Skin elasticity maintenance and factors affecting firmness

Skin elasticity, the ability of skin to stretch and return to its original shape, is maintained by structural proteins known as collagen and elastin. As individuals age, these proteins naturally diminish, leading to sagging, wrinkles, and changes in texture such as deeper folds or thinner skin.

Several factors contribute to the loss of skin firmness. UV exposure from the sun can penetrate the dermis and cause cellular damage, while lifestyle factors including smoking, dehydration, and lack of sleep can destroy collagen and elastin through chemicals and cortisol.

To improve elasticity, experts suggest several steps, including hydrating both internally by drinking water and externally through the use of lotions to keep the skin plump and moisturized.
