In fact, it is an organic compound (monosaccharide), in fact - a simple form of sugar. That's why, by the way, many tanning agents are sweet to the taste. We conducted an experiment which autosunburn is better at home.
For our skin this is a harmless substance. It penetrates only into the stratum corneum, and through interaction with amino acids forms brown pigments (melanoid). A similar reaction occurs, for example, with the notched apple left in the air: sugar and amino acids react with oxygen and the surface of the fruit darkens. The tan obtained in this way lasts 3 to 5 days, with time the pigmented skin flakes die, and as they exfoliate our body pales.
Some manufacturers also offer other products for autosunburn, the principle of which is aimed at stimulating the synthesis of melanin. They include acetyltyrosine (a natural amino acid). The advantage of this tan is a more natural color, which lasts longer. Another plus - some protection from UF-radiation (due to the development of its own melanin). Means with dihydroxyacetone contribute only to a small protection only from rays of type A, but from hard radiation of type B, the skin is absolutely not protected. Therefore, do not delude yourself: the fact that your body after autosunburn has acquired a chocolate shade, will not save on the beach from sunburn.
How correctly to use bronzants? Today they are often produced with a content of dihydroxyacetone from 2.5 to 5% and are designed for different skin types, that is, light, medium and dark. Accordingly, you can individually choose a shade. But this does not mean that a light blonde with an autosunburn will turn into a mulatto. Rather, her body will acquire an icteric color. Therefore, the main rule: choose a product in accordance with your skin type. And do not overdo it. The more cream or lotion you put on the body, the yellower it becomes.
By the way, the color does not appear immediately, but after a while, usually from 3 to 12 hours, and the maximum effect is achieved in 24 hours. The tan obtained in this way is retained for 3 to 7 days. But again, it depends on the condition of the skin and its type. Face and body before applying bronzant must necessarily be treated with a scrub or light peeling. The fact is that the stratum corneum is uneven in different parts of the body. On the palms, elbows, knees and heels - it's more. Therefore, they can become darker. Another way to avoid unnecessary "spotting" - to treat these places with cream, well, and the means for self-tanning, respectively, cause less. Or, simply after applying the bronzant, blot the "dangerous zones" with sponges to remove make-up, after having moistened them in water and wrung out.
Sometimes on the face there is a clear yellow line near the hair and eyebrows. To avoid its appearance, first apply the cream along the hair growth line. If this did not help, try removing the unnecessary yellowness with a facial scrub, lemon juice or - literally a point - light chemical peeling from a cosmetologist. And the most important advice - with autosunburn for the face all the same do not overdo it. If you often use it, then the pores inside can appear - you get such pseudocomedones or black dots.
After processing the body with bronzants, the main thing is to stand in the "image of the star" for 15-20 minutes, so that everything will dry out thoroughly. Today in the salons offer a professional procedure for artificial sunburn. It is done either with a balloon, from which a pigmentation agent is sprayed under pressure, or in special booths, where a spray is sprayed from the nozzles - and the color is uniform.
Another way to get a chocolate shade, bypassing the beach, is a solarium. But here, just like in the sun, you can damage your skin. Therefore, sessions in the solarium should start with a minimum of time in accordance with your skin type. Beating to abandon the solarium to people who have many birthmarks on their bodies, they or their relatives have malignancies, those who suffer from mastitis, gynecological diseases. Care should be taken to those who take antibiotics, antiallergic and other medications. Some oral contraceptives, for example, increase susceptibility to sunlight and can cause uneven pigmentation.
Especially for solariums intensifying tan means are used. Actually, they are sold with a note "for tanning." But at sea, by the way, it is better not to use them - they do not have a factor of protection.
After a session in the solarium, it is good to apply a cream that fixes the tan on the body. The composition of this agent, as a rule, includes marine collagen, shea butter, elastin, as well as cooling substances, for example menthol. Today you learned which autosunburn is better at home.
