Keratolytic are substances that help break down and remove excess keratin in the skin and are commonly used in dermatology to treat conditions like acne, psoriasis, dandruff, and calluses. They work by softening and loosening the outer layer of the skin, making it easier to shed dead skin cells.
Some common keratolytic agents include salicylic acid, urea, lactic acid, and glycolic acid. These ingredients are often found in medicated shampoos, topical creams and lotions designed to improve skin texture and hydration. Professional chemical peels often use keratolytic acids for deep exfoliation and skin renewal.
Keratolytic can make your skin more sensitive to the sun, so it’s important to use sunscreen when outdoors.
