Abstract: The present invention relates to a cosmetic process which applies onto the skin a self-standing cosmetic sheet for the skin, comprising:
at least one biocompatible and/or biodegradable hydrophobic polymer layer
wherein
the self-standing cosmetic sheet has a thickness of from 10 to 1000 nm, preferably from 30 to 500 nm, and more preferably from 50 to 300 nm. The cosmetic sheet according to the present invention may comprise at least one cosmetic active ingredient.
The cosmetic sheet used in the present invention is very thin and not easily perceived on the skin; can be prepared with a variety of materials such as a biocompatible and/or biodegradable material; and can adhere well onto the skin without any adhesive layer so that it is less irritable or no irritable to the skin.-
