AN-Acide glycolique
Glycolic acid
| Type of ingredient | Exfoliant |
| Available forms | Toners, serums |
| Origin | It is an alpha-hydroxy acid (AHA) derived from sugar cane. Specifically for AHAs, it is one of the strongest and most potent; because it has the lowest molecular weight of all the alpha hydroxy acids, it penetrates the skin more easily. |
| Main benefits | Acts as a chemical exfoliant by loosening the bonds between dead skin cells while helping to treat acne. Glycolic acid also stimulates collagen production and acts as a humectant, drawing moisture from the skin. |
| Characteristics | It is a keratolytic agent, it loosens and eliminates dead cells on the surface of the skin, promoting cell renewal and bringing luminosity to dull complexions. |
| Target group | Glycolic acid is well tolerated by most skin types and is gentle enough that generally even sensitive skin can use it. |
| Frequency | This largely depends on your skin and the particular product you use, but in some situations it can be used daily. |
| Association | Other humectants, such as hyaluronic acid. |
| Dissociation/ Contraindication | Be especially careful when combining it with other acids and retinoids. People with eczema or a dehydrated complexion are particularly at risk as the Ph of the skin is altered during use and can alter the hydrolipidic film. |
| Side effects | At the end of the day, an acid is an acid. And that means there will always be a risk of redness, irritation and flaking, especially if your skin is sensitive to begin with. |
| Use | It is best to start using glycolic acid gradually and increase the frequency as your skin adjusts. Reserving the application for your nightly routine is also a good approach as it can make your skin more sensitive. During the day, always apply sunscreen after your moisturiser. |
