The Sephora Bright Skin Exfoliating Scrub is a skincare product designed to promote skin renewal and improve overall skin texture. The key active ingredients in this scrub include alpha hydroxy acids (AHAs) such as glycolic acid and lactic acid. AHAs are chemical exfoliants that work by breaking down the bonds between dead skin cells on the surface of the skin, allowing them to be sloughed off more easily. Glycolic acid, with a molecular weight of 76.05 g/mol, is known for its small molecule size which allows it to penetrate the skin effectively. It helps to exfoliate the skin by loosening the bonds between dead skin cells, leading to a smoother and brighter complexion. Lactic acid, with a molecular weight of 90.08 g/mol, also contributes to the exfoliating properties of the scrub. It helps to improve skin hydration and reduce the appearance of fine lines and wrinkles. Apart from AHAs, the scrub also contains physical exfoliants such as microbeads or granules that help to physically remove dead skin cells and impurities from the skin's surface. These ingredients work synergistically to provide a more thorough exfoliation and reveal fresher, more radiant skin underneath. The pH of the Sephora Bright Skin Exfoliating Scrub is carefully formulated to be suitable for most skin types, ensuring that the product effectively exfoliates without causing irritation.
