What type of product is frequently used in chemical exfoliation?

Moisturizers
Salicylic acid
Sunscreen
Toners

The correct answer is: Salicylic acid

Chemical exfoliation primarily relies on specific acids and chemicals to help remove dead skin cells from the surface of the skin, promoting cell turnover and improving skin texture. Salicylic acid is a beta hydroxy acid (BHA) known for its ability to penetrate oil and unclog pores, making it particularly effective for treating acne-prone skin. Its exfoliating properties stimulate cell turnover, leading to smoother, clearer skin. Moisturizers, sunscreens, and toners do not typically provide the same exfoliating action as salicylic acid. Moisturizers are designed to hydrate and support the skin’s barrier function, while sunscreens protect against UV damage. Toners can help balance the skin's pH and remove residual impurities, but they do not perform the function of breaking down dead skin cells like salicylic acid does. Thus, salicylic acid stands out as the primary ingredient used in chemical exfoliation treatments.
