Azelaic acid is a dicarboxylic acid naturally produced by a yeast present on the skin (Malassezia furfur). It is also found in certain cereals such as wheat, barley, and rye. This versatile active is associated in scientific literature with soothing, purifying, and melanin-regulating properties.
Its mechanism of action is multiple. Azelaic acid is linked in scientific literature to inhibiting tyrosinase, the enzyme involved in melanin production, making it a documented active for helping even skin tone and reduce the appearance of pigmentation spots. It acts selectively on overactive melanocytes without affecting normal skin pigmentation.
Azelaic acid also has gentle keratolytic properties: it helps refine skin texture by promoting the removal of accumulated dead cells on the surface, contributing to improved skin radiance. Unlike other exfoliating acids, it is generally well tolerated by sensitive skin.
Its documented soothing and purifying properties make it an ally for blemish-prone skin. It helps reduce redness appearance and soothe discomfort sensations, while also helping limit blemish appearance.
In summary, azelaic acid is a complete active that simultaneously addresses blemishes, pigment irregularities, and dullness. Its good tolerance makes it suitable for many skin types, including sensitive skin.
