Alpha Hydroxy Acids (AHAs) and their Derivatives are a class of humectants commonly used in skin care products due to their exfoliating properties. AHAs, such as glycolic acid and lactic acid, originate from natural sources like sugar cane and milk. These compounds promote cell turnover by breaking down the bonds between surface skin cells, leading to a smoother appearance and reduced fine lines. Derivatives of AHAs may enhance their stability or effectiveness while minimizing irritation. They are often used in serums, creams, and peels for daytime use due to their mild exfoliation properties and ability to improve skin texture and tone. Regular application can help maintain youthful-looking skin by increasing hydration and promoting the renewal of the epidermis.
