Although it’s a job you can’t ignore all year round, “sun protection” is an essential skill to prevent skin aging.
What else do you need to know besides what SPF and PA mean?
Wearing sunscreen every day is not enough.
Only by using it correctly can you avoid becoming a black carbon beauty. 1. The higher the SPF and PA, the better?
Even if someone explains what “SPF” is every year, I’m sure girls will forget it after a year!
SPF is a “linear measure of UV resistance,” and the number stands for “delayed UV sunburn.”
In general, spf50 sunscreen provides up to 98 percent UV protection.
If you do, it may cause a burden on your skin, so sunscreen with an SPF of more than 50 is not recommended.
2. The thicker the sunscreen, the better?
No matter how thick the sunscreen is, the effect is the same.
If you want full sun protection, your best bet is to choose the right sunscreen for you.
Not too thick, but not just a thin layer.
The MOST IMPORTANT THING is to wipe 30 minutes after going out, wipe again every 2 hours, so sunscreen can be completely absorbed, achieve sunscreen effect.
3. Need to reapply sunscreen?
Most sunscreens on the market today contain sunscreen.
As long as the labels say “SPF” and “PA”, there is no need to wear sunscreen.
But if you don’t add sunscreen, it’s just a moisturizer that smoothen dry skin and helps with makeup.
The latest market dynamics at any time to see, please pay attention to.
