Useful and necessary sunscreen

With the arrival of warm days and a bright sun allwe want to get a beautiful and even tan, which looks so gorgeous on a woman's body. However, everyone knows that we are exposed to harmful UV rays, so you need to help your skin and use sunscreen.

Its main function is to protect the skin fromharmful solar radiation, so we should always pay attention to the fact that the tube showed the SPF-factor. One unit of this indicator corresponds to 15 minutes of safe exposure to the sun, therefore the more the figure indicated on the package, the longer it can be freely in the sun.

Another sunscreen is water resistant. This means that even after your stay in the pond, whether it is a pool or the sea, it remains on the skin and continues to protect it. However, it must be remembered that prolonged exposure to water reduces the duration of the cream.

Sunscreen should easily cover the skinelastic film, as well as easy to spread out. Apply such a product best after toning and cleansing the skin, just before going to the open air.

It is necessary to know that ultraviolet raysthere are three types: ultraviolet A (the most insidious rays that do not cause burns, but have an irreversible carcinogenic effect on the skin), ultraviolet B (rays that promote the production of vitamin D and melanin in the skin that causes reddening of the skin), ultraviolet C (the most dangerous , we can say, the deadly rays that are being filtered out by the ozone layer of the atmosphere and do not reach us in our latitudes).

Going to go on vacation, many ask a question,how to choose sunscreen. Therefore, it is necessary to know that there are two main types of creams - those that screen the rays, and those that block them.

Sunscreens that screensun rays, form a film on the skin that absorbs ultraviolet radiation. However, such creams pass A-rays and effectively protect only from B-ultraviolet. It is best to use a product that contains parsol or avobenzene, effectively protecting against A and B-rays.

Blocking creams consist of finely ground mineral pigments that remain on the surface of the skin and thereby physically reflect ultraviolet A and B.

Sunscreen for children does not just containhigh index of sun protection factor: it has moisturizing substances that favorably affect the baby's skin. Also in the composition of children's cream includes hypoallergenic components that protect the delicate skin of the baby.

It should be remembered that the shelf life ofsunscreens - about six months from the time you opened the tube and began using it. It can last longer if you put it on the bottom shelf in the fridge or just in a cool place. However, if the color, texture or smell of the cream has changed, then use of such products is not recommended.

I would like to recall that the use ofsunscreen is necessary for 30 minutes before exposure to the sun. The fact is that the components that contain it, providing protection, do not start immediately. Do not rub the cream into your skin, just put it in a thin layer and give it a little time so that it absorbs. The effectiveness of the cream with intensive rubbing is reduced by 25%.

Remember, the level of protection of the cream, whichdesigned for the face, usually characterized by a higher SPF. You do not need to use body cream to protect your face - this can cause redness or irritation of the skin, but you probably will not achieve the desired effect.

Even if you apply sunscreen on your skin, it is recommended to stay in direct sunlight for no longer than one hour. Be sure to use a hat and drink plenty of fluids.
