Doesn’t stain clothes and lightweight
Something that always bothers me about sunscreen is how it stains clothing. I did not have that problem with this sunscreen. It was lightweight. It only had a very mild gritty feeling after having it on for over 8 hours and sweating a ton. Best sunscreen out there right now!

The only sunscreen that does not break me out!
I have oily to normal skin with general sensitivity. The breakout-free Neutrogena sunscreens are the only ones that don't break out my face and body, even with reapplication. I have repurchased several times and highly recommend. There is only a slight white cast left over but here's my hack for no whitecast: apply a small amount to fingers and rub to warm, pat to cover face, then rub to blend in, then repeat with another layer. Perfect for underneath makeup, I usually put it on before primer.

Less White Cast
A little of this sunscreen goes a long way and when not slathered on, the white cast is minimal if at all. If I reapply every two hours—as instructed by every sunscreen label I have ever read—the white does become more visible by the third or fourth application but I combat that by mixing with a sheer moisturizer. There are times when I see white lines on my neck because of the sunscreen, so I just rub those in and they re-dissipate. Also, this sunscreen is noncomedogenic, oil-free, and as an added bonus, is rated at 2 in EWG’s sunscreen guide.
