By When it comes to glowing, youthful skin, exfoliation is everything. But if you’ve ever felt overwhelmed by the alphabet soup of acids—AHAs, BHAs, PHAs—you’re not alone. The big question on everyone’s mind is: “Which exfoliant actually works best for aging skin?”
Today, we’re putting the spotlight on the two most talked-about exfoliants in skincare—AHAs (alpha hydroxy acids) and BHAs (beta hydroxy acids)—and revealing which one is the ultimate glow-giver for smoothing fine lines, fading sun spots, and refreshing tired skin.
What Are AHAs?
AHAs are water-soluble acids derived from natural sources like fruit and milk. They work by dissolving the bonds between dead skin cells, allowing them to shed more easily and reveal brighter, smoother skin underneath.
Best AHAs for Anti-Aging:
- Glycolic Acid – The gold standard. Penetrates deeply to smooth wrinkles and boost collagen.
- Lactic Acid – More gentle, hydrates while exfoliating. Great for dry or sensitive skin.
- Mandelic Acid – Mild and ideal for reactive or rosacea-prone skin.
AHAs Are Great For: ✅ Dull skin ✅ Fine lines & wrinkles ✅ Uneven texture ✅ Hyperpigmentation & sun damage
What Are BHAs?
BHAs are oil-soluble acids that penetrate deeper into the pores. The most common BHA is salicylic acid, known for its ability to clear clogged pores and reduce inflammation.
Why Use BHAs for Aging Skin?
While BHAs are more famous for treating acne, they’re anti-inflammatory and great for aging skin that’s oily, acne-prone, or sun-damaged.
BHAs Are Great For: ✅ Enlarged pores ✅ Rough texture ✅ Blackheads & breakouts ✅ Combination skin with signs of aging
AHAs vs. BHAs: Which Wins for Anti-Aging?
The truth? Both acids can be powerful tools, but it depends on your skin type and concerns.
Choose AHAs If You Want To:
✨ Fade sun spots
✨ Smooth fine lines
✨ Improve radiance and skin texture
Choose BHAs If You Want To:
✨ Clear clogged pores
✨ Minimize rough patches
✨ Soothe redness and inflammation while exfoliating
✅ Pro Tip: Some products combine both acids for a powerful glow-up effect. Start slow and always use SPF, as acids increase sun sensitivity.
How to Safely Add Acids to Your Routine
- Start 2–3 times per week and increase gradually.
- Avoid mixing with strong retinoids or exfoliants on the same night.
- Hydrate and moisturize after use.
- Always wear SPF the next day!
FAQs
Q1: Can I use AHAs and BHAs together?
Yes—but proceed with caution. If your skin tolerates both, you can use them on alternate nights or choose a product that combines them in a balanced formula.
Q2: Which acid is better for mature, dry skin?
AHAs like lactic acid are better for dry or mature skin, as they exfoliate and hydrate at the same time.
Q3: Are exfoliating acids safe for sensitive skin?
Yes, but choose gentle formulas and introduce slowly. Look for lower concentrations and stick to lactic or mandelic acid.
Final Thoughts: The Glow Is in the Details
Whether you’re team AHA or team BHA, the key is using the right formula for your unique skin type and being consistent. Both can dramatically improve the look of fine lines, dullness, texture, and sun damage when used properly.
