both surface exfoliation and pore-focused support.
The acid blend covers several common concerns, including dullness, uneven texture, and clogged pores, while the ceramide adds a barrier-supportive element. Still, using multiple acids can be too active for highly reactive skin, particularly if you already use retinoids or other exfoliating products.
- Brand:Mad Hippie
- Product Type:Face serum
- Size:2 fl oz
- Key Acids:Glycolic, lactic, salicylic
- Skin Benefit:Texture and pore care
- Usage:Leave-on serum
- Additional Feature:Barrier-supportive ceramide
- Additional Feature:Combines AHA and BHA
- Additional Feature:Lightweight milk formulation
-
SOME BY MI Miracle AHA BHA Serum
This Korean skincare serum is geared toward pores, excess sebum, and blackheads, with centella ampoule ingredients aimed at a calmer skin feel. Its combination of AHA, BHA, and PHA offers three types of exfoliating support, while niacinamide adds tone and oil-balance appeal.
You may prefer this option if you want an exfoliating serum with soothing and brightening ingredients in the same formula. The “30 Days Miracle” name sets an ambitious expectation, and the product listing does not provide acid percentages, so the actual exfoliating strength is difficult to judge.
- Brand:SOME BY MI
- Product Type:Ampoule serum
- Size:1.69 fl oz / 50 ml
- Key Acids:AHA, BHA, PHA
- Skin Benefit:Pore and sebum care
- Usage:Daily serum
- Additional Feature:Korean skincare formula
- Additional Feature:Centella-based soothing focus
- Additional Feature:Niacinamide included
-
The Ordinary Exfoliate Hydrate Duo
This set pairs a high-strength AHA/BHA peel with a separate hyaluronic acid serum, making it useful if you want exfoliation and hydration in one package. The peel contains AHA 30% and BHA 2%, while the companion serum adds hyaluronic acid and vitamin B5.
The two-step format lets you keep hydration separate from the exfoliating treatment, which can make product layering easier to understand. The limitation is intensity: a 30% AHA peel is not the gentlest choice for beginners or sensitive skin, and it should not be treated like a daily serum.
- Brand:The Ordinary
- Product Type:Serum duo
- Size:1 fl oz each
- Key Acids:AHA 30%, BHA 2%
- Skin Benefit:Exfoliation and hydration
- Usage:Peel and hydrating serum
- Additional Feature:Hyaluronic Acid 2% serum
- Additional Feature:Vitamin B5 included
- Additional Feature:Two-product skincare set
-
The Ordinary AHA BHA 30% Peel
For experienced acid users seeking a stronger resurfacing step, this AHA 30% and BHA 2% peel is the most concentrated option in the group. It is designed to address dull-looking skin and uneven texture through a short, rinse-off treatment rather than everyday use.
The formula offers clearly stated concentrations, which helps you understand its intended strength before adding it to your routine. That same intensity is the main drawback, since sensitive, dry, or compromised skin may find this peel too aggressive.
- Brand:The Ordinary
- Product Type:Peeling solution
- Size:1 fl oz
- Key Acids:AHA 30%, BHA 2%
- Skin Benefit:Brighter-looking skin
- Usage:Rinse-off peel
- Additional Feature:Advanced exfoliating treatment
- Additional Feature:Targets uneven texture
- Additional Feature:Single-step peel format
-
COSRX AHA BHA Vitamin C Serum
This COSRX serum combines AHA, BHA, and vitamin C, giving it a broader brightening and texture-focused profile than a basic acid formula. Niacinamide adds another ingredient associated with tone support and the look of enlarged pores.
It may suit you if dullness, uneven tone, and early signs of visible aging are your main concerns, and you prefer a multi-benefit serum. The available listing does not disclose the acid types or percentages, so you have less information about exfoliating strength than with The Ordinary options.
- Brand:COSRX
- Product Type:Booster serum
- Size:1.01 fl oz
- Key Acids:AHA and BHA
- Skin Benefit:Brightening and pore care
- Usage:Face serum
- Additional Feature:Vitamin C included
- Additional Feature:Anti-aging positioning
- Additional Feature:Niacinamide formula
-
Good Molecules Overnight Exfoliating Treatment
An overnight treatment makes this a practical pick if you prefer applying exfoliating products in the evening and leaving them to work as part of your nighttime routine. The AHA and BHA combination is aimed at improving the look of dullness, uneven texture, and congested pores.
Its simple treatment format is easy to place into a routine, especially for people who want more than a daily cleanser can provide. The product listing does not identify the individual acids or their concentrations, and overnight leave-on exfoliation may require caution if your skin is easily irritated.
- Brand:Good Molecules
- Product Type:Exfoliating treatment
- Size:1 fl oz
- Key Acids:AHA and BHA
- Skin Benefit:Texture refinement
- Usage:Overnight
- Additional Feature:Nighttime skincare step
- Additional Feature:Leave-on treatment
- Additional Feature:Pore-focused exfoliation
-
uLOOK AHA BHA Exfoliating Serum
With glycolic acid and salicylic acid named directly, this serum takes a focused approach to surface texture and pore congestion. Glycolic acid addresses buildup on the skin’s surface, while salicylic acid is oil-soluble and commonly used for blemish-prone areas.
You may find it useful if you want a compact two-acid formula without a long list of additional actives. Its limitation is the lack of disclosed percentages, which makes it difficult to estimate whether the formula is mild enough for frequent use or better suited to a slower schedule.
- Brand:uLOOK_
- Product Type:Exfoliating serum
- Size:1.01 fl oz
- Key Acids:Glycolic and salicylic
- Skin Benefit:Texture and pore care
- Usage:Face serum
- Additional Feature:AHA and BHA combination
- Additional Feature:Lightweight serum format
- Additional Feature:Surface exfoliation focus
-
medicube Zero Pore Peptide Serum
This product is the outlier in the roundup because the listing highlights peptides and pore care, not AHA or BHA acids. It may appeal to you if the goal is a smoother-looking pore area with a peptide-focused routine rather than direct chemical exfoliation.
The peptide positioning gives it a gentler-sounding role beside stronger acid treatments, but the available title does not confirm any exfoliating acids, acid percentages, or specific pore-care ingredients. For a dedicated AHA BHA serum roundup, that missing information is a clear limitation.
- Brand:medicube
- Product Type:Peptide serum
- Key Acids:Not listed
- Skin Benefit:Pore care
- Usage:Face serum
- Additional Feature:Zero Pore product line
- Additional Feature:Peptide skincare focus
- Additional Feature:Lightweight serum positioning
-
Arencia Eraser Shot Glycolic Serum
This serum is aimed at pore care and texture refinement, with glycolic acid named as the main booster ingredient and AHA BHA support in the title. Its lightweight, daily-use positioning may work well for you if rough texture and visible pores are recurring concerns.
The formula has a clear exfoliating purpose and a convenient serum format, which makes it easier to add to a routine than a rinse-off peel. Still, the listing does not provide the glycolic, AHA, or BHA percentages, so daily use should be approached carefully, especially alongside other active products.
- Brand:Arencia
- Product Type:Exfoliating serum
- Size:1.01 fl oz / 30 ml
- Key Acids:Glycolic acid, AHA, BHA
- Skin Benefit:Pore and texture care
- Usage:Daily serum
- Additional Feature:Eraser Shot product line
- Additional Feature:Booster-style formula
- Additional Feature:Exfoliating face serum
Frequently Asked Questions
Should You Choose An AHA Or BHA Serum?
Choose BHA for clogged pores, blackheads, and excess oil, since salicylic acid can move into oil-lined pores. Choose an AHA for rough texture, dullness, or uneven surface tone. A blend can address several concerns, but it may also increase irritation. If you are new to chemical exfoliation, starting with one acid makes it easier to judge how your skin responds.
How Often Should You Use An AHA Or BHA Serum?
Start with once or twice weekly, applying a thin layer after cleansing and before moisturizer. Increase to every other night only if your skin remains calm and comfortable. Daily use is not automatically better. Peeling, burning, or persistent redness usually means you need less frequent application, a milder formula, or a break from exfoliating acids.
Can You Use AHA And BHA Together?
Yes, but combining them in one routine can be irritating, particularly with sensitive, dry, or acne-treated skin. Use a product specifically formulated with both acids, or alternate an AHA night with a BHA night. Avoid adding retinoids, benzoyl peroxide, or other exfoliants to the same evening until you know your routine is well tolerated. Keep the rest of the routine gentle and moisturizing.
Should You Apply Acid Serum Before Or After Moisturizer?
Apply the serum after cleansing and before moisturizer when using a standard water-based formula. Follow the product directions, since some formulas are designed for use on damp skin while others recommend completely dry skin. If irritation is a concern, apply moisturizer first as a buffer, then use a small amount of serum. Finish with another light layer of moisturizer if your skin feels dry.
Can You Use AHA Or BHA During Pregnancy?
Pregnancy skincare should be discussed with your doctor or midwife, especially if you plan to use stronger exfoliating products or several active ingredients. Topical salicylic acid is often treated differently from oral salicylates, but personal medical guidance still matters. Avoid applying acids over large areas or damaged skin without professional advice. During pregnancy and breastfeeding, a simple routine with gentle cleansing, moisturizer, and daily sunscreen is a sensible foundation.
