Hello,
Keratosis pilaris is also called the chicken skin and occurs when Keratin, accumulates within the hair follicles forming numerous tiny rough bumps on the skin. Some of the treatment options for keratosis pilaris are Creams containing the acid form of vitamin A, Tretinoin, adapelene and triamcinolone. Exfoliation, intensive moisturizing creams, creams and lotions containing alpha hydroxy acids and urea may be used to temporarily improve the appearance and texture of affected skin.
I hope it helps. Take care and regards.
