How to use sunscreen Science
1, mixing different brands of sunscreen use is harmful to the skin?
Certainly not good, at least increase the chances of skin allergies. Each brand sunscreen ingredients is inconsistent, if mixed, overlapping on the skin, may cause interference or mutually exclusive components, reducing the effectiveness of sunscreen, and even cause skin allergies.
2, for sweating more and more people, especially those who frequently engaged in outdoor activities, sunscreen is not applied to the attention of more than a few times?
Sweating more, the number should be painted up more ground. If the sunscreen with the flow away or wipe sweat, do not re-apply in time, would not mean that no sunscreen?
3, the weather should be how many different SPF value of sunscreen products?
Usually: SPF15, PA + The following is enough. Travel: SPF15 ~ 30, PA + + can. Swimming: SPF30, PA + + +, and sunscreen must be waterproof type. Of course, this is not absolute. In particular, this year, this limit is broken. This sunscreen is characterized by "high-expansion also still light and not greasy, although the sun light but have a good effect." Such as Lancome, Biotherm, silk and others have such high quality sun protection products.
4, who are a little heavy fine hair, use sunscreen every summer, will, after the phenomenon of sensory hairs have increased, especially in the face, a bit worried, want to know what the reason is, is not a hormonal thing or what chemical?
If you feel the hairs on increasing every year really should pay attention to, but not necessarily the reason for sunscreen, but we must remember, any time you use skin care products should be selected brand-name products, brand names does not mean expensive, but a symbol of quality, guarantee the safety of the skin. Like Oil of Olay, L'Oreal brands like, do not look cheap, but it is well-known international brands, quality must be good, like hormones, chemical ingredients are substandard will not add to the products. 5, sunscreen and suntan lotion are the differences? What kind of skin should choose what kind of product? Use sunscreen or suntan lotion should be determined by the skin. General suntan lotion for dry skin, and sunscreen for normal or oily skin.
6, the higher the SPF value of sunscreen products, on behalf of the stronger sunscreen or sun longer?
Should be said that both sides have. SPF blocking UVB ultraviolet rays, in general SPF15 to block 93.3% of UVB ultraviolet rays, while SPF30 would be able to block 96.6% of UVB ultraviolet rays; SPF value of the difference between 15 to 30 doubled, while the UV blocking ability of only 0.3% difference, very limited; and for PA, the general PA + effective protection time of 4 hours, PA + + for effective protection time is 8 hours, but if often sweating, even PA + + +, still have to re-apply for.
7, Cream and sunscreen What is the difference?
Only SPF sunscreen, and Cream in addition to sunscreen, ingredients will be added in antioxidants, vitamin whitening ingredients or components. Cream's greatest achievement is to resist ultraviolet light to skin damage caused, but also isolate the dirty air, dirty things, to reduce free radical damage to the skin. If you are a family office, but the way to work and meet the sun, you just rub some Cream, and no need to apply a layer of sunscreen; If you go out to play or to the beach to enjoy the "feast of the sun", it is certain To use the high-expansion of the sunscreen, the skin was safe.
8, I heard Cream painted finish will wash off after three hours, or else it will result in pigmentation, is it?
Cream should not contain ingredients in the composition caused by pigmentation, nor should the formation of pigment spots, unless you buy a substandard product.
