Dr. Kadir Exclusive Restore Hydroxy Retinol Serum

The process of epidermal cell differentiation begins after the formation of cells in the basal layer. In the upper layers of the skin, cells undergo changes in form and function, and finally form the stratum corneum - a skin barrier that consists of dead flat cells tightly connected to each other. Between the cells there is a fatty waxy substance.

The end of the process is exfoliation (decquamation) - the removal of dead cells from the outer layer of the epidermis. Any dysfunction in the differentiation process will lead to a damaged skin barrier, dry skin or even scaly skin.

Retinol affects the process of differentiation of epidermal cells and the speed of regeneration of the epidermis. Alpha-hydroxy acids also affect the renewal of the epidermis and promote the exfoliation process by weakening the strong bonds between cells in the stratum corneum.

In addition, both Retinol and Alpha Hydroxy Acids affect the quality of the components in the deeper layers of the skin and therefore improve the texture and relief of the skin.

Thus, the combination of alpha hydroxy acids in the correct concentration and pH level with retinol is beneficial for skin texture, skin tone and skin hydration.
