How to protect your skin from the sun?
Use a sunscreen!
When choosing a sunscreen, pay attention to include protection against UVA and UVB radiation.
SPF is the most commonly used indicator of protection against UVB radiation, i.e. protection against burns (erythema). The highest SPF factor available on the market is SPF 50+
PPD (IPD or PA) are indicators defining the degree of protection against UVA radiation. Unfortunately, the rules for the use of these markings are not unified and unambiguous as in the case of the SPF. Most often you can meet symbolically the effectiveness of protection in the form of "+" or "*".
Remember! There is no cosmetic that protects the skin 100%.
In sun protection it is also important what filters have been used.
There are 2 types of filters
Mineral (physical) filters are compounds that have the ability to reflect solar radiation. Ideally suited for people with sensitive skin, vascular skin or for children, because they are well-tolerated by the skin, do not sensitize and do not irritate it. They protect against UVA and UVB radiation. In this group, there are two components: zinc oxide and titanium dioxide.
Chemical filters are compounds that act on the principle of absorbing solar radiation and converting it into safe thermal energy. They protect the skin against UVA and UVB radiation. It is a large group of compounds with complex chemical names. Example: Ethylhexyl Salicylate, Bis-ethylhexyloxyphenol methoxyphenyl triazine (tinosorb S)...
More effective sunscreens are those that are a combination of mineral and chemical filters.
