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 achieve the 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!

Peel Strength

The strength of a peel is important (obviously). This is generally expressed as a percentage of the active ingredient. Stronger isn’t always better, especially with sensitive skins or specific problems

Peel Type

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 peel agent has different characteristics e.g. some easily dissolve skin oils, others have a small molecular size so can penetrate more deeply. It takes some knowledge to know which is the most appropriate for the skin condition.
