Which ingredient is commonly used in acid exfoliants?

• A. Salicylic acid
• B. Petroleum jelly
• C. Mineral oil
• D. Lanolin

Answer: (A)

Salicylic acid is commonly used in acid exfoliants because it is a beta hydroxy acid (BHA) known for its keratolytic properties, which means it helps to exfoliate the skin by breaking down the bonds between dead skin cells. This ingredient penetrates deep into the pores, making it particularly effective for treating oily and acne-prone skin. Its ability to improve skin texture and unclog pores makes it a popular choice among skin care professionals and in over-the-counter products. Other options like petroleum jelly, mineral oil, and lanolin are primarily occlusive agents or emollients, meaning they serve to moisturize and protect the skin by preventing water loss. They do not provide the exfoliating benefits that salicylic acid does, which is essential for anyone looking to promote cell turnover and achieve smoother skin.
