BHA and AHA, 2 approaches, one goal.

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

BHA/AHA mechanism of action

Chemical exfoliation: This process involves using chemicals such as acids to gently remove dead skin cells. This improves texture, reduces imperfections and stimulates collagen production, resulting in more radiant skin. BHAs and AHAs are acids that participate in this exfoliation, promoting the gentle detachment of dead skin to reveal fresh, younger-looking skin. Removing dead skin cells encourages the growth of new skin cells, which will improve the skin's overall appearance. 

BHA (salicylic acid)

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

AHA (glycolic, lactic and mandelic acids)

AHAs are water-soluble, and will remove dead skin cells from the surface. Their action promotes a smoother texture, reduces blemishes and adds luminosity. 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, you should 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 overexfoliate.
