What You Need To Know About Sun Protection Cream
It is important to watch out for the health of your skin all of the time especially if you are exposed to the sun. The adverse rays of the sun are responsive to those who have fair skins rather than those who have dark skins.
In the first place, you have to know why the skin gets darker when staying in the sun. When exposed to the sun, our skin produces melanin to protect itself, which is what we know as a sun tan but is actually your skin’s natural form of protection. There is a unique formation of melanin for every person. There are some people whose skins get tanned more intensely than any other people. Skin tanning depends on where you are and what skin type you have. The nearer you are to the equator, the more you need to protect your skin from sun damage.
Sun protection creams work in various ways for the protection of our skin against the harmful rays of the sun. 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. This best describes the chemical filters that are incorporated on the sun protection cream. 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.
Sun protection creams are helpful in protecting the skin against ultraviolet type A rays or UVA rays and ultraviolet type B rays or UVB rays. These sun protection creams can also be broad spectrum sunscreens. The topmost layer of the skin is burnt by ultraviolet type B rays which eventuate to damage of the cell and changes that can lead to, age spots, liver spots, actinic keratosis and ultimately this sun damage can lead to skin cancer. Ultraviolet type A rays, on the other hand, do not burn but they go through into the skin which affect aging.
The acronym SPF refers to sun protection factor which measures the strength of the sun protection cream against harmful UVB rays. But then again, it does not mean that you can go out in the sun for longer with higher SPF because it can lead to the invasion of UVA rays. You must first consider your skin type when buying a sun protection cream. Most people can manage application of sun protection cream with an SPF 15.
