It quickly makes the skin tanned, plus the skin’s metabolic cycle is generally 28 days, and after being exposed to strong UV rays in late March and early April, sun spots will appear by May! The aging and pigmentation problems caused by UV rays to the skin determine that sun protection is one of the priorities of spring skin care. The sun can cause a lot of damage to the skin, and this is when everyone will further realize the importance of sun protection! Scientific sun protection to be fearless of the hot sun! How to effective sun protection? What is the scientific choice? Physical means – the most basic and safest Umbrellas, hats, sunglasses, sunscreen shirts and other methods can isolate most of the UV rays and play a barrier effect, but it does not completely block the sun, because there is still a part of the UV rays will reach the body and face through reflection and scattering. Due to the high reflectivity of objects such as concrete floors, it is recommended to try to choose the internal fabric is dark umbrellas, which can absorb some of the light and make people feel cool, otherwise, the light will be transmitted through the light-colored fabric to the person playing the umbrella, as if a small sun that produces heat, and does not play a sunscreen effect. Sunscreen supplies – only choose the right, not expensive 1, according to the environment in which you choose the sun protection factor SPF: that is, sun protection multiples, refers to the sunscreen products can extend the skin by the sun caused by the time required to redness of the skin times. PA: mark the standard of sunscreen products on UVA defense ability, domestic PA value is mainly divided into three levels (+, + + +, + + +), respectively, said effective, very effective, very effective. The more the + number indicates the stronger the defense ability. Long-term indoor environment, you can use SPF20-30, PA++ sunscreen. If you need to go indoors and outdoors frequently or travel outdoors, you must use SPF 50, PA+++ sunscreen. Sun protection factor is too high, easy to cause the skin burden; sun protection factor is too low, can not play a sunscreen effect. At the same time to pay attention to the full amount of use, the standard amount of sunscreen is about 2 mg per square centimeter, equivalent to the face needs a dollar coin so much volume, the amount is not enough to make the sunscreen effect plummet. Sunscreen validity is definitely not coated a tube a day, generally need 3-4 hours to reapply once. 2, according to the skin to choose the sunscreen formulations Many people think that summer is easy to sweat, but also to use sunscreen products, will make the skin more sticky, very uncomfortable. I’m afraid this is the most love-hate place for sunscreen products, but in fact, as long as you choose the right formulations, it’s not a problem. Sunscreen, lotion, spray …… There is only one standard, and that is the one that suits your skin type. Dry skin can choose a sunscreen, a little thicker texture can form a protective film to reduce the evaporation of skin moisture. The sunscreen lotion can be chosen for neutral and oily skin, which is lighter and more breathable to reduce acne formation. Special reminder of sensitive skin friends, it is recommended to use medical skin care brand sunscreen products, more safe and mild. Not easy to apply to the place can use sunscreen spray, but children’s face is best not to use, because when spraying children easily inhale sunscreen micro-particles. Some small details about sunscreen 1. Not all sunscreens must be removed. If the sunscreen back instructions need to remove makeup, then you can use makeup remover to remove clean. If the instructions are not written, then just wash it off with a cleanser. 2, if your sunscreen texture is very sticky, and you feel that the cleanser really can not wash clean, then you need to seriously remove makeup, and then take warm water to rinse clean. 3, if the texture of your sunscreen is very much like a correction fluid, and sunscreen bottle shaking, you can hear the sound of a bead, it is said to be “shake” water and oil separation type sunscreen (this sunscreen must be shaken well before use), directly with the cleanser to wash clean, do not need to use makeup removal products. 4, judge the sunscreen unloading not unloaded clean method is, if after unloading or water beads of distribution is not clean. The state of unloading clean should be: water neither condensed into a bead, nor into a strand flowing down, was evenly distributed. 5, acne skin can actually use sunscreen, of course, the premise is to choose a sunscreen that does not contain oil, no acne-causing ingredients. 6, many people ask whether it is good sunscreen or sunscreen spray, it is recommended that the formal sunscreen with sunscreen, replenishment with sunscreen spray. The reason for this is three: (1) the spray will be more or less stimulating; (2) improper use is easy to spray uneven; (3) if the thickness is not enough sunscreen effect will also be weakened. After all, the actual effect of sunscreen products is directly proportional to the amount used. 7, before going out to put on sunscreen can not protect the sun all day. If you are outdoors for a long time, then at least every two hours to reapply. 8, whether sunny or cloudy, summer or winter, be sure to do a good job of sun protection. The clouds can only stop 20% of the UV rays, you can not see the sun, do not feel the heat, does not mean that there is no UV rays. As long as there are UV rays, there is damage. Applying sunscreen is not only to prevent tanning, but also to prevent aging. After all, the UVA that can age you is maintained at a high level throughout the day. 9, isolation and all cosmetics containing sunscreen value are not a substitute for sunscreen. The amount of cosmetics used is relatively small and far from the amount needed for sun protection. Daily commute, the amount of sunscreen used is a coin. If you put a coin-sized amount of isolation or foundation with sunscreen on your face, can you still see people? Of course, coated with sunscreen is not safe to sunbathe? Not really. Long time outdoor, only rely on sunscreen (soft sun protection measures) is not enough, remember to go out to play umbrella (hard sun protection measures).
