Alpha-hydroxy acids (AHAs) are a group of organic acids commonly used in the cosmetic and skincare industry. These acids are derived from natural sources such as fruits, milk, and sugar cane. They are known for their exfoliating properties and are used to treat various skin conditions such as acne, hyperpigmentation, and fine lines.
Alpha-hydroxy acids are a group of organic acids that have a hydroxyl group attached to the alpha position of the carboxyl group. These acids are water-soluble and have a low molecular weight, which allows them to penetrate the skin easily.
Alpha-hydroxy acids have been used for centuries in traditional medicine to treat various skin conditions. The use of AHAs in skincare products became popular in the 1990s when scientists discovered their exfoliating properties.
