What ingredient is commonly used to exfoliate dead skin cells?

Alpha Hydroxy Acids (AHAs) are commonly used in skincare for their exfoliating properties. They are water-soluble acids derived from fruits such as glycolic acid (from sugar cane) and lactic acid (from milk). AHAs work by breaking down the bond between dead skin cells on the surface of the skin, facilitating their removal and revealing fresher, more radiant skin underneath. This makes them particularly effective for improving skin texture and promoting a more even skin tone.

While other ingredients listed, such as salicylic acid (a BHA) and retinol, also contribute to skin renewal and can aid in exfoliation, AHAs are particularly recognized for their role in this process, especially for those with dry or sun-damaged skin. This helps establish AHAs as the most representative option when discussing ingredients specifically focused on exfoliating dead skin cells.
