Which ingredient is commonly included in exfoliants to help remove dead skin cells?

AHA (Alpha Hydroxy Acid)
Ceramides
SPF (Sun Protection Factor)
Antioxidants

The correct answer is: AHA (Alpha Hydroxy Acid)

AHA, or Alpha Hydroxy Acid, is a key ingredient frequently found in exfoliants due to its ability to effectively dissolve the bonds that hold dead skin cells together on the surface of the skin. This action promotes the shedding of those cells, leading to a smoother and more radiant complexion. AHAs, which are typically derived from fruits, milk, or sugar cane, not only enhance the process of exfoliation but can also help improve skin tone and texture over time by stimulating cell turnover. Other options like ceramides primarily focus on moisturizing and protecting the skin barrier, while SPF is related to sun protection, shielding skin from UV rays, and antioxidants work to combat free radicals, providing protection against environmental damage. These ingredients play vital roles in skin care but do not specifically contribute to the removal of dead skin cells in the same manner as AHAs.
