What Are AHAs in Skincare? A Beginner's Guide to Alpha Hydroxy Acids

What Are AHAs?

AHA stands for Alpha Hydroxy Acid, a group of water-soluble acids derived from natural sources like fruits, sugar cane, and milk. In skincare, they're primarily used for gentle exfoliation - meaning they remove the top layer of dead skin cells to reveal smoother, more radiant skin underneath.

How Do AHAs Work?

Your skin naturally sheds dead cells every 28 days, but sometimes that process slows down - especially due to aging, pollution, or stress. AHAs help speed up that process by loosening the bonds between dead skin cells.

This allows:

- Brighter, more even skin tone

- Fewer clogged pores

- Better product absorption

- Smoother texture over time

Common Types of AHAs

Glycolic Acid

Derived from sugar cane. Smallest molecule size; penetrates deeply. Great for pigmentation, fine lines, and uneven skin tone.

Lactic Acid

From milk. Gentler than glycolic acid. Ideal for dry or sensitive skin, dullness, and uneven texture.

Mandelic Acid

From bitter almonds. Well-tolerated by acne-prone or sensitive skin types.

Who Should Use AHAs?

AHAs are suitable for:

- Dull or uneven skin

- Dark spots and pigmentation

- Mature skin with fine lines

- People looking for smoother texture

Caution: AHAs make your skin more sensitive to the sun. Always use sunscreen if you're incorporating them into your routine.

How Are AHAs Different from BHAs?

AHAs are water-soluble - they work on the surface of the skin.

BHAs (like Salicylic Acid) are oil-soluble - they go deeper, into pores.

If you're dealing with acne or blackheads, BHAs may be more effective. But for glow and pigmentation, AHAs are your go-to.

How to Start Using AHAs

Start slow - 2-3 times a week, depending on your skin type. You'll find AHAs in:

- Cleansers

- Toners

- Serums

- Peels

Avoid layering AHAs with retinoids or Vitamin C unless under dermat supervision.

Where to Find AHA-Based Products?

Look for gentle cleansers or exfoliants with Glycolic or Lactic Acid.

Try this: Ethiglo Facewash (by our brand) contains a dermatologist-approved blend of AHAs and BHAs to exfoliate, brighten, and even out your skin tone - without overdrying.

Final Takeaway

AHAs are one of skincare's most researched and effective ingredients. If you're looking for that 'post-facial' glow in your everyday routine, this is where to start - gently, consistently, and with sunscreen always by your side.
