Mandelic Acid
Mandelic acid is a gentle alpha hydroxy acid (AHA) derived from bitter almonds. It is popular in UK skincare for its ability to exfoliate the skin while being kinder than glycolic acid, making it suitable for sensitive and acne-prone skin. You will often find it in serums, toners and chemical peels at concentrations between 5-10%.
How it works in skincare
In cosmetics mandelic acid works by loosening the bonds between dead skin cells on the surface of the skin, encouraging gentle exfoliation and revealing smoother, brighter skin underneath. Because its larger molecular size means it penetrates more slowly than smaller AHAs, it tends to cause less irritation and redness. It is also oil-soluble, allowing it to work effectively on both the surface and within the pores, supporting a clearer complexion and more even skin tone.
