Which is better, spf20 or spf30

In fact, spf30 is more recommended, which is also recognized by everyone as a better sun protection index.

spf30+ should be the domestic registration. In the past, the domestic regulations stipulated that spf values ​​above 30 should be marked as 30+, and PA had a maximum mark of three +s. Of course, it has been updated now, and the new sun protection registration already allows 50+ and four+. Therefore, it is impossible to judge what level your 30+ pa+++ is. The reason for this regulation is that we hope people will not blindly pursue high or low values, and only the appropriate ones are good.

spf20 pa++ can be used for commuting in winter. For commuting or outdoor activities in summer, you should choose a higher multiple. If you sweat or get wet, choose waterproof ones, and reapply them every 2 hours when outdoors for a long time.
