Elastin is an important protein found in the skin, blood vessel walls, lungs and connective tissues, providing flexibility and resilience. Like collagen, it is a structural protein and plays a critical role in keeping the skin elastic and firm.
The roles of elastin
Skin elasticity: Keeps the skin taut and firm; as elastin levels fall with age, sagging develops in the skin.
Blood vessel elasticity: Elastic fibres help blood vessels narrow and widen, regulating blood flow.
Lung function: Helps the lungs adapt to breathing in and out.
Support in connective tissue: Structures such as tendons and ligaments gain their elasticity from elastin.
Elastin loss and ageing
As we age, elastin production decreases and the existing elastin fibres begin to become damaged. This leads to the formation of wrinkles and sagging in the skin. Some factors that accelerate elastin loss are:
UV rays (sunlight)
Smoking and air pollution
Sugar consumption (the glycation process)
Free radicals and oxidative stress
Factors that support elastin production
Sun protection: Sunlight breaks down elastin fibres, causing premature ageing. Using sunscreen helps prevent elastin loss.
Vitamin C: Plays a role in elastin synthesis, as it does in collagen production.
Retinoids (vitamin A derivatives): Can increase elastin and collagen production.
Peptides and growth factors: Certain peptides used in skin care products can support elastin production.
