Human skin is a miraculous organ; it works harder than it should. Our skin is the largest organ in the body, and it consists of three layers, epidermis, dermis, and hypodermis;
The epidermis is the outer layer of your skin;
It has multi-function, like regulating a body temperature and a waterproof shield to keep the nutrients from leaking out and prevent moisture loss. It defends against UV rays damage protects our immune system by fighting and rejecting organisms to enter our body.
The epidermis consists of layers of flattened cells;
The main three types of the epidermis:
- Keratinocytes (skin cells)
The primary type of cell is found in the epidermis. It forms a barrier to protect us from environmental damage.

- Melanocytes (Pigment-producing cells)
The function of melanocytes is to produce melanin, which is the pigment that gives colour to our skin, hair, and eyes. The primary role of melanin is to protect the skin from getting UV radiation damage. People with darker skin are more prone to get sunburnt than people with lighter skin tone.
- Langerhans cells (immune cells)
The function of Langerhans cells is responsible for the immunity role. It acts as an antigen and response to any virus that wants it to enter our body. The cells are adaptive and responsive to inflammation and intolerance by interpreting the microenvironmental when encountering foreign substances such as HIV and other viral infections that enter the body via the skin.
Our skin is very busy keeping our body healthy by protecting our skin from getting environmental damage and guarding the viral infections that may enter the body via skin contact. Maintaining healthy skin is also very important to our health.
