When it comes to sunscreen, having different types of SPF can make a difference in terms of how much coverage you want. The higher the number, the longer your sunscreen will last against the harsh sun and the less you will have to reapply it. The lower the number, the shorter it will last and the more the sun will start shining through to your skin. Depending on how long you'll be in the sun that day depends on how much sunscreen you should be wearing and what SPF you should go for. SwimOutlet has every type of sunscreen you can want, whether it's high or low coverage.
For SPF 25 through 50 you'll be perfectly fine for an average day out in the sun for an hour or two. This type of SPF would be great to wear if you were heading out for a run or a quick swim and you need something to protect your skin. This has a stronger formula so it will last for a longer amount of time and it will better shield you so you won't get sunburned. The 25-50 range is best suited for just a short amount of time, and if you want you can reapply more after the effects have worn off. However, always consider what you'll be doing outside before applying anything, that way you'll be extra prepared.
