Today, in the world there are numerous sunscreens available for everyone. It is so rampant; it has become an issue because it is hard to select the best. Parents usually buy sunscreens and keep them in the house mostly during summertime.
Most people buy sunscreen because of their family, no one would want anybody in their household to experience sunburn. This is what should be done when you get confused about which sunscreen to buy.
Check If The Sunscreen Is Board Spectrum
The sun lets out two kinds of rays, we have ultraviolet A and ultraviolet B rays. They are mostly called UVA and UVB. These rays are both bad for your skin and they can both cause skin cancers when excess.
UVA rays are mediators for early skin aging while UVB rays cause sunburns on the skin. Board spectrum sunscreens are capable of protecting your skin from both rays.
A Sun Protector Factor (SPF) Of At least 30 And Above
A sunscreen’s SPF can let you in on the amount of UVB rays coming from the sun that can be filtered out. These are the different numbers of SPF and the number of UVB rays that they can filter.
| SPF | UVB Percentage Filtered |
| 15 | 93% |
| 30 | 97% |
| 50 | 98% |
The issue is that no matter how high the SPF number is, it cannot block all the rays. To be on the safer side, a sunscreen that has SPF above 30 is said to be better and safer.
How Long Does The Sunscreen Stay Under Water
Sunscreens available on the market today have a tendency to specify how long and effective their product can stay when you are swimming or sweating. It should at least stay for 40-80 minutes before applying again.
Sunscreens usually stay for a maximum period of 2 hours before it wears off. Every 2 hours under the sun, you should apply sunscreen again. Sunscreens no longer claim to be waterproof because they all wear off with time when underwater.
