Sunscreens – All You Need to Know About Them

Although winter is in full swing, we should also be aware of the summer. Although it seems so far away, don’t let it trick you, it’s necessary to repeat the curriculum when it comes to sunscreens. We bring you everything you need to know about these preparations.


Creams with UV protection of the sun, have become a very important factor in skin care, since it can protect the skin from damage which could cause UV. Therefore, the choice of sunscreen is very important because it protects your skin from the dangers of ultraviolet radiation during sun exposure.

The UV rays every year are becoming more dangerous because of the thinning of the ozone layer and the ozone hole, which protects the earth from harmful solar radiation. When this layer is thinner, there are more penetration of harmful radiation, since our skin is not used to that kind of radiation, we need additional protection.

Prolonged exposure to the sun without protection can cause severe burns, fast aging of the skin, age spots, freckles and wrinkles. These burns of the skin are very dangerous because they can cause skin cancer, and there just “performance” sunscreen.

Calculate your factor

People can get sun burns of varying intensity, depending on the amount of melanin that has a certain skin. People who have darker skin, they need longer to get a sunburn. Because of such differences in color, produced a variety of creams, sprays and emulsions with different SP factors, which provide varying degrees of protection. In addition, it is necessary to bear in mind that certain medications can cause skin burns much faster than usual.


SP factor that is written on sunscreen indicates the degree of protection, ie, the higher the number, the longer your skin will be protected. To find out which factor should be your skin, you will need to multiply the number of minutes you need that your skin begins to blush at the sun without protection by a factor on the bottle. Represents the product of the number of minutes that you can spend in the sun, after you’ve applied sunscreen, so you wont get burns.

Which sunscreen you should buy?

When buying sunscreen, it is very important to read the instructions on the bottle and make sure that you are buying cream protects against UVA and UVB rays. In fact, there are certain creams that do not contain filters that would protect against the said radiation. Also, you can be sure the same if you buy a cream that has filters “broad spectrum,” which means it protects against both UVA and UVB sun rays. Sunscreen works by absorbing harmful rays of the sun and converts it into heat, because cream in itself has the ingredients that make it possible.


Our recommendation is to buy something more expensive and higher quality creams of well-known manufacturers. Many creams that you can buy “the action” in supermarkets and similar stores do not have strong enough filters and you will be much less protection from the sun, but some other quality cream. Also, we recommend that you buy a cream with SPF 15 and above. All lower factors will not give you enough good protection.

Strange myths about sunscreens

Many people still believe in the old stories of our parents as the sun is not dangerous, so we can not burn under your clothes, you can not burn the shade or it is enough to apply sunscreen – once a day. Unfortunately, these are all myths that just does not “hold water”.

Apply sunscreen only on parts of the body that are not covered by clothing. Unfortunately, this could not be further from the truth. People who spend their free time on outdoors, should pay special attention to take the details, such as applying sunscreen to your entire body, as has been proven many materials, especially cotton very well miss the sun’s rays.

Accordingly, the clothing will not protect against sunburn if you stay in the sun for a long time. When you’re in the shade or stay indoors do not need protection from the sun. Not only will you burn without sunscreen in the shade almost as much as you will burn in the sun, but you can easily burn and when you are indoors. The UV rays are so strong that it is very easy to go through the windows of houses and cars as well as through clothing.


Applying sunscreen once a day is enough. Fortunately, most people know this, but it is useful to reiterate that the cream should be applied after every shower time.

You should be aware that regardless of the promises that you will be one applying the cream protects for hours, it’s just not true. And the best cream will not protect you from the strongest sun for more than two or two and a half hours. By applying the cream once a day, almost the same as if he and not applied.

If you buy a waterproof sunscreen, it will protect you when you’re in the water, but they have to re-apply as soon as you dry. Also, keep in mind that sunscreen should be 20 minutes to take effect after application.

If you use sunscreen, your body will not produce vitamin D. Studies have shown that we should not spend the whole time in the sun to keep our bodies absorb

enough sunlight to produce vitamin D. The normal amount of sun protection factor, a healthy diet and activities outdoors are sufficient to keep our bodies produce enough vitamin D.
