Human skin consists of different parts that carry out different functions. I will answer the questions while also outlining the function of the part:
The epidermis is <span>the outer layer of skin that is responsible for the production of melanin and keratin.
Keratin is a protein substance necessary to healthy skin.
The dermis is the inner layer of the skin that contains hair follicles and sweat glands.
Sebaceous glands are responsible for the production of sebum
Sebum is an oily substance that protects the skin.
Acne is the result of sebum being trapped inn a follicle with a piece of dirt or bacteria.
Body odor results of sweat being allowed to sit on bacteria-crowded areas of the skin.
Washing is the best means of prevention of body odor and acne.
