With summer, the skin faces factors such as heat, sun, chlorine of pools, sea salt, dehydration, etc..It is time to protect it and take care of it to keep it healthy and far from these aggressions.
Of all, the sun plays a double role.On the one hand it can be an excellent ally because it gives us vitamin D for bone reinforcement, but it is also the main “aggressor” of our skin because the cell damage of solar burns that appear in early ages can have serious consequences in the future.
As the Spanish Academy of Dermatology and Venerology (AEDV) recalls, the cutaneous cells oxidize and its nuclear material is damaged, an injury that persists and that the skin is responsible for remembering over time.
During the summer months, and especially in the central hours of the day, it is very importantthat plays a determining role in the development of skin cancer and premature aging.

Avoid solar burns is essential because the risk of melanoma in adulthood is doubled if during childhood or adolescence (in the first 20 years of life) burns have suffered.From the European Euromelanoma campaign, experts remember that the damage caused by the sun on the skin is permanent;Although burns disappear, the changes suffered in the skin remain, even if they are not visible.
According to an investigation published in Journal of the European Academy of Dermatology and Venerology, 88% of the people surveyed are aware of the risks of developing skin cancer when they are exposed without protection.However, four out of ten people do not protect themselves from the sun properly (except if they are on vacation).
We must have aspects such as that, although the day is cloudy, we also expose ourselves to UV rays and that the water does not protect from the sun, although the exposure is lower.In addition, in most cases we usually go from anything to everything, without filters, to remain away from the sun's rays to the endless sun and beach baths.Prepare the skin for summer must be a progressive job.
All skin types should be protected with a broad spectrum sunscreen, which helps block ultraviolet rays type A (grapes) and type B (UVB), which cause skin cancer and contribute to aging.Although no sunscreen is able to 100% block UV rays, according to the American Cancer Society (ACS), it is important to know how to choose the best.
As Dr. Aitana Robledo, dermatologist at the Jiménez Díaz Foundation, recalls, it is advisable to use a 50+ photoprotector for the face and body, the highest possible."The SPF or sun protection factor is the protection time we have in the face of exposure to rays," he explains.
Most recommended that the SPF is broad spectrum.This means that it protects us from all types of solar radiation: UVB rays, which are those that directly affect the epidermis, the most superficial layer of the skin and the one that makes melanin activated, responsible for the fact that theskin bronhes;The UVA rays, those responsible for the appearance of cutaneous aging and spots (the photoprotectors carry the word grapes surrounded by a circle; infrared protection, responsible for dehydration; protection against visible light, guilty of the oxidative stress of the skin).
The photoprotector must be applied at least 15 minutes before the sun exposure, not forgetting areas that often usually overlook like ears, lips, neckline or the top of the feet.And we will do it every two hours, or more often if we sweat a lot or get wet.The AEDV advises to apply an amount of 2 ml/cm2 or 2 mg/cm2, which would be equivalent to two fingers (index and heart) covered with cream.
Physical protection is also fundamental.In addition to the use of glasses, which must block at least 99% of ultraviolet light (UV), other accessories such as wide -wing hats or proper clothing are key.
Dark dense tissues (nylon or polyester) protects us more than cotton or linen clothes.An effective way of knowing if clothing meets its function is to “put it between the sun and us;If you let a lot of light, it is not good to protect us, ”admits the dermatologist.
In addition to clothing, nutrition also plays a decisive role in the care of our skin against the inclement summer.Vitamin C is a great help for photoprotection and allows us to fight oxidative stress.Also the nutricosmetics, antioxidants in the form of tablets, help us prepare the skin for the summer.
Other effective ways to protect ours.Find the shadow or use an umbrella if we go to the beach will help us minimize the risks because it reduces exposure to UV rays by 50%.
