What is keratosis pilaris?

Follicular plugs: Keratosis pilaris is plugging of hair follicles, typically on the upper arms and thighs. It is thought to be in the spectrum of atopic dermatitis (or eczema). The roughness can be reduced temporarily by amlactin lotion, which contains 12% lactic acid. Unfortunately, there is no cure.

Rough bumps: It's a genetically inherited condition that causes bumps to form around the hair follicles on the upper arms and can also affect the thighs. It looks and feels like rough goose bumps and can be confused with acne. There are treatments that can help lessen the rough bumps such as urea, glycolic acid, Lactic Acid but they get worse if you stop using the products.
