Chemical Exfoliants

Alpha Hydroxy Acids (AHAs): AHAs, like glycolic acid and lactic acid, work by breaking down the bonds between dead skin cells so they can be easily rinsed away.

Beta Hydroxy Acids (BHAs): Salicylic acid is the most common BHA. It works similarly to AHAs, but it's also oil-soluble, which means it can penetrate into pores to exfoliate inside as well as on the surface of the skin.

Polyhydroxy Acids (PHAs): PHAs, such as gluconolactone and lactobionic acid, are gentler than AHAs and BHAs. They don't penetrate as deeply into the skin, making them a good choice for sensitive skin types.

Enzyme Exfoliants: These use natural enzymes from fruits like papaya or pineapple to dissolve dead skin cells. They're usually gentler than AHAs, BHAs, or physical exfoliants, making them suitable for sensitive skin.

Retinoids: While not traditionally thought of as exfoliants, retinoids (like retinol and prescription retinoids) promote cell turnover and can help exfoliate the skin over time.
