What is natural keratin? Keratin is an extremely tough, pliable and waterproof protein molecule naturally produced by your body. It’s in your hair, nails and outer skin layer. Natural keratin in your skin creates a strong barrier to protect and accounts for the durable structure of hair and nails.
Corns and calluses are deposits of keratin in a natural response to repetitive friction to thicken a skin area. Entrapped keratin is the cause for the formation of milia, sebaceous cysts and pilar cysts. Also, natural keratin can plug up a hair follicle resulting in keratosis pilaris. And excessive growth of keratin causes various keritosis skin conditions.
