AHA vs. BHA
Your Practical Guide to Chemical Exfoliation
Skincare can feel overwhelming sometimes, right? You’re scrolling through X, seeing folks rave about AHAs and BHAs, and thinking, “Which one do I need?” I’ve been there—staring at my skin, wishing it would just cooperate. Alpha Hydroxy Acids (AHA) and Beta Hydroxy Acids (BHA) are skincare superstars, but they’re not one-size-fits-all. Let’s break it down, section by section, with tips you can actually put to use, in a voice that feels like we’re chatting over a smoothie.
What Are AHA and BHA?
Picture your skin like a house. The paint (dead skin cells) starts flaking, and the pipes (pores) get clogged. AHAs and BHAs are your renovation team, but they handle different tasks. AHAs, like glycolic or lactic acid, are water-soluble and exfoliate the surface, leaving it smooth and radiant. BHAs, typically salicylic acid, are oil-soluble, diving into pores to clear out oil and gunk.
If your skin feels rough or looks dull, AHA’s your surface smoother. If blackheads or breakouts are the issue, BHA’s your pore-cleaning champ. Not sure? Glance at your T-zone—if it’s oily, start with BHA; if it’s dry or flaky, try AHA.
Now that we’ve got the basics, let’s figure out who these exfoliants are best for.

Who Should Use AHA or BHA?
Not every exfoliant suits every skin type, and picking the wrong one can leave you red-faced (literally)

Here’s the scoop:
AHAs slough off dead cells, boost turnover, and hydrate (lactic acid pulls in moisture). My dry cheeks glow after a 7% glycolic toner.
If you have very sensitive skin or active acne, AHAs might sting or inflame.
Salicylic acid clears pores, cuts oil, and soothes redness. A 2% BHA liquid saved my chin during my breakout years.
Who to avoid: Very dry or sensitive skin might find BHA too drying.
Take a selfie in natural light to check your skin. Shiny T-zone or pimples? Go BHA. Dull or flaky areas? AHA’s your pick. If you’ve got a mix, we’ll cover combining them soon.

How to Use AHA and BHA Safely
Chemical exfoliants aren’t complicated, but overdoing it is a real risk. Here’s how to start smart:
You’re using them right—awesome! But can you mix AHA and BHA, or is that a recipe for disaster?
Chemical exfoliants aren’t complicated, but overdoing it is a real risk. Here’s how to start smart:
- Patch Test: Dab a bit on your inner arm or behind your ear. Wait 24 hours. No irritation? You’re clear to proceed.
- Ease In: Use 2-3 times a week at night (both make your skin sun-sensitive). Stick to low concentrations—5-10% for AHA, 1-2% for BHA.
- Apply Correctly: After cleansing, apply to dry skin (toner, gel, or serum). Wait 5-10 minutes, then moisturize to seal in hydration.
- Sunscreen Is a Must: AHAs and BHAs increase sun sensitivity. Use SPF 30+ every morning, or you’re asking for trouble.
- Expect Purging: BHA might cause temporary breakouts as pores clear. Give it 4-6 weeks to shine.

Can You Use AHA and BHA Together?
If you’ve got combination skin (oily T-zone, dry cheeks) or multiple issues (acne and dullness), you might want both. Good news: you can combine AHA and BHA, but it’s like mixing spices—go easy.
AHA and BHA are like the power couple of skincare, each with their own strengths. AHA’s your glow-up buddy for dry or dull skin, while BHA’s the pore-clearing pro for oily or acne-prone types. Start slow, use sunscreen, and give your skin time to show off. Skincare’s a personal adventure, so have fun finding what works.

- Option 1: Alternate Days: Use AHA one night (for glow) and BHA the next (for pores). This keeps irritation at bay while tackling everything.
- Option 2: Targeted Use: Apply BHA to oily spots (nose) and AHA to dry or dull areas (cheeks). I do this when my forehead’s greasy but my cheeks are flaky.
- Option 3: Combo Products: Some formulas mix low doses of both (e.g., Paula’s Choice CLEAR Exfoliant). Great for cautious beginners.
