Summer has already arrived. beach vacations are coming up and it's time to think about protecting the skin from the sun's harmful rays.
Until recently, it was believed that the higher protection factor a sunscreen has, the more the skin is protected. However, new technologies in making sunscreens disprove this.
What should we know when choosing a sunscreen?
The best beach oil, lotion or cream should explicitly contain substances protecting the skin from both types of sun rays - UVA and UVB.
Until a few years ago, B-rays were considered a major risk factor for skin cancer. Accordingly, the technologies for preparing sunscreen lotions were directed in this direction.
Today it is no longer the case. Research shows that ultraviolet A rays (UVA) also increase the risk of skin cancer. They do not cause sunburns, but they penetrate deep into the skin, which causes aging and wrinkles.
According to researchers, about 90% of skin changes associated with aging are caused by prolonged exposure to UVA rays.
How to choose the right sunscreen for you?
Clearly, most people will turn to broad spectrum products combining protection against both types of UVA and UVB rays.
Other important ingredients that a good sunscreen should contain are benzophenones (oxybenzone), cinnamate and cinoxat, sulisobenzone, salicylates, titanium dioxide, zinc oxide, avobenzone and ekamsul.
Useful: If you chose a sunscreen with factor 15, it means that after applying it, you will burn after about 150 minutes. Why is this happening?
Because if you normally burn for about 10 minutes without a protective cream, this number is multiplied by a factor of 15, which means that you will burn after 150 minutes in the sun.
If you choose a sunscreen with a higher factor, the allowable sun exposure increases as time goes on.
Note that a higher factor does not mean the protection is double.
