Exfoliating is the secret to removing dead skin cells and reviving your glow. In this blog, we’ll explain the differences between AHA, BHA, PHA, and enzymes — and help you find the right products for your skin type.

What is exfoliation?

Exfoliation is the process of removing dead skin cells from the surface of the skin. This can be done in two ways: mechanically (with grainy scrubs) or chemically (with acids like AHA, BHA or PHA). Chemical exfoliation is often gentler and more effective.

Types of exfoliants

✧ AHA (Alpha Hydroxy Acid)

AHAs like glycolic and lactic acid work on the skin’s surface and are great for dry, dull, or mature skin. They offer mild hydration and boost cell turnover.

✧ BHA (Beta Hydroxy Acid)

BHAs like salicylic acid penetrate deeper into the pores and dissolve excess sebum. Perfect for oily skin, clogged pores, and breakouts.

✧ PHA (Poly Hydroxy Acid)

PHAs are the gentlest form of exfoliant, ideal for sensitive skin. They exfoliate mildly and help retain moisture with a lower risk of irritation.

✧ Enzymes

Enzymatic exfoliants (like papaya or pineapple) gently dissolve dead skin cells using natural fruit enzymes — safe for even the most sensitive skin types.

Frequently Asked Questions About Exfoliation

✧How often should I exfoliate?

It depends on your skin type and the type of exfoliant. AHAs and BHAs are usually used 2–3 times per week, PHAs and enzymes can be used more often.

✧Can I combine exfoliation with retinol?

Yes, but not on the same day—especially if you have sensitive skin. Alternate between the two and build up gradually to avoid irritation.

✧Should I exfoliate in the morning or evening?

Evening is preferred because your skin repairs overnight. Always wear SPF the next day!

✧Is exfoliation safe for sensitive skin?

Yes, choose PHAs or enzymes and introduce them slowly. Stop if redness or tingling occurs.

✧What if my skin reacts to exfoliation?

Pause use, focus on hydration, and avoid other active ingredients. Restart gradually once your skin has calmed.
