1. Epidermal layers
A slower cell turnover and reduction in lipid production on the skins surface means roughness and dryness are more likely. As this particular layer of the skin ages, it becomes more sensitive to UV light. The skin is less efficient at healing itself, and a reduction in immune function can lead to an increase in skin infections, together with slower wound healing. The skin may become less resilient and feel irritated more frequently.
2. Dermal layers
After the age of 25, there is a 1% annual decrease in collagen, one of the ‘building blocks’ of the skin. Together with a decline in elastin this leads to dermal tissue disorganisation. The structure of the skin is compromised and wrinkles are more likely. Elasticity is reduced, making the skin more prone to damage and broken capillaries. Reduced blood flow means a less efficient delivery of nutrition and oxygen to the surface. This leads to a decrease in the rosy glow enjoyed by youthful skin.
