The methods for how to exfoliate skin are mechanical, which uses tools like a washcloth, brush, sponge, or scrub; and chemical, which uses substances like alpha- or beta-hydroxy acids to dissolve dead skin cells.
How To Exfoliate Skin
Mechanically
In this method, with your tool, apply the product using small, circular motions for about 30 seconds. Take care to use only short, light strokes especially if you are using a brush or sponge. Finally, rinse off with lukewarm water.
Chemically
The chemical route usually involves using alpha- or beta-hydroxy acids, which work by dissolving dead skin cells. Alpha-hydroxy acid (AHA) is normally used to peel all skin types with low risk. It’s also often used in treatments for acne, scars, roughness, age spots, and hyperpigmentation. Can also improve wrinkled skin.
Some research suggests that it can prevent UV-induced skin tumors, and has antioxidant properties. Its ability to “reverse” aging lies in its ability to increase skin cell renewal. However, there are studies that say AHA can heighten skin sensitivity to UVB- irradiation, and uneven pigmentation due to sun exposure. Whether it helps or harms depends on the AHA concentration in the product.
Another chemical for how to exfoliate skin is beta-hydroxy acid (BHA), another commonly used ingredient in skin products. BHA may help reduce wrinkles and fine lines, enhancing skin texture. Listed on skincare labels usually as salicylic acid, the Food and Drug Administration deemed it safe to use when formulated to avoid irritation and when formulated to avoid increased sun sensitivity”.
