What common skincare ingredient is known for its exfoliating properties?

Both salicylic acid and lactic acid are widely recognized for their exfoliating properties, making them effective ingredients in skincare products. Salicylic acid, a beta hydroxy acid (BHA), penetrates deep into the pores and helps to dissolve the bonds that hold dead skin cells together, facilitating their removal. This not only aids in refining skin texture but is particularly beneficial for individuals with acne-prone skin, as it can help in unclogging pores and reducing inflammation.

Lactic acid, an alpha hydroxy acid (AHA), is derived from milk and functions primarily on the surface of the skin. It is effective in gently exfoliating dead skin cells, promoting cell turnover, and enhancing skin hydration. Its exfoliating action helps to brighten the complexion, improve skin texture, and promote a more youthful appearance.

Together, these acids offer complementary benefits in exfoliating and improving the overall health and appearance of the skin. Their inclusion in the correct answer emphasizes the wide-ranging benefits and utility of chemical exfoliants in skincare regimens.
