Sun Protection Factor (SPF), determines the height of the sunscreen. The highest, 98 percent. effective protection against excessive sunlight is guaranteed by creams with SPF 50.
We usually use creams with a filter before sunbathing, we forget that we should apply it to the body before exposure to the sun, also during walks or gardening.
Correct application
The preparation should be spread on the nape, neck, arms, back, legs – especially from the knees to the feet, but also the nose, ears and mouth, which are very often overlooked by us. Remember to use creams specially dedicated to it, preferably with the highest possible SPF, because the skin in this place is directly exposed to UV rays. The cream layer should be renewed after contact with water or after two hours. This is justified because in the meantime the cosmetic wears off and we are not sufficiently protected.
The amount of application of the cosmetic on individual parts of the body varies. By saving milliliters, we run the risk of sunburn and skin melanoma – when used in scant amounts, the protection provided by the factor decreases by up to 30%. In the interests of optimal safety for us and our children, let’s properly apply 2 milligrams per square centimeter of skin. A clever trick is to apply the amount of cream equal to a small spoon on individual parts of the body.
How to choose the SPF factor?
If you are the owner of a typically Slavic beauty, the tone of your skin, hair and eyes is light, get the SPF50 sunscreen. SPF30 is recommended for brown-haired and brunettes with dark skin and brown or green eyes. with SPF15 filter.
Filter specifics
creams they are not resistant to contact with water or sweat – if excessive sweating is your problem, it is worth considering chemical filters. They are much more comfortable to use and more durable, they don’t wear off so easily, they don’t leave a “whitening” effect on the skin. They combine with clean skin after a quarter of an hour after application. An additional advantage is that after applying makeup after this time, this type of cream still protects us. After two, maximum four hours, we repeat the application, first removing the make-up, as the factors decompose.
While mineral filters they don’t stick to the skin. They work by reflecting UV rays, unlike chemical filters they must be the top layer and do not require re-washing and applying make-up each time you spread. Unfortunately, mineral filters protect us from UVA rays less than chemical ones.
Currently, not only creams contain SPF filters. We also have balms, milks, foundations and even hair care cosmetics with SPF filters. Want to know more? meet – SPF – Cosmetics with sun protection
