UV, UVA, etc. types of rays that we submit our skin are varied and distinguish them is important (or almost vital), especially when it comes to protect us from them and choose the appropriate photoprotection. Let’s see what son:
* grape: are the most common, approximately 90% of the Sun’s rays are of this type. To them we owe rapid tanning, but they dehydrate the skin, they have great capacity for penetration, so that they reach the connective tissue.
This makes them especially dangerous, as they age the skin prematurely are also guilty of the solar intolerances, and their damage is cumulative. They pass through without any problems the Crystal and the clouds, so that even if it is cloudy continue acting. * UVB – belong to the same group of ultraviolet to the grape, although they are less common, as soon as they reach 10%. They cause the indirect or late, moreno that appears after a few days. It acts especially at lunch time and although they are effect is more superficial, they are very intense and responsible for the most serious burns, not to mention the enormous amount of radicals that they release.
* UVC: the most dangerous of all, although in theory not cross the ozone layer, then this absorbed them, provided it’s not too fine.
* Infrared: are that more heat produced and therefore also dilate vessels (especially recommended for the hypertensive) site
Solar creams only protect in principle of the UVB rays, therefore it is advisable to seek protection for the UVA rays and radiation factors infrared.
