sun damage

The sun has a profound effect over years of exposure on the skin, causing premature skin aging, skin cancer, and many other skin changes. Exposure to ultraviolet (UV) light from the sun accounts for most premature skin aging. Many skin changes that were commonly believed to be due to aging, such as easy bruising are actually a result of prolonged exposure to the sun.

UV exposure can also cause small white spots on the legs, backs of the hands, and arms (guttate hypomelanosis) as well as red areas on the sides of the neck (poikiloderma of Civatte).

Causes

Sun damage has the potential to be extremely harmful to the skin, increasing your risk of developing skin cancer. Exposing your skin to the sun allows both UVA rays and UVB rays to harm the skin. Over time, exposure to UVA rays, in particular, can damage the structure of your skin cells, causing the dermis to deteriorate and show rapid signs of ageing. With constant exposure to the sun, skin cells begin to mutate and die. The damage also breaks down the skin’s matrix system and depletes the collagen and elasticity levels, accelerating the speed of ageing and breaking down firmness and volume within the complexion.

symptoms

Sun damage can have premature ageing effects on the skin (otherwise known as photo-ageing). The UV rays can alter the cellular processes within the skin, detrimentally transforming them. Signs of sun damage include (but are not limited to) wrinkles and lines, dark circles, pigmentation, spider veins and broken blood vessels, redness, rough skin texture, sagging and crepiness due to a loss of collagen and elasticity within the skin

Who it can affect

Anyone who exposes their skin to UV rays will make themselves susceptible to sun damage. However, those with fairer skin types and fairer or red hair are more likely to burn, which can be more harmful to your skin and overall health
