Epidermis – The outer layer of your skin
The epidermis forms a barrier to protect your skin from external influences. It also keeps moisture locked in.
Dermis – The link between the epidermis and subcutis
The dermis contains a network of collagen and elastic fibres, which provide your skin with its elasticity and firmness.
Your levels of collagen and intact elastic fibres reduce constantly with age, as does your skin’s elasticity and tone.
Subcutis/hypodermis – The lowest layer of skin
The subcutis mainly consists of connective and fatty tissue.
The skin ageing process can deplete the lipid-storing cells in your fatty tissue. This can reduce the thickness of your skin and cause wrinkles to appear.
