From the outside to the inside , the body skin is divided into the stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm and stratum basale , after through stratum corneum , stratum lucidum , stratum granulosum , stratum spinosm EGF can reach the stratum basale: accelerate the basal cells prpliferation and differentiation , reverse matured cells' differentiation to make stem cells that will form a " stem cells island " with a certain amount , which accelerate the generation of new cellls , make senescent cells keratinize and shed rapidly , make broken and denatured collagen fibers and elastic fibers repaired , so the skin's elasticity increase , and the wrinkles calm down or disappera gradually .
