AHAs or alpha-hydroxy acids are gentle exfoliants made from fruit acids. Unlike the classic scrub, they gently remove dead skin that accumulates on the surface of the skin without having to rub. They are generally found in the form of glycolic acid, the best known AHA because it is more effective. It is also one of the flagship products of our Exfoclear face and body exfoliant, which renews skin cells without attacking the skin barrier.
What are AHAs?
AHAs are a combination of fruit acids of natural or synthetic origin. There are products based on synthetic acids on the market but these are generally not recommended in view of the risk of side effects. It is therefore preferable to favor natural products that better respect the pH of the skin.
In general, AHAs come from: glycolic acid from sugar cane, matic acid from apples and lactic acid from milk. These types of AHA are the most used in cosmetics for their ability to penetrate the skin. We then speak of chemical exfoliation because it does not require a mechanical action with grains or beads.
The combination of these acids can accentuate the "new skin" effect sought when using an exfoliant. For example, Exfoclear contains an ideal mixture of lactic acid and glycolic acid, which makes it perfectly effective in eliminating dead cells that clog pores and dull the skin.
It is quite possible to find both chemical and mechanical exfoliants on the market, such as our Exfoclear exfoliating gel. It contains :
- sugar cane, maple, blueberry, lemon and orange fruit acids to unclog pores, boost collagen production and stimulate cell turnover.
- Apricot kernel powder to refine skin texture through mechanical exfoliation.

What are the benefits of AHAs?
Fruit acid AHAs have both exfoliating and antioxidant properties for radiantly beautiful skin.
- They promote the production of collagen, a natural protein produced by the body and responsible for the elasticity and firmness of the skin.
- They accelerate cell renewal for a rejuvenated effect after each exfoliation.
- They also provide deep hydration to revive the complexion and improve the elasticity and firmness of the skin thanks to their ability to absorb water.
- Their chemical exfoliation system tightens pores, improves skin texture, fades pigmentation spots and unifies the complexion for an immediate healthy glow effect.
Who can use AHA exfoliants?
We generally recommend the use of exfoliants with AHAs to smooth the texture of the skin on both the face and the body. Oily-prone skin is strongly affected by their use since they regulate sebum production, smooth microcysts (small pimples closed under the skin), prevent the appearance of acne pimples and comedones. In these specific cases, it is advisable to exfoliate the skin 1 to 3 times a week in order to unclog pores, erase superficial marks on the skin and blur imperfections.
AHA-based exfoliants may also be suitable for sensitive, dry and dehydrated skin as they limit feelings of tightness and do not dry out the skin. However, this remains tricky. A test application on a small part of the skin is recommended beforehand so as not to irritate or dry out the most sensitive skin. Use once a week or every two weeks is then preferable.
