BHA and AHA, 2 approaches, one goal.

BHAs (beta-hydroxy acids) and AHAs (alpha-hydroxy acids) are more than just complex acronyms. They're powerful agents that transform skin thanks to their exfoliating properties. Let's dive into the mechanisms of action of these chemical exfoliants and understand how they promote cell renewal for glowing skin.

Mechanism of action of BHA/AHA

Chemical exfoliation : This process uses chemicals like acids to gently remove dead skin cells. This improves texture, reduces blemishes, and stimulates collagen production, resulting in brighter skin. BHAs and AHAs are acids that aid in this exfoliation by gently sloughing off dead skin to reveal fresh, younger-looking skin. Removing dead skin cells encourages the growth of new skin cells, which improves the overall appearance of the skin.

BHA (salicylic acid)

BHA is oil-soluble, effectively penetrating pores, removing impurities and excess sebum, and thus acne and blackheads. It is suitable for oily skin and is an excellent choice for treating follicle-level problems. 

AHA (Glycolic, Lactic, Mandelic Acids)

AHAs are water-soluble and will remove dead surface skin cells. Their action promotes a smoother texture, reduces dark spots, and adds brightness. This makes them ideal for dry or mature skin.

Precautions for use

It's important to use these acids in the evening, and to start gradually to get your skin used to the product. Ideally, use it one to three times a week, remembering to apply sunscreen every morning.

Do not mix with other acids, retinol or vitamin C, do not over-exfoliate.
