Acid exfoliants for the face: the advantages and dangers of the product –

What are acid exfoliants and what are their types?

Known for some time among the dermatological community and highly indicated, the acid exfoliants are one of the options for renewing skin cells. Phave pH less than 7 and are considered chemical exfoliants (that is, they don’t have those granules that we are used to from physical facial exfoliants) accelerating the natural process of renewal of the most superficial layer of the skin through the peeling. This removal from the surface, together with the penetration of the acid, causes an inflammatory reaction that contributes to the synthesis of collagen and the tissue repair, leaving the skin with more softness, shine It is vice.

There are several types of acids, for different purposes, and that vary in the intensity of penetration into the skin. “O glycolic acid It is widely used for rejuvenation, cell renewal and whitening. O acid salicylic acid for acne and oily skin. The mandelic for stained and oily skin. O acid lactic for cell renewal, rejuvenation and acne-prone skin” informs the dermatologist Natasha Crepaldi

The intensity of penetration into the skin depends on the size of its structures. The larger the molecular structure, the “softer” the effect will be in contact with the skin. “If you have super sensitive skin, a mandelic acid might be the best option for you. It has a larger molecular structure than other acids, such as glycolic and salicylic, so it does not penetrate as deeply,” explains the dermatologist. André Braz.

“already the glycolic acid It is one of the smallest molecules in the family of alpha hydroxy acids. In practice, this means that it is water-soluble and penetrates deep into the skin. It is a high-impact formula that is excellent for acting against skin aging and acne. O lactic acid it is of animal origin and its main function is exfoliation, that is, it removes dead skin cells promoting smoother and younger skin. When we talk about it, know that it has an intermediate molecular weight, which means that it does not penetrate so deeply into the layers of the skin. It also has a humectant capacity, retains water molecules – and is indicated for combination skin, for example” continues the professional. “already the salicylic acid it is a beta hydroxy acid of keratolytic and anti-inflammatory action. In simple terms, it promotes gentle exfoliation and the reduction of the inflammatory process (causes mild flaking on the skin), helps to reduce sebum production, diminishes acne imperfections, unclogs pores and improves skin texture. oily and acneic.”
