Introduction to AHAs and BHAs
Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are exfoliating acids derived from natural sources. Their main power lies in clearing away dead skin cells and stimulating cell turnover. Here’s a quick overview:
| Aspect | AHA (Alpha Hydroxy Acid) | BHA (Beta Hydroxy Acid) |
|---|---|---|
| Solubility | Water-soluble – works on skin’s surface | Oil-soluble – penetrates pores |
| Best For | Dry, sun-damaged, or sensitive skin | Oily, acne-prone, or congested skin |
| Common Acids | Glycolic, lactic, mandelic (fruit, milk origins) | Salicylic acid (from willow bark) |
| Main Benefits | Smoother skin, reduced fine lines, fading dark spots | Clearing pores, reducing blackheads and breakouts |
| Sun Sensitivity | Increases sun sensitivity (use sunscreen) | Lower risk, but sunscreen still advised |
Unique Properties of AHAs
- Work mainly on the skin’s surface
- Excellent for surface-level issues: rough texture, hyperpigmentation, fine lines
- Improve moisture retention, leading to plumper, hydrated skin
Unique Properties of BHAs
- Penetrate deep into oil glands and unclog pores
- Target acne, blackheads, and excess sebum
- Soothing, anti-inflammatory properties
The Science and Benefits of AHA & BHA
Chemical exfoliants are highly effective for:
- Removing dead skin: Freshens and brightens the complexion
- Reducing pores and blackheads: Especially BHAs, which dislodge pore-clogging oil
- Smoothing rough texture: Essential for a younger-looking, more even skin tone
- Addressing hyperpigmentation: AHAs accelerate cell turnover to fade dark marks
- Minimizing fine lines: Both stimulate collagen production and cell renewal
- Increasing hydration: AHAs help skin hold onto moisture better
The Research
- Studies confirm that regular AHA use improves overall skin texture, reduces the appearance of sun damage, and assists with even skin tone.
- BHA (salicylic acid) is proven to decrease the severity and number of acne lesions and is particularly effective against blackheads and whiteheads.
Both acids offer anti-aging benefits by stimulating collagen and elastin production, contributing to firmer, more youthful skin.
Who Should Use AHA and BHA Products?
Choosing between AHA and BHA depends on your skin type and goals. Some products even combine both for broader benefits:
- Dry or sun-damaged skin: Benefit most from AHAs (glycolic, lactic), which hydrate and smooth the surface
- Oily or combination skin: BHAs (salicylic acid) penetrate pores to manage excess oil and breakouts
- Sensitive or redness-prone: Opt for gentler acids (like lactic acid or low-strength salicylic acid) and start slowly
- Dullness and dark spots: Try a combination of AHA and BHA for comprehensive renewal
- Acne-prone skin: BHAs are top performers and help prevent new blemishes; higher concentrations may be best for persistent cases
- Mature or aging skin: Regular AHA use smooths fine lines and fades age spots
How to Choose the Best AHA/BHA Serum or Peel
Not all chemical exfoliants are created equal! Use these criteria:
- Concentration: For home use, AHAs are often 5–10%, BHAs up to 2%. Peels may be higher but should be used with caution.
- Formulation: Look for pH-balanced products (pH 3-4.5 for optimal performance; too high and they won’t work, too low and they may irritate).
- Inactive ingredients: Fragrance-free and minimal allergenic additives preferred for sensitive skin.
- Type: Serums offer daily exfoliation, while peels are more intense and used weekly or monthly.
- Packaging: Opaque, airtight bottles prolong acid potency.
- Reputable sources: Stick to trusted brands and dermatologist recommendations.
Comparing Common AHA/BHA Acids
| Acid Type | Best For | Notes |
|---|---|---|
| Glycolic (AHA) | Normal, sun-damaged, rough skin | Strongest AHA; may irritate sensitive skin |
| Lactic (AHA) | Dry, sensitive skin | More hydrating, gentler than glycolic |
| Mandelic (AHA) | Sensitive, breakout-prone skin | Larger molecule; less irritating |
| Salicylic (BHA) | Oily, acne-prone, congested skin | Penetrates pores; helps with blackheads, inflammation |
Best AHA & BHA Serums and Peels by Skin Type
Here are highly rated serums and peels backed by dermatologists and satisfied users. Note: product recommendations are based on common expert consensus and up-to-date ingredient science.
Best for Dry & Sensitive Skin
- Lactic Acid Serum (5–10%): Provides gentle exfoliation while boosting hydration. Examples: The Ordinary Lactic Acid 5% + HA, Sunday Riley Good Genes Lactic Acid Treatment.
- Mandelic Acid Serums: Mandelic is one of the mildest AHAs, ideal for redness-prone skin. Example: The Ordinary Mandelic Acid 10% + HA.
- Low-concentration BHA (0.5–1%): Great for sensitive but acne-prone skin. Example: Paula’s Choice Calm 1% BHA Lotion Exfoliant.
Best for Oily & Acne-Prone Skin
- Salicylic Acid Serum (2%): Unclogs pores and controls oil. Top picks: Paula’s Choice Skin Perfecting 2% BHA Liquid Exfoliant, Neutrogena Rapid Clear Maximum Strength Acne Medicine.
- AHA/BHA Combination Serums: Target multiple concerns. Examples: Drunk Elephant T.L.C. Framboos Glycolic Night Serum (contains glycolic, lactic, salicylic acids).
- BHA Peels: Weekly or bi-weekly, provide a deeper clean. Example: The Ordinary Salicylic Acid 2% Masque.
Best for Dull, Mature, or Sun-Damaged Skin
- Glycolic Acid Serum (7–10%): Renews skin and fades pigmentation. Examples: Pixi Glow Tonic (5% glycolic), The Ordinary Glycolic Acid 7% Toning Solution.
- AHA Peels (with glycolic/lactic/citric acids): Used 1-2x/week. Example: The Ordinary AHA 30% + BHA 2% Peeling Solution (use with caution, patch-test first).
- Professional-grade at-home peels: Only if your skin is accustomed to acids; Dermalogica Rapid Reveal Peel, Dr. Dennis Gross Alpha Beta Universal Daily Peel.
Best for Combination Skin
- Multi-acid Serums: Contain both AHAs and BHAs to target dry patches and oily T-zone. Examples: The Inkey List AHA + BHA Serum, Allies of Skin Mandelic Pigmentation Corrector Night Serum.
- Spot Treatments: For breakouts, try a dedicated 2% salicylic acid gel on affected areas. Example: ZitSticka Killa Kit.
How to Use AHA & BHA Safely for Best Results
To minimize risk and maximize benefits, follow these principles:
- Start slow: 2–3 times per week, increasing frequency as tolerated.
- Patch-test: Always test new acids on a small area before full-face application.
- Apply after cleansing, before heavier serums or moisturizers.
- Use sunscreen daily: Especially with AHAs, as they heighten photosensitivity.
- Don’t mix with strong actives (retinol, vitamin C, benzoyl peroxide) unless your skin is already tolerant.
- Listen to your skin: Redness, flaking, or irritation means reduce frequency or strength.
- Professional peels: Always seek guidance for high-strength acids (over 15% AHA, over 2% BHA).
If combining AHA and BHA, consider alternating days or using a dual-acid serum formulated for balance. Over-exfoliation leads to irritation, sensitivity, and barrier damage.
Frequently Asked Questions (FAQs)
What is the difference between an AHA peel and an AHA serum?
An AHA peel is a higher-concentration treatment meant for short, infrequent application (weekly or less), offering quick, dramatic exfoliation. An AHA serum is used daily or a few times per week, designed for ongoing gentle renewal and hydration.
Can I use AHA and BHA at the same time?
Yes, but only if your skin is accustomed. Products blending both are formulated for safe use, but if layering separate products, alternate days or spot-test first. Overuse can cause irritation.
Are AHA and BHA safe for sensitive skin?
Yes, if you choose gentler acids/low concentrations and introduce them slowly. Lactic and mandelic acid (AHA), or low-dose salicylic acid (BHA) are the most tolerable options. Always patch-test first.
How long before I see results with AHA/BHA?
You may notice smoother, brighter skin within a week. For stubborn issues (acne, pigmentation, fine lines), visible results typically take 4–8 weeks of consistent, proper use.
Can I use AHA/BHA if I have active acne?
Yes. BHAs are highly recommended for treating and preventing acne, while AHAs address discoloration and textural scars. Use as directed, start slowly, and support with non-comedogenic moisturizers.
Do I really need to wear sunscreen if I use acids?
Absolutely. Both AHAs and BHAs increase sun sensitivity and the risk of sun damage. Daily SPF 30+ is essential for safety and to maintain improvements.
Are there any risks or side effects?
Main risks are redness, peeling, increased sensitivity, and post-inflammatory hyperpigmentation if misused, especially with stronger peels or dark skin. Always follow instruction and hydrate/protect your skin to minimize adverse reactions.
Expert Tips for Maximizing Exfoliation Benefits
- Hydrate deeply: Follow acids with gentle hydration (like hyaluronic acid, ceramides) to strengthen your barrier.
- Don’t mix too many exfoliants: You can overdo it—balance with calming, nourishing products alongside acids.
- Adjust with the seasons: Drier weather or increased sun exposure means you may need to reduce exfoliation frequency.
- See a professional: For stubborn concerns (like severe acne or pigmentation), ask a dermatologist about prescription-strength peel options or in-office treatments.
