How do AHAs and BHAs primarily differ?

1. AHAs are for oily skin, BHAs are for dry skin

2. AHAs are oil-soluble, BHAs are water-soluble

3. AHAs are used for surface exfoliation, while BHAs penetrate deeper

4. AHAs are natural, BHAs are synthetic

The correct answer is: AHAs are used for surface exfoliation, while BHAs penetrate deeper

AHAs, or alpha hydroxy acids, and BHAs, or beta hydroxy acids, are both used in skincare for exfoliation, but they serve different purposes based on their chemical properties and how they interact with the skin. The correct distinction between them is that AHAs are primarily used for surface exfoliation, while BHAs are known for their ability to penetrate deeper into the pores. AHAs, which are water-soluble, typically come from natural sources such as fruits and milk. They work primarily on the skin's surface, effectively removing dead skin cells, which can help improve the overall texture and appearance of the skin. This makes AHAs especially beneficial for dry and sun-damaged skin, as they promote hydration and can aid in evening out skin tone. On the other hand, BHAs are oil-soluble, allowing them to penetrate oil-filled pores more effectively. This deep penetration enables BHAs to exfoliate from within the pores, making them particularly effective for oily and acne-prone skin types, as they can help reduce blockages and prevent breakouts. Understanding these differences is crucial for choosing the right type of exfoliant based on specific skin needs. The distinction based on their exfoliation depth—surface for AHAs and deeper for BH
