Under the sun's rays, not all skins have the same needs. Skin tone and UV radiation levels - which are maximum in summer - determine the protection factor we need .
In healthy skins, without spots or moles (since these areas will have to protect them more), the protection factor advisable in summer according to our skin tone is:
- In light skins, eyes and light hair: SPF 50+
- In light skin and brown eyes: FPS 50+
- In dark or tan tanned skin: SPF 15+
- Lips: SPF 15
There are other conditions that determine the photoprotector that we must use. For example, if we are taking any photosensitizer medication (such as antibiotics, diuretics, anti-inflammatories, etc.) we will use an SPF 50+. In case of having a hyperreactive skin we will apply protection factors formulated with hypoallergenic physical filters. On the other hand, in the back it is preferable to use the spray format and apply it in generous amounts.
In addition, we must renew the application of the sun cream every 2 hours, as chemical filters lose much efficiency by absorbing radiation or by sweat. For the protection to be effective, manufacturers recommend applying it generously; The recommended amounts of product would be equivalent to a teaspoon of coffee for the face, and two soup spoons to distribute by the body .
How to protect hair from the sun
Our hair clears in summer as the sun destroys the pigments and / or melanin. This effect, which we may even like, has side effects that we do not like so much. In addition to leaving the hair less shiny, UV rays also damage the hair's keratin, which causes it to become rough and brittle.
So, it is necessary to protect our hair with hats or caps, and with specific capillary products.
What should we look for when we choose fotoprofector
The protection must be high-spectrum against the ultraviolet rays of the sun (UV). The SPF is a measure of protection against UVB light mainly. The number of FPS does not provide a clear measure of protection against the slightly longer wavelength of UVA. For this reason, the packaging must indicate the UVA-UVB balance (a symbol appears within a circle). This indicates that the sunscreen is compensated. In addition, it must carry both physical and chemical filters. All this information must be indicated on the labeling of the product.
Another important factor to take into account is to choose a photoprotector that, in addition to the aforementioned, contains Vitamin C and E , since they are antioxidants, anti-free radicals and will protect us from cellular damage.
