What ingredient is commonly used in skin exfoliation products?

Alpha hydroxy acids (AHAs) are widely recognized for their effectiveness in skin exfoliation. They are water-soluble acids sourced from fruits that help to slough off dead skin cells and enhance the skin's texture and brightness. By promoting cell turnover, AHAs can significantly reduce the appearance of fine lines, sun damage, and uneven skin tone. They work primarily on the skin's surface, making them particularly beneficial for individuals aiming to achieve smoother and more radiant skin.

While other ingredients like salicylic acid, beta hydroxy acids (BHAs), and glycolic acid also play roles in exfoliation, AHAs, specifically, are the go-to choice for enhancing overall skin appearance and hydration. Salicylic acid is often more suitable for acne-prone skin due to its oil-soluble properties, allowing it to penetrate more deeply into pores. Glycolic acid, which is a type of AHA, specifically acts to exfoliate and rejuvenate the skin but is typically categorized under the broader AHA category. Understanding the role AHA plays in skincare helps in selecting the right products for desired skin outcomes.
