Which substance is commonly used as a skin exfoliant in esthetic practices?

Exfoliation is a vital part of skin care that helps to remove dead skin cells, improve skin texture, and enhance the overall appearance of the skin. In esthetic practices, several substances are commonly used for exfoliation, all of which have different properties and benefits.

Salicylic acid is a beta hydroxy acid (BHA) that penetrates deeper into the pores, making it particularly effective for oily and acne-prone skin. It not only exfoliates the surface layer of dead skin cells but also helps to reduce inflammation and clear clogged pores.

Glycolic acid, on the other hand, is an alpha hydroxy acid (AHA) derived from sugar cane. It is known for its small molecular size, which allows it to penetrate the skin easily. Glycolic acid is effective for surface exfoliation and is often used to improve skin texture, reduce fine lines, and brighten the complexion.

Lactic acid, another AHA, is derived from milk and is known for its gentle exfoliating properties. It is particularly suitable for sensitive skin types and aids in hydration while also removing dead skin cells. Lactic acid helps to brighten the skin and improve its overall glow.
