Mandelic acid is an alpha-hydroxy acid (AHA) derived from bitter almonds. It is synthesized through the hydrolysis of an extract of bitter almonds. This process breaks down the natural compounds within the almond extract, resulting in the isolation and purification of the desired acid. The final product is a crystalline solid, soluble in water and alcohol, suitable for use in various applications.
This specific AHA offers a unique set of benefits, particularly in skincare. Its larger molecular size compared to other AHAs like glycolic acid results in slower penetration into the skin. This characteristic makes it a gentler exfoliant, reducing the risk of irritation and inflammation, making it suitable for sensitive skin types. Historically, it has been employed to treat various skin conditions, including acne, hyperpigmentation, and fine lines, capitalizing on its exfoliating and antibacterial properties.
