AN-Acide azelaique
| Type of ingredient | Exfoliant |

| Origin | It is dicarboxylic acid which helps to exfoliate the skin and is naturally synthesised by yeast. Azelaic acid is produced naturally on your own skin by your own yeast, but you can also make it in a laboratory. It can also come from cereals. |
| Main benefits | Fights acne, treats rosacea, lightens dark spots and removes dead skin cells. |
| Characteristics | As well as being comedolytic (meaning it prevents blackheads) and working to exfoliate deep into the pores, it is also a keratolytic (decreases keratin), anti-inflammatory and has antioxidant properties. |
| Target group | In general, anyone with skin prone to acne, rosacea and hyperpigmentation would benefit from the action of azelaic acid. It is even safe for pregnant women. |
| Frequency | In general, anyone with skin prone to acne, rosacea and hyperpigmentation would benefit from the action of azelaic acid. It is even safe for pregnant women. |
| Association | It is easily combined with a routine containing alpha-hydroxy acids (AHA), beta-hydroxy acid (BHA) and retinol. |
| Dissociation/ Contraindication | Azelaic acid can be used safely with most active ingredients in cosmetics. |
| Side effects | A slight irritation may be felt but overall it is a mild type of acid. |
| Use | Apply a thin layer of the product to clean, dry skin twice a day, morning and evening. For sensitive skin, it is recommended to use once every two days. To help the azelaic acid absorb and work even more effectively, it is recommended that you first apply your AHA (such as glycolic or lactic acid), BHA (salicylic acid) or retinol to open up the skin and accept the azelaic acid more easily. Then follow with a moisturizer and a sunscreen with an SPF of at least 30 in the morning. |
