Held Up Great in the Mexico Sun — No Burns
Size: 6 Fl Oz (Pack of 1)
I brought the 365 by Whole Foods Market Sport Mineral Sunscreen SPF 30 with me on a recent trip to Mexico, and it performed really well. We spent a lot of time outside in strong sun—beach, pool, walking around—and this sunscreen held up great. I applied it as directed and didn’t get burned at all, which is always the real test for a sunscreen. It goes on fairly easily for a mineral sunscreen, and I like that it’s water resistant for up to 80 minutes, which makes it great for swimming or sweating. It stayed effective even after being in and out of the water. The lotion also didn’t feel overly greasy, which is something I appreciate when using sunscreen throughout the day. Overall, this worked exactly how I hoped it would. If you’re looking for a reliable mineral sunscreen for travel, beach days, or outdoor activities, this one definitely gets the job done. I’d use it again without hesitation.
