Skin ageing of facial skin involves ageing of multiple skin layers:
- the epidermisshows irregularities,
- the dermis become thinner and less elastic. The two important components in how the skin changes over time are collagen and elastin. Collagen and elastin both contribute to the skin’s strength and elasticity. Aging and environmental factors (sun damage) make it harder for your body to produce these components.
- the subcutaneous fat volume decreases and the fat pads slide downwards, leading to nasolabial folds and marionet lines.
But ageing also involves bone loss in facial bones leading to loss of support. This leads to excess skin and soft tissue accumulation near the jaw and chin leading to the formation of jowls. This is accentuated by the downward pull of the superficial neck muscles which also leads to laxity of the skin of the neck.
Saggy skin is less firm and less elastic skin. This is usually more pronounced in the lower face and neck and often make us look older and tired.
Not only face and neck, also body skin reduces collagen and elastin content over time and becomes saggy. The main area of concerns are: upper arms, abdomen, buttocks and upper legs.
