How can you drive a peel deeper into the skin?

To drive a peel deeper into the skin, the application of heat is a critical factor. When heat is applied, it can increase the permeability of the skin and enhance the penetration of the active ingredients in the peel. Heat can cause the skin to relax, leading to a more effective and uniform absorption of acids. This allows the peel to penetrate the epidermis more efficiently and reach the dermal layers if the formulation permits.

While higher concentrations of acid can also drive a peel deeper, and extended application time may further enhance penetration by allowing the chemicals to remain on the skin longer, heat is particularly effective due to its ability to temporarily alter the structure of the skin barrier, making it more receptive to the peel.

Massage, on the other hand, might be counterproductive to deeper penetration, as it could stimulate the skin and cause increased circulation that leads to transient redness and irritation, potentially limiting the peel's effectiveness. Thus, the combination of increased temperature and the chemical exfoliation properties of the peel itself is generally the most effective method to achieve a deeper penetration into the skin.
