What does a chemical peel do to your skin?
Chemical peels are useful for a wide range of skin conditions. But why? What do they do?
How do chemical peels work?
They work by causing the body's healing response mechanism to be initiated through the deep exfoliation of the outer epidermal layers. This may involve the skin visibly “peeling”, although newer formulations aim for a more subtle shedding of cells, which has achieve same result.
In this way the rate of cell turnover is increased and the production of the skin's structural proteins (Collagen and Elastin) is enhanced.
A peel is a peel is a peel…? No!
The strength of a peel is import (obviously) This is generally expressed as a percentage of the active ingredient. Stronger isn’t always better, especially with sensitive skins or specific problems
But so is the specific chemical or enzyme used (Glycolic acid, Salicylic acid etc.).
The depth to which the peel penetrates the skin will vary with the particular peeling agent, and this will influence it's effects.
Each one has different characteristics - one might easily dissolve in skin oils. Another has a large molecular size, so doesn’t penetrate as deeply. It takes some knowledge to know which is most appropriate.
Layering of peels
Different agents will also produce different effects and so it is possible to layer different peels to achieve a tailored result.
