Black skin also need sunscreen to understand the meaning of SPF and PA
In the outdoor activities, sun protection is very important for their own protection measures, so many "ALICE" confused: sunscreen SPF and PA on the sun, I do not know how to choose. buy: Suitable for yourself is good Associate professor Yu Bing, a dermatologist at the Affiliated Hospital of Henan University of Traditional Chinese Medicine, said that SPF is the English abbreviation for the light protection factor and the long-wave ultraviolet protection class, and is an internationally accepted standard. Objectively speaking, the level of sun protection index can reflect the size of sun protection products against ultraviolet radiation. The higher these two values, the better the sun protection effect. However, it should be noted that the higher the protective factor, the higher the allergenicity of sunscreens, which can easily cause contact dermatitis, and the appearance of papules and pruritus at the application site. Generally, the minimum sun protection index of sunscreen products is SPF2-6, the medium sun protection index is 6-8, and the products in the range of SPF12-20 are high-strength sunscreen products. The products with SPF values ​​between 20-30 are ultra-high-strength sunscreen products. The following three criteria are recommended on how to choose a sunscreen suitable for your own use. For those who mainly work indoors, SPF10 or PA+ sunscreens are recommended; outdoor workers are advised to use SPF20 or PA++ sunscreens; when under hot sun and sea bathing, sunscreens with good water resistance should be used, around SPF30. , PA + + + products. Of course, sunscreens with a high protection factor have a good preventive effect against solar dermatitis, and they can prevent freckles and chloasma from deepening pigmentation. Myth: Dark skin without sun protection Many people begin to pay attention to sun protection and their skin becomes dark. They think that reapplying sunscreen is no longer useful. Experts remind you that when the skin becomes dark, dry, peeling and lack of water, it means that the skin has been sunburned. At this time, you need to take care of sunscreen products, and at the same time use some sun care products. In summer dermatology clinics, patients with solar dermatitis and solar urticaria often see complaints. They said that sunscreen is not effective for them, and use equal to no use. Experts believe that it is not useless sunscreen, but that they do not use enough dose. Many people believe that as long as you use sunscreen cosmetics, you can prevent light. In fact, this is a misunderstanding. The sunscreen's light protection effect is closely related to its actual coating amount. The amount of coating specified in the sunscreen determination method is 2 milligrams per square centimeter, and the actual survey found that most people use only 0.5 milligrams, that is, only 1/4 of the amount. When the coating amount is reduced by half, its light protection effect is reduced by 50% to 60%. This is why many people are sunburned and sunburned. Suggest: Bring a bottle of sunscreen In order to make sunscreen products really play a role in sun protection, experts recommend that you pay attention to use enough when smearing. In order to make the skin have sufficient absorption time, it should be used within half an hour before going out. Since sunscreen absorbs UV light with a certain degree of saturation, outdoor activists should carry a bottle of sunscreen with them and reapply once every two hours. It is not only the face, but also the exposed areas such as the arms and the neck. Apply a special sunscreen cream around the eyes. If the face or eyes are sunburned, cold water or ice cucumber should be used in time. Finally, emphasize that sunscreen cosmetics are not just young people's patents. Because ultraviolet rays can decompose the skin collagen and promote skin aging and wrinkles, it is more important for the middle-aged and elderly people to choose moisturizing sunscreen cosmetics.
