Love of beauty is the nature of every woman, everyone wants to have a whitened face, but in the heat of summer, how to minimize tanning or even sunburn? I’ll tell you a few key points: 1, pay attention to cooling. Because even if not sun, high temperatures can “bake” dark skin. Those who have more active melanin particles, even if they wrap themselves up tightly before going out, and also bring umbrellas to shade, but also can not prevent their skin gradually darkened, it is not the ultraviolet light corner to the body, but because the melanin particles in the high temperature will also be active. “So, in addition to sun protection also have to pay attention to cooling, air conditioning, electric fans can not be less.” Lu Haisan said. 2, do not eat light-sensitive food. ”Amaranth is strongly photosensitive, and people with allergies eat it after exposure to the sun, which can trigger phytophotodermatitis.” Director Pan Weili said that the same light-sensitive foods are celery, spinach, fresh mud snails, purple kale and purple cabbage. 3, do a good job moisturizing before applying sunscreen. ”Skin moisturization has a barrier function to UV rays.” Lu Haisan said, moisturizing cosmetics, there are generally three main ingredients, respectively, there are adsorption of glycerin, etc., can play a protective role of Vaseline, etc., and can moisturize the bionic material hyaluronic acid, etc.. On top of this, then smear the sunscreen to be more effective. 4, apply sunscreen 10 to 15 minutes before going out. This is because sunscreen needs some time to pass after application before it is absorbed by the skin and works. It is best to apply all over the exposed skin of your body, and don’t forget your lips (optional SPF index of not less than 15 lipstick), and every 2 to 3 hours to apply. 5, do not believe in “whitening needles”. The so-called “”whitening needle””, the composition is mainly tranexamic acid and glutathione, the former can block melanin production, the latter can accelerate the metabolism, but the use of the effect is not as good as advertised, “some are oral, some are injected. You can only shorten the time to restore the skin after tanning, and want to rely on these chemical ingredients into Snow White? They can not do.
