With the beginning of the summer season it is good to prepare the skin so that the tan is not harmful and aggressive. By choosing the sunscreen (including sunscreen) with protection factors (spf) most appropriate for our skin, we ensure that we can spend a quiet summer, without sunburn or trauma, but only with the pleasure of feeling fitter.
Solar products are cosmetic products designed and used to protect the skin from the action of the sun’s rays. The pigment responsible for tanning, that is, melanin, is in fact able to assimilate a large part of solar radiation.
However, following prolonged exposure, the endogenous defense mechanisms are no longer sufficient to defend the body from damage from the sun or artificial radiation, depending on the situation.
As a consequence of what we have just said, the relevance of the use of adequate solar products to protect the damage caused by exposure to ultraviolet light, whether natural or artificial, arises clear.
The assembly of solar products involves a large number of ingredients. Some may be delimited as “active” as they are capable of exercising specified activities once applied to the skin. Others, on the other hand, could be defined as “excipients”, since they are used to allow the implementation of the formulation and to ensure its maintenance over time.
The ingredients that practice the effective protective action from UV rays are the so-called sun filters. But, it is not unusual that the terms “sunscreen” and “sunscreen” are often used synonymously to designate all those cosmetic products aimed at skin application in order to protect the skin from damage caused by UV rays.

Although a product may be unalterable to water, there are no completely waterproof formulations. When it comes to questions about how much sunscreen to use, there is an answer to those as well. Many experts suggest applying a cream measure equivalent to the size of a ping pong or golf ball so to speak.
