Mandelic acid is an alpha-hydroxy acid (AHA) extracted from bitter almonds, and has gained popularity in cosmetics for its exfoliating properties and skin benefits. With larger molecules than some other acids, such as glycolic acid, mandelic acid is known for providing a gentle and less irritating exfoliation. This acid promotes cellular renewal, helping to improve skin texture, reduce dark spots, and fine lines. Additionally, it is known for its ability to address issues of hyperpigmentation and acne.
