The skin is made up of three layers, which all perform their own unique role in keeping your skin healthy:
The Epidermis is the layer that we treat through skincare.
It is the first and outermost protective layer of your skin, responsible for your skin colour, tone and appearance. If the Epidermis is damaged or impaired, this can cause premature ageing, dryness and skin issues.
The Epidermis is not just one single layer, though; it is made up of its own series of layers,
starting with a top layer - the Stratum Corneum - which is made up of old dead skin cells. Through your skin’s natural renewal cycle, these old cells are replaced by new cells which are made in the deeper Epidermis layers.
The next layer of your skin is the Dermis, the thickest layer of the skin.
The Dermis is made up of all kinds of vital vessels, tissues and nerve endings, along with hair follicles and sweat glands. This is where the The Sebaceous glands that produce oil for your skin are located.
The Hypodermis, or subcutaneous fat layer, is the deepest layer of skin. It is where body fat is stored and helps your skin to absorb impact.
Knowing the structure of your skin can help you better understand what a product is doing (or in some cases failing to do) for you and therefore make healthy, science based decisions about what you put on your skin.
