Exfoliants in skincare are products that help remove dead skin cells, unclog pores, and promote skin renewal. They come in various forms, such as physical scrubs or chemical formulations containing ingredients like alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs). Exfoliants help improve skin texture, reduce dullness, and can be beneficial for addressing issues like acne, fine lines, and hyperpigmentation, leaving the skin looking smoother and more radiant.
