White color of the small number of black people themselves, even if the sun to the sun will not be too dark, but very sensitive to ultraviolet light, if the color flushed like a minor burn-like, this situation repeated continuously, then president of a fine grain, black spots, freckles, skin would be premature aging. So rub sunscreen product is also wearing a hat is the correct approach.
The proper use of sunscreen products?
Theory SPF35 sun protection products, the effect will be good. Is extremely sensitive to the sun as the white matter for people of color in the sunlight exposure 10 hours no problem. However, some products will be in contact with water or sweat from falling, and each person and do not have a coated, non-wife hold soil on the surface figure. High-value products that can not be taken lightly, even if the value is relatively low, as long as supplemented coated every 2-3 hours, then sun is also a good effect. The best choice for the foundation with the whitening effect of sunscreen products.
SPF value should be the ideal number?
If it is a normal day, leave for school, work, then the election SPF10, PA + products can be. If the outdoor sports, should the election SPF10-20, PA + + products. If it is to the beach to play, or early spring skiing will take exposure in the sunshine, then select SPF 50 + is more than one product line in the equatorial regions have a need for bar!
In addition to the face, the body also painted the most easy to forget the site, such as behind the neck, shoulders, knees, back, feet, etc.. Skiing venue highly reflective, chin to the neck area most vulnerable to sunburn. Once the skin around joints skin sunburn, and when you will move about the pain, do not be negligent.
Sun can be said is the most basic maintenance work, as the aging of the skin associated with UV rays 100%! And the sun is not so much focus on the level of sun protection factor, regardless of the season and age, every day use, in order to truly achieve the purpose of sun protection.
For most people, buying sunscreen when you always think that the higher the SPF the better, dermatology Wuying Jun said that, in fact, SPF is only a reference number, in fact must also be in accordance with individual's skin, sun reactions, skin color, activity status of and sweating conditions to consider, in general, routine and preventive maintenance as long as the choice Asians SPF SPF 15 or so there, because SPF15 indicated that they could block 14/15 of UVB, or 93.3% of UVB; even SPF30, blocking only 96.6% of UVB, is not much difference.
As for the PA value is 1996 was only recognized by the Japanese Cosmetic Industry Association, "anti-UVA measurement standards" to "+" the number of distinction grades, PA + table effectively, PA + + table quite effectively, PA + + + table is very effective.
Generally more by the physical sunscreen ingredients zinc oxide, titanium dioxide, and chemical UV absorbers, made of scattered agents, physical sunscreen compared with the more modest but more content heavy, easy to block pores; while chemical sunscreen agents while more refreshing , but they easily lead to allergies. On the other hand, the higher SPF sunscreen ingredients contained in the more vulnerable not only to cause pore blocking, oily skin will feel uncomfortable, because the burden of an uncomfortable feeling caused by the use of a decline in willingness to use every day do not like or do not rub enough volume, but to make sun protection greatly reduced.
In addition, some consumers may think that as long as the multi-coated few sunscreen SPF values and the mean PA value is also followed by multiplication, in fact, is a misconception, because there was no re-apply several times, their effectiveness is the same. In addition, the current type of sunscreen is almost cover a variety of maintenance procedures, including latex, Lipstick, Foundation have joined to the powder sunscreen ingredients, but can be Do not think that painting a different sunscreen SPF values and PA values will be followed by the sum, but in the highest coefficient of coated products prevail.
Correct concept is that no matter indoors or outdoors, perfect sun protection measures are not blindly increasing the height of sun protection factor, but with the loss of sweating and wiping at any time to add sunscreen in order to achieve the best protection from the sun.
