The Science Behind Chemical Peels: Types, Benefits, and What to Expect

Chemical peels are one of the most effective treatments for improving skin texture, tone, and appearance. Let's dive into the science behind these transformative treatments.

What Are Chemical Peels?

Chemical peels use specific acids to remove damaged layers of skin, revealing fresh, healthy skin underneath. This controlled injury triggers the skin's natural healing process, stimulating cell turnover and collagen production.

How Chemical Peels Work:

1. Exfoliation: Acids break bonds between dead skin cells

2. Penetration: Active ingredients reach deeper skin layers

3. Stimulation: Triggers cellular renewal and repair

4. Regeneration: New, healthy skin cells form

5. Improvement: Enhanced texture, tone, and appearance
