Is skin a material?
Thus, skin can be considered a layered composite material [10], where, from a mechanical viewpoint, each layer fulfills a certain function: the hard keratinized surface of the epidermis enhances toughness, the dermis provides load-bearing [9] properties, the hypodermis provides shock absorption.
What are the different types of skin?
Based on these characteristics, there are five types of healthy skin: normal, dry, oily, combination (both oily and dry skin) and sensitive.
