BHA

Unlike AHAs, which exfoliate the surface of the skin, BHAs work both on the surface and in depth. They are suitable for normal to oily skin that has enlarged and clogged pores and blemishes. The most famous BHA is salicylic acid, which is extracted from willow bark.

Thanks to their exfoliating action, BHAs rid the skin of dead cells that dull the complexion and clog pores. They thus help stimulate cell renewal, regulate bacterial flora and reduce imperfections by regulating excess sebum.

BHAs are also effective in treating dark spots and acne scars. Skin texture is smoother, pores are tightened and the face is more radiant.

For a more complete exfoliating action, you can combine AHAs and BHAs, but be careful not to use them daily, even on oily skin with imperfections, at the risk of damaging the skin's protective barrier, which is essential for its proper functioning.
