As a result of misconduct on the beach comes the artificial aging of the skin, and the whole organism. Fans of excessive tanning look much older than his age, but most importantly - put themselves at great risk due to irradiation with ultraviolet light. Over the past forty years, the number of cases of melanoma in women aged 18 to 39 years old increased by eight times. At the same time, according to Medical Xpress, people still have not learned how to use a sunscreen cosmetics.
Scientists Drexel University in the United States denied the popular beliefs about protecting the skin during tanning.
The higher the SPF, the better sun protection
Very often you can hear the opinion that it is best to protect skin from the sun means with the highest SPF-factor. But US scientists believe that the difference between the figures that represent protection factor, not so great. For example, a sunscreen with SPF 15 protects against 93% penetration of sunlight and cosmetics with SPF 50-60 - 98%. Thus all sunscreens protect the skin only from UVB-rays penetrate the epidermis and protect from UVA-rays, a much more aggressive and reach the deep layers of the dermis. Experts recommend to apply sunscreen every 2 hours, irrespective of the index SPF.
With sunscreen can have nothing to fear
It is believed that the broad spectrum of action can save all types of ultraviolet rays. But as mentioned above is not the case. At least, until last year the manufacturers of sunscreens were not required to verify their product's ability to protect against UVA-rays, the most destructive to humans. In the US, only going to adopt the rules under which manufacturers will be required to demonstrate the ability of their products to protect against UVA-rays.
Waterproof cream does not require the application after each bath
In the US, on the packaging tools do not write that they are water-resistant, since in reality there is no one fully water-resistant sunscreen. All means to protect us from ultraviolet radiation, have a limited validity period - from 40 to 80 minutes. Therefore, after swimming the cream must be re-applied to the skin - immediately wiped with a towel.
In cloudy weather, no obgorite
Actually cloud passes the lion's share of UV radiation - 80%. Therefore, to get a dangerous dose of radiation possible and in cloudy weather. American doctors recommend using a sunscreen with an SPF of at least 15, regardless of the weather.
Dark skin do not need sunscreen
People with dark skin are actually less sunburn. However, although Caucasians, melanoma is much more common, fatal, she ends up mostly in African Americans. Studies show that three types of skin cancer (basal cell carcinoma, melanoma and squamous cell skin cancer) are most common among Hispanics and blacks. Moreover, they have in most cases the cancer manifests itself at a later stage, which once again confirms the need for funds while sunbathing.
Sunscreen should be "closer to the sun"
The most common misconception of women - is applying sunscreen on top of the basics, because they mistakenly believe that it should be "closer to the sun." In fact, sunscreen correctly applied daily to clean skin before using moisturizer or cosmetic.
The fight against pigment spots
Hot sun provoked pigmentation, but to fight with the pigment in the summer it is not necessary, because it is fraught with aggravation of the problem. In the summer, it is necessary rather to prevent the emergence of new age spots, using creams with a protection factor of 20, 30, some of which contain bleaching agents, but no more. No invasive procedures - peeling, grinding, dermbrazii and so on. A number of drugs - some antibiotics, hormones - increases the photosensitivity of the skin, so they should also be abandoned or replaced by others.
Botox before holiday
Some patients ask for cosmeticians directed Botox injections before the trip to the coast. The sun has to squint and blink, so that compounded wrinkles. Injections botuloktoksina protect against such trouble. Although doctors do not object to this procedure, warn -effect will not be as long lasting as usual.
To avoid all the negative effects of tanning, scientists recommend to observe a number of rules:
- Apply sunscreen 15-30 minutes before tanning cream to absorb into the skin,
- Sunbathing before 11 am and after 16-17 hours, since at this time the sun's rays are most active, it is best done in the shade
- Wearing wide-brimmed hats and sunglasses
- Drink plenty of clean water or natural fruit compote from the sun during the procedures.
