Sunlight contains ultraviolet (UV) lights.
These lights are responsible for wrinkles, pigmentations, sunspots and destruction
of the underlying supporting tissues of skin, thus changing the texture and
elasticity of the skin. In short, it is one of the main causes of aging of our
skin.
In fact UV light is so strong that not only
does it affects the epidermis and dermis, it also penetrate deep into the skin
to affect the blood vessels and sweat glands of the skin.
However, not all people are equally
affected by UV light. Patients with lighter skin tone will be more affected by
UV light as the skin contains less melanocytes compared to patients with darker
skin. Hence, patients with lighter skin should be more meticulous in protecting
themselves from UV lights i.e. be religious in applying sunscreen an use a
sunscreen with a higher SPF factor. Wearing long sleeves shirts, summer hat and
sunglasses are also important to protect yourself from the sun.
