1. Whether one is 16, 25 or 45, taking care of one's skin is always a priority and to progress further we will understand the fact that our skin has three layers which is elucidated below:
(a) Epidermis :- It is the outer protective layer, which is there to keep out water, pollutants, the sun’s harmful rays and bacteria.
(b) Dermis :- It is the support structure of the skin, which lies below the epidermis. This layer is made up of blood vessels, nerves , sweat glands and sebaceous glands. Sweat glands help maintain one's body temperature. Sebaceous glands secrete an oil called sebum which helps to keep the skin moist.
(c) Subcutaneous tissue :- It is a fatty tissue layer below the dermis, which gives shape to one's body as well as keeps one's body as well as keeps one's body heat in and the cold out.
