Thickening and Thinning of the skin

Ultraviolet rays can cause thickening as well as thinning of the skin. Usually, on the back of the neck the thick skin is found in the form of rough wrinkles that do not vanish even when the skin is outstretched. Yellow discoloration of the skin, coarse wrinkling are often studied under a condition known as solar elastosis. Ultraviolet exposure also causes thinning of the skin that leads towards skin tearing, fine wrinkles and easy bruising.

Changes in the skin’s blood vessels

Walls of blood vessels in the skin become thin because of ultraviolet exposure and this thinning leads towards bruising just with little disturbance in sun-exposed areas. Most of the bruising that occurs on sun-exposed skin takes place on the areas like backs of the hands, forearms, neck etc. Telangiectasias or appearance of the tiny blood vessels in the skin particularly of the face skin is another cause of ultraviolet radiation.
