I sooo wanted to love this product; however, the results were not as I expected. Especially at this price point. I have sensitive skin & actually broke out, so maybe I am allergic to one of the ingredients or applied the product too thickly. I’ve experienced better results with Coola’s Radical Recovery Organic After Sun Lotion which is only $32 for 5oz, so it’s definitely more cost effective & delivered better results in my opinion.

Could double as a sun safe Uruk-hai cosplay

Size: 5 Ounce (Pack of 1), Style: SPF 50+

This sunscreen is amazing. Was in the sun off and on all day. One thing though. Make sure you apply with a mirror in front of you or you may end up walking out the door looking like a Uruk-hai from LOTR. I was in an allfire, trying to get to the fun part of my day, and rushed putting it on. Just as I was about to leave the hotel room I caught myself in the mirror. Complete white hand print on my face where I hadn't rubbed it in well enough. So yeah, works amazing, no sunburn, and needs rubbed in well. LOL

The best sunscreen on the market

Size: 5 Ounce (Pack of 1), Style: SPF 50+

The best sunscreen I've ever used. I burn super easy, just 30 min outside without protection and I'll be a lobster the next day. I can apply this once in the morning and be protected all day. Pros: - Doesn't wear off quickly - Haven't had a single sunburn since I started using it - Doesn't have a strong chemical smell - A little goes a long way - Resists sweat well Cons: - Has a white cast so you really have to rub it in - It doesn't sit light, you can definitely feel it on your skin I would recommend this to anyone and everyone looking for sunscreen.

Perfect for Dominican Republic sun rays! No sunburn for my fair skin, still allowed slight color.

Love this sunscreen!!

Size: 5 Ounce (Pack of 1), Style: SPF 50+

This is my favorite mineral sunscreen. It goes on white, but the white cast leaves very quickly. The SPF 50 keeps me adequately covered in the Arizona sun and I've never gotten a sunburn when I have it on. It's a must have if you enjoy the outdoors in the summer.
