The sun is the most important element of the ecosystem and has incredible properties, but it may be harmful to humans. Excessive exposure to sunlight can cause several problems to the human body. Here you will see how we can protect ourselves by using a sunscreen and in general what applies to solar protection creams and lotions.
- What exactly is the SPF found on sunscreens?
For starters when someone is overexposure to the sun you can see that there is skin redness that is basically irritations.
The SPF index shows how much exposure to the sun a normal skinned person can have and to try to avoid these stimuli to occur.
This essentially tells us that it is better to use suncream than not to use one at all.
- Is it true that the application of sunscreen should be done a while before I get out in the sun and what is the recommended interval?
It is absolutely necessary to put the cream on the skin long before you expose yourself to the sun!
About twenty minutes is enough for the skin to absorb the sunscreen. But it is necessary to reapply sunscreen on your skin at regular intervals.
- If I get the highest possible index, I can sit in the sun as much as i want without fear?
This is not applicable to all population groups. It usually refers to people with some skin sensitivity, or small children. An average rate of protection is that of around SPF 30, which generally covers the average population. There is however something which we can not really rely on. A sunscreen lotion will not protect us if sun exposure is frequent and for long periods and neither will it help maintain the freshness of the face.
- Which is better? Sit in the sun with a high SPF lotion or sit in the shade with no sunscreen?
Even if you sit in the shade, the sun has the ability to penetrate certain surfaces. Even if you think the sun will not reach you, we will certainly affect your skin to a small extent.

- If I am not at all on the beach sunbathing but swimming do I still need sunscreen lotion?
Yes you do, even in water you must use sunscreen because the sun can more easily reach you and you will probably not even feel it until it is to late. The reason is that the sea water cools you down and you do not feel that burn by the sun, also the water does not filter the sun's rays, so use sunscreen lotion.
