From the left picture, you can see that our skin is made of layers—epidermis, dermis and hypodermis. The epidermis is the outermost layer of our skin where we feel various sensations brought by touch and temperature. This layer is where we wear our skin tone due to the melanin-producing cells called melanocytes. The more melanin, the darker our skin tones will be.


Next to the epidermis is the dermis. In this layer, connective tissues, sweat glands and hair follicles can be found. What happens in this layer affects the epidermis. For example, hair follicles blocked with oil will be seen as blackheads, while bacteria in hair follicles will lead to acne and pimples.

The innermost layer is the hypodermis where fats and connective tissues can be found.
