It is important to be aware of the health of your skin all of the time especially if you are exposed to the sun regularly now or in the past. Those who have fair skins must be more cautious for they are the ones who are more prone of being affected by the harmful rays of the sun. Sun damage to the skin presents inself in the form of age spots, liver spots, actinic keratosis, seborrheic keratosis and skin cancer. Seborrheic keratoses are harmless, however they can be similar in appearance to melanoma so it is important to make sure you have any unusual or new skin lesion checked by a doctor or dermatologist to confirm it is benign.
The reason why the skin gets tanned when exposed to intense heat of the sun is to protect itself by producing melanin. The formation of melanin varies from one person to another. This is the reason why some people have their skins darkened faster than other people. Your location like the type of your skin are factors that affect the level of skin darkening. The nearer you are to the equator, the closer the rays of the sun are and the more damage they can do.
Creams formulated for sun protection are utilized in different ways to guard the skin. Most of the sun protection creams available in the market have both physical and chemical sun filters and others have either.
The rays from the sun are absorbed by these sun filters as the skin is being gone through. The harmful rays from the sun no longer pass through the deep layers of the skin because of sun protection creams. Damages are resisted through the chemical filters protecting the skin. The physical sun filters, on the other hand, works by means of laying a thin membrane that bounces off the damaging rays from the sun.
Ultraviolet type A (UVA) rays and ultraviolet type B (UVA) rays are guarded from trespassing the skin by the sun protection creams. The more popular term for these sun protection creams is broad spectrum cream. The damage done by ultraviolet type B rays affects the burning of the topmost layer of the skin that may lead to skin cancer. For the ultraviolet type A rays, they do not burn the skin but they can penetrate it.
The ability of the sun protection cream is measured by the acronym SPF meaning sun protection factor. However, applying a sunscreen with a high sun protection factor should not let you stay in the sun more because doing so will only lead you to being exposed to more UVA rays. When buying a sun protection cream, you must count on your skin type. A sun protection cream that has an SPF 15 is most manageable for many people.
