The main factors that cause face to sag are face ageing and volume loss. Face ageing is the loss of collagen, elastin and natural hydrators from your face. It is a process that begins in your early twenties and becomes visible in your early thirties. Life-style factors such as smoking and sun exposure can affect the speed with which face ages.

Anti-ageing face treatments are based on the principle of stimulating face repair and thus the production of new collagen, elastin and face hydrators. Volume loss is the loss of subcutaneous fat (fat under the face) and moisture, leaving the face looking shrivelled, droopy and thin.
