Check your Sunscreen Products Can it prevent UVB and UVA at the same time?

Old knowledge: 365 days, sunscreen every day.

New knowledge: high protection index, broad-spectrum sunscreen and adequate dosage.

No matter how cloudy, cloudy or rainy, it is necessary to stick to sunscreen products every day. This is the most basic and important skin care course. But do not think that you have been able to block ultraviolet rays by applying sunscreen, because the latest research finds that most women have very bad habits in choosing and using sunscreen products, which results in that sunscreen products can not reach the protection of bottle labels. Effect.

First of all, please check whether your sunscreen product can prevent UVB and UVA at the same time. The SPF index refers to the ability to defend UVB, which is well known. But for UVA, the form of tagging is quite different. Most of Asia uses PA annotation, while European PPD annotation is more professional (conversion method is: PA+=PPD2~3, has a protective effect on UVA; PA++=PPD4~7 has a better protective effect on UVA; PA+++=PPD is more than 8, which has a good protective effect on UVA); Some European brands only label "UVA" instead of specific protection index. But in fact, UVA has been known as the "chronic killer of skin". The accumulation of small amounts of "long term" has caused the "lethality" to refer directly to the skin DNA. Therefore, all brands attach great importance to broad-spectrum sunscreen technology that can protect ultraviolet rays from various wavelengths. This may be one of the most important breakthroughs in skin health and perfection in recent years.

Secondly, insufficient consumption is a problem which most people neglect. In pursuit of skin comfort, prevention and follow-up Cosmetics "Rubbing", many women just thin a layer of sunscreen cream; some even give up sunscreen cream when they have acne and oil. Yan Shuxian, a department of dermatology in Huashan Hospital of Shanghai, told us: "with the habit of smearing commonly used by women, the actual protective effect usually does not reach half of the effect of product labeling." That is to say, even if you use SPF30/PA+++ products, the effect may be only SPF10/PA+. "And they do not know themselves, and they think it is very safe to bask in the sun, which is very dangerous." Wu Yan, an associate professor of Department of dermatology at No.1 Hospital of Peking University, also pointed out: "ultraviolet radiation can cause acne to deteriorate and aggravate oil production. Oily skin and acne skin actually need sunscreen. It is recommended to choose products without oil formula. And sensitive skin women, it is best to use pure physical sunscreen, although some heavy, but your safety.

Suggestion: please use sunscreen products that can prevent UVB and UVA every day for 365 days, and choose the broad-spectrum sunscreen products with high SPF and PA index as far as possible when the comfort is acceptable. After basic maintenance, apply a sunscreen product first. After more than ten minutes to half an hour, apply a sunscreen product before makeup and go out, so that the problem of insufficient dose can be solved skillfully, and at the same time, the comfort and the ability of rubbing can be reduced.

Top Tip: a bottle of facial sunscreen product can be used for about a month if the dosage is enough. If you use it for two or three months, that means that the amount of daily use is much less than that.
