Colorecience Sunforgettable SPF 30 brush for a few years now. What makes it great is that it is easy to apply, is a mineral powder and has insane staying power.
You simply work the powder onto the brush and buff all over your skin. It comes in a few colors and "clear" so you pick the coverage you want. If you choose a nude color, you will love the way it gives you a bit of coverage with no cakey effect.
When the package says "waterproof," it is usually followed by a laundry list of how it is really not. Honestly, the package says "very water resistant," and it is not lying. Water, sweat, heat, nothing will get this sunscreen to budge. It is a go-to for outdoor activities and comes in SPF 50 as well for all day exposure.
It does come with a hefty price tag, but a bottle lasts forever. I have had mine for two summers now. Colorescience also has other options for sunscreen mineral powder, including a loose powder you can use your own brush with.
Yet another way to keep the redness and wrinkles away. I love how products are getting smarter and actually make you look better when using them!
