Which ingredient is most commonly found in products aimed at exfoliation?

Salicylic acid is widely recognized for its effectiveness in exfoliation, particularly when it comes to treating acne-prone skin. This ingredient is a beta hydroxy acid (BHA) that works by penetrating deep into the pores, helping to dissolve the oils and debris that can lead to breakouts. In addition to its pore-clearing abilities, salicylic acid promotes the shedding of dead skin cells from the surface of the skin, resulting in a smoother texture and a more even tone.

Products designed for exfoliation commonly incorporate salicylic acid because it not only facilitates physical exfoliation, but also provides chemical exfoliation, making it versatile for various skin types, especially oily and combination skin. This dual-action property is essential for achieving effective exfoliation without causing irritation.

In contrast, ingredients like collagen play a role in hydrating and plumping the skin, but they do not possess exfoliating properties. Retinol, while beneficial for skin turnover and addressing fine lines and wrinkles, is distinct from the direct exfoliation that salicylic acid provides. Aloe vera is primarily used for its soothing and hydrating capabilities, rather than for exfoliating the skin. Thus, salicylic acid stands out as the most common ingredient associated with exfoliation in skin
