To keep your skin healthy, without giving up the pleasure to enjoy the sun and get a nice tan, need not so much: do not stay in the sun for too long;avoid it in the hours of maximum solar activity and regularly applied to the skin sunscreen.
times when rich tan was considered a sign of health, passed .Today it is known that excessive dose of solar radiation, disrupting the system of natural protection of the skin from ultraviolet radiation, can cause a variety of skin damage at the cellular level: sunburn, allergic reactions, premature skin aging, age spots and most dangerous consequence - cancer.
However, sunlight contributes to the improvement of health, improves immunity.Under the influence of the sun in our body promotes the synthesis of vitamin D, which is important for healthy bones and teeth, and produces the hormone of happiness - seratonin, making improves mood and depression disappear.
Alpha and beta rays
Earth's surface reaches only two types of ultraviolet rays alpha and beta type.In
UV rays contribute to beta-compaction of the epidermis (stratum corneum).The resulting cells under this layer, the protection is obtained.Beta-rays stimulate specific cells in the epidermis (melanocytes) to facilitate the formation of the pigment.Formed with the melanin gives the skin a dark shade and protects the deeper layers.On the other hand, beta rays damage the cell walls and cause sunburn.
Long alpha rays (90-95% reaching the Earth's UV radiation), in contrast to the beta rays are not warm, and we are not feeling the effects of them.They do not cause burns, but penetrate into the deeper layers of the skin, provoking an increased sensitivity to the sun and skin aging, and reducing its immunity.Alpha rays are able to penetrate even through the glass.
What to choose?
- Sun Milk often used for the whole body.Its constituent components allow you to use a very high SPF.
- sunblock is used mainly for the face.Sun filters included in almost all of the usual day cream.
- a tendency to acne preferable to use the gel without the fat and emulsifier additives.
- oils are used to enhance tanning.They are recommended for those who tan quickly and without any problems, that is actually never burns.
- To protect hair use products for the care and styling that contain SPF.
- sun protection factor (SPF) - one of the main characteristics of the tanners.The higher it is, the less tan initially, but is distributed more evenly and lasts longer.Protection Success depends not on what you apply a layer of cream.The main thing that it was enough to form a solid film on the skin.sun blockers are considered protectors, which have a protective factor of at least 10 due to the high proportion of pigment content.These creams are recommended primarily for people with light sensitive skin, as well as those who are engaged in, such as windsurfing or interested in alpine hiking.
- Sun products last generation combine two functions: absorption of UVB-rays and reflected rays UVA .If you use the old workings, it is better to combine them with new ones.
- period, when the skin is able to protect itself, called the time of self-defense (burn threshold Sun) .Depending on the skin type, this period may be quite different.sun protection factor (SPF or IP) of a tool shows how many times longer, causing it means you can stay in the sun without fear of burns.
- In determining the SPF can not account for the specific conditions : effect of UV radiation, the frequency of sunbathing, the intensity of sweating, presence of contact with water, sand, beach towel.Therefore, when calculating necessary for you SPF you need to use common sense and pay attention to the additional properties of creams, such as water resistance (waterproof).Waterproof funds through a special water-repellent components effectively protect the skin even after an hour of being in the water.Standard time of their action - 80 minutes after the race.
- Apply sunscreen to dry skin 20 minutes before sun exposure - carefully, evenly, until completely absorbed.At least every 2 hours, repeat this procedure.Do not forget the neck, earlobes, armpits.Use sunscreen lipstick and a special oil for hair.
- After taking sunbath skin needs extra moisture and fat .Means for the care of irritated skin after sun soften, moisturize and soothe it and perform another function - they do tan more resistant.Apply their need after taking a shower.
- If you are enthusiastic and your skin burned , use balms from sunburn.They soothe burnt skin, soothe irritation and moisturize.
- peeling skin after burn in any case can not substitute for a short time even under the rays of the sun - it was too delicate and sensitive.Again, you can soak up the sun only a few weeks later, when the skin is completely healed.In this case be sure to use a cream with an SPF of not less than 25-30.And remember that the risk of skin cancer increases with each new burn.
