Which type of chemical exfoliant works from the inside out?

The correct answer is AHA, or Alpha Hydroxy Acids, which are known for their ability to work from the inside out. AHAs are water-soluble acids derived from fruits and milk, and they primarily exfoliate the surface of the skin by dissolving the bonds that hold dead skin cells together. This action not only helps to improve the texture and clarity of the skin but also stimulates the production of collagen and elastin, which are essential for maintaining youthful, plump skin.

The effectiveness of AHAs in addressing issues like hyperpigmentation, sun damage, and the signs of aging stems from their ability to penetrate the skin more deeply than just surface-level exfoliants. They encourage the shedding of damaged skin layers while promoting the growth of new skin, ultimately resulting in a smoother and more radiant complexion over time.

While other exfoliants such as BHA (Beta Hydroxy Acid) primarily target oiliness and acne, and PHA (Polyhydroxy Acid) offer gentler exfoliation ideal for sensitive skin, it is the AHA's deeper action that makes it particularly effective for overall skin renewal. Enzyme exfoliants, on the other hand, work by breaking down the keratin proteins in the skin's surface,
