Is 30 SPF Good for Sunscreen?

Yep, SPF 30 sunscreen is a solid choice and one most dermatologists recommend. It blocks about 97 percent of UVB rays, which is enough protection for beach hangs, backyard barbecues, and just about any day spent outside. It does not last longer than other SPFs, so you still need to reapply every 80 minutes, especially if you are swimming or sweating. Going higher than SPF 30 gives you only a tiny bit more coverage, so it really comes down to how well and how often you apply it. Used right, SPF 30 totally does the job.

Can You Use SPF 30 Daily?

Yes, SPF 30 sunscreen is a great everyday choice and something most dermatologists say should be part of your morning routine. It protects against about 97 percent of UVB rays and helps guard your skin from UVA rays too, which are the ones that can cause aging over time. Even on cloudy days or when you are mostly indoors, a daily layer of SPF 30 is still a good move. It is one of the easiest ways to help keep your skin healthy, happy, and feeling good for the long haul.

How Long Will SPF 30 Last?

When you put on SPF 30 sunscreen, it gives you solid protection for 80 minutes,as long as you apply it generously and evenly. After that, it starts to wear off, especially if you are swimming, sweating, or drying off with a towel. Higher SPFs do not last longer, so even with SPF 50 or 100, the 80 minute rule still stands. Best move is to put it on before you head out, reapply every 80 minutes,and keep your skin covered so you can enjoy the sun without the burn.
