 Before heading to the beach, think about what kind of protection from the sun you will use. The most common - a sunscreen that is covered by various myths and conjectures.
The next time you're thinking about your summer sun protection, remember that five well-known manufacturers of sun protection products are in their productions or that kind of protection, thereby misleading consumers about whether or not the cream prevents exposure to UV rays and can Does he prevent the development of skin cancer. All this makes you wonder: what kind of vehicle is right for my skin and what is able to protect her? We decided to seek help from the experts and get answers to the most interesting and important questions.
Myth 1: Sunscreen - is all that is needed to provide protection.
"Sunscreen - this is only one part of the component of sun protection", - explains Valentin Serov, doctor, professor of dermatology at the Medical Institute. "Applying the cream in large quantities and doing nothing, you do not let the harmful effects, since even a good means only 50 percent protects you from burning out." Also, if you decide to sunbathe between 10 am and 4 days, it is better to find a dark place because the sun is the most powerful; Close shoulders, put on a hat with a wide brim and wide sunglasses; Sunbathing should be in moderation and annually checked by a dermatologist.
Myth 2: The level of SPF protection and fighting with UVB, UVA rays and.
SPF (sun protection factor) is designed to protect only against UVB rays. However, an average of about 16 active ingredients approved by Food and Drug Administration (FDA) and contained sunscreens also block and absorb UVA rays. Among these ingredients, avobenzone (avobenzone), octocrylene (octocrylene), titania (titanium dioxide) and zinc oxide (zinc oxide), as well as the recently approved Mexoryl SX. Make sure that one of the ingredients found in your sunscreen, or choose products labeled "broad spectrum" ("a wide range") - this means that they protect against UVB & UVA rays.
Myth 3: Some sunscreens protect all day.
"Be careful to protect the SPF - sun cream should be applied every two hours," - says Serov. "The active ingredients in most products begin to break down after prolonged exposure to the sun." Only physical blockers like zinc oxide, are effective after two hours, but not all sunscreens contain these ingredients.
Myth 4: Some sunscreens are water resistant.
The FDA does not recognize the term "water resistant," so do not forget after each stay in the water to put the cream again. The organization provides "resistance to water / sweat" ("water / sweat / perspiration resistant") (which means that the product offers SPF protection after 40 minutes of exposure to water) and "strong resistance to water / sweat" ("very water / sweat / perspiration resistant ") (which provides protection in SPF 80 minutes). To stay protected, apply the cream after swimming or excessive sweating.
Myth 5: Sunscreen can provide "total protection from the sun."
"No sunscreen blocks UV rays at 100 percent," - says Serov. For example, SPF 15 protects against 93 percent of UV rays, SPF 30 - vs. 97 percent and SPF 50 holds back 98 percent. You must bring the body of two tablespoons of cream half an hour before sun exposure, so that he had time to absorb into the skin.
