Favorite SPF
Size: 6 Fl Oz (Pack of 2)
This is the only sunscreen my family and I use now. We’re really sensitive to heavily fragranced sunscreens, so finding one that’s fragrance-free and still works well has been important for us.
I like that it sprays on easily, feels lightweight, and doesn’t leave us feeling overly greasy or sticky afterward. It’s become our go-to for beach days, travel, sports, and everyday sun protection.
I also appreciate the cleaner ingredient profile and that it’s vegan and dermatologist tested. A lot of sunscreens tend to irritate my skin or give me headaches from the strong scent, but this one has worked really well for our family without those issues.
Simple, effective, and one of those products we consistently repurchase year after year.

It works well, but it’s expensive and greasy
Size: 6 Fl Oz (Pack of 1)
As far as sun protection goes, this has worked perfectly for my family. Spray it on, blend it in, good to go. No sunburn. There are a few annoying things about it though. The price is incredibly high, imo. It is unscented, which is rare for sunscreen, but it smells like alcohol when wet. Also, this stuff is oily. It makes everything it touches greasy looking (hair, clothes, hands…) I like this overall for an alternative to thick mineral sunscreens. It’s pretty convenient.

Great for sensitive skin
Size: 2 Fl Oz (Pack of 1)
I have extremely sensitive skin and recently found out my skin hates the sun due to my autoimmune issues. This sunscreen doesn't break my skin out, keeps me from getting sunburnt and doesn't have a bunch of fragrance. This travel size has been perfect for throwing in my bag for a day at the baseball park or beach. This is a non greasy and no whitecast spray that has a high spf too. I highly recommend it.
