The skin is made up of three layers – Epidermis, Dermis and Hypodermis. The skin acts as a barrier between our internal system and the external environment. The importance of skin care cannot be underestimated. Throughout our life it goes through numerous changes due to different factors such as aging, pollution, lifestyle, hormonal influences etc. But it somewhat always adapts to the changes that is until it can no longer cope with it, leading to a deterioration that can be seen externally and also internally where you have structural change.

Overview

EPIDERMIS

Outer layer of the skin that act as a barrier between the body and the environment. The outer most layers known as the stratum corneum is consists of older keratinocytes which are eventually shed and replaced by newer keratinocytes forming a skin barrier

Dermis

The middle layer of the skin that contain nerve glands, essential proteins, enzymes, blood cells, making it the skins operation centre. Contains collagen and elastin which provides structure to skin.

Hypodermis

this layer lies below both the epidermis and the dermis. It is comprised of mainly fat, blood vessels, and nerves. This layer acts as a cushion that also insulates the body

Sebaceous glands

Small oil-producing glands attached to hair follicles. This oil is known as sebum, lubricating and waterproofing the hair and skin. Sebaceous glands can be found everywhere

Elastin

Elastin is an essential protein that gives skin the ability to resume its shape after stretching or contracting. The breakdown of elastin leads to sagging skin. Sun exposure and repeated facial expression damages elastin

Collagen

The main structural protein that supports the skin and gives it structure. The degeneration of collagen leads to fine lines and wrinkles. Sun exposure is the main cause of collagen damage

Sebum

Sebum is secreted by sebaceous glands in human. It helps waterproof the skin. Sebum forms a film on the skin that keeps water in and irritants out

Blood vessels

Network of blood vessels is found in the dermis and subcutaneous layer. These vessels supply the skin with oxygen and nutrients. The blood vessels play a role regulating the body temperature
