The sun, which is a necessary source of radiation for the continuation of life on earth, has many positive effects. Giving heat, making vitamin D, using it as a therapeutic in some skin diseases, and its positive effects on human psychology are just a few of them. In recent years, as a result of the thinning of the ozone layer, the sun’s rays affect the earth more and it is observed that the risk of sunburns, skin cancer formation, light-related allergic diseases and light-related skin aging increases. For this reason, there are some tricks to consider when using sunscreen;
The higher the sun protection factor of a sunscreen cream, the better it is. However, UVB protection alone is not enough. For UVA protection, the values created after special measurements should also be included in the product.
Sunscreen should be protective for both UVB and UVA. Therefore, the SPF value for UVB protection and the IPD value for UVA protection should be included on the product. A sunscreen with an SPF of 30 protects 97 percent from the sun. The effects of higher protection factors are negligible.
It should be water resistant. This is especially necessary after swimming and sweating so that the product does not go away from the skin.
It should be water-based to prevent acne formation.
It should not contain substances with a high risk of allergies.
It should be applied at least 20 minutes before going out in the sun.
The cream should be reapplied every hour when you are at the seaside or by the pool.
The expiry date of the cream should be checked, and a cream should not be used for more than 2 years.
Creams should be stored in a cool and sun-free place.
Fair-skinned people, blondes and redheads should use a cream with a high protection factor.
