To understand how moisturisers work, we need to first understand our skin. Our skin has primarily three layers: Epidemis, Dermis, Hypodermis. The epidermis is the outermost layer of the skin. It acts as a barrier, protecting the inner layers of the skin from environmental stressors such as pollution, dust, UV rays. The dermis is the middle layer of the skin. It contains nerves, blood vessels, hair shafts, sweat and sebaceous glands The hypodermis comes after the epidermis and the dermis.
