Damage caused by the sun usually occurs in our early years before the age of 20, however, this damage accumulates and only begins to show up from the age of 35 and onwards, and progressively worsens as we age.

Without protection from the sun’s rays, just a few minutes of exposure each day over the years can cause noticeable changes to the skin. Freckles, age spots, spider veins on the face, rough and leathery skin, fine wrinkles, loose skin, a blotchy complexion, and skin cancer can all be traced to sun exposure.
Signs of Sun-damage:
Excessive sun exposure causes our melanocytes (pigment-producing cells) to become damaged and produce excessive amounts of pigment in certain areas of the skin; this shows up as dark brown spots. On the contrary, they can also cause the death of the melanocyte resulting in loss of pigment in certain areas, which show up as white spots. Together the skin can appear uneven and blotchy.
When our skin is exposed to the sun our capillaries dilate and move closer to the surface of the skin. This temporary effect allows heat to escape so the body can cool down in periods of prolonged heat. This continues action over the year’s damages those capillaries and they loose there ability to constrict again leading to a red appearance of the skin and larger capillaries can become visible.
Wrinkles and Sagging
The UVA rays that are emitted by the sun have a long wavelength and can penetrate the dermis of the skin. This breaks down our healthy collagen and elastin fibres and leads to premature ageing. This can be seen as wrinkling and sagging of the skin.
