On the importance of sun protection and sun protection

As we all know, ultraviolet rays are the main cause of skin aging, and the concept of photoaging skin care has been proposed many times. However, there are still many girls who do not pay enough attention to the problem of ultraviolet rays, and always neglect sun protection care for various reasons. So when a summer is over, the skin not only turns yellow and darker, but wrinkles and crow's feet also begin to increase. The skin looks very poor and the aging speed increases exponentially. If you want to retain your youthful appearance, active sun protection in the early stage and serious anti-aging in the later stage are both necessary skin care work.

How to choose sunscreen products?

A: When purchasing sunscreen products, you must read the instructions carefully, choose products with the appropriate sun protection factor (SPF value), and also find out whether the product has UVA protection function (generally speaking, products only marked with the SPF logo are not UVA protection, and must have a PA value to effectively block UVA). Only in this way can you buy the product you need.

Is the higher the SPF value, the better?

A: The SPF value only indicates how long it takes to delay the skin's exposure to UVB and sunburn. In other words, the SPF value determines how long the skin can withstand sun exposure, not the intensity of the ultraviolet rays. In other words, the sun protection ability of SPF30 is not twice that of SPF15, it just lasts longer.

What does PA+ mean?

A: The more plus signs there are, the more it can block the genetic damage caused by long-wave UVA deep in the skin. The correct name of PA is Protection of UVA-1, which means that the PA value is closely related to "sun protection aging".
