Your Guide to Brighter, Smoother, and Healthier Skin
What are Alpha-Hydroxy Acids?
Alpha-Hydroxy Acids (AHAs) are a group of naturally occurring and synthetically produced acids that gently dissolve the bonds between dead skin cells, promoting fresh, smooth, brighter-looking skin.
With advancements in dermatology, physical exfoliation (especially harsh scrubs) is no longer recommended — AHAs offer a safer, controlled, and more effective method of exfoliation.
Types of AHAs
There are several AHAs, but the two most researched and widely used are:
1. Glycolic Acid
- Derived fromsugarcane
- Has thesmallest molecular size, allowing deeper penetration
- Excellent fortextural concerns, pigmentation, and dullness
- Also boostshydration
2. Lactic Acid
-
- Derived frommilk products
- Larger molecular size →gentler exfoliation
- Ideal fordry, dehydrated, and sensitive skin
- Helps improve skin tone and hydration
Benefits of AHAs
-
AHAs provide multiple skin benefits, including:
- Gentle exfoliation, helping remove dead skin cells
- Fading sunspots and discoloration
- Brightening overall complexion
- Boosting collagen production
- Softening fine lines and wrinkles
- Reducing breakouts by preventing clogged pores
AHAs in Skincare Products
You’ll find AHAs in:
- Cleansers
- Serums
- Toners
- Creams
- At-home and professional chemical peels
Concentrations vary:
- 2–10%→ cleansers, toners, serums (OTC)
- 20–30%→ home peels
30–70% → professional peels (dermatologist only)
How to Use AHAs
- Applyafter cleansing and before moisturiser.
- Beginners should start with5–7% AHAs, 2x/week, then slowly increase frequency as tolerated.
- Those with very dry or sensitive skin shouldpatch test.
- Best used in thePM routine due to increased sun sensitivity.

Are AHAs Safe for Acne-Prone or Sensitive Skin?
✔ Acne-prone skin: Yes — AHAs help clear clogged pores and improve texture.
⚠️ Sensitive skin: Use cautiously. Start with low strength and discuss with your dermatologist if unsure.
Pregnancy & Breastfeeding Safety
⚠️ Use with caution.
AHAs are generally considered safe because only minimal amounts are absorbed through the skin. However:
- Stick to<10% concentrations
- Always wearsunscreen
- Avoid high-strength peels unless advised by your dermatologist
Pregnancy increases skin sensitivity, so proceed gently.
