If you are a person who doesn't often go outdoors, then those below SPF30 can meet the demand;

If you see SPF30 or above, such as SPF50, and it is not high-end goods, you should be careful, because the Ministry of Health stipulates that SPF30+ can only be printed.

But besides SPF index, PA index is also very important. PA refers to the ability to resist UVA. If there is PA, the more+signs, the greater the resistance. And you must know how important it is to resist UVA. Our sunburn, wrinkles and skin oxidation are the main culprits. UVA has a strong penetrating power, and it exists in rain or shine.
