Works
Color: Mayday
A little does go a long way. It’s on the pricy side but it was worth it. It’s not something to be using all the time. But definitely a back up for whenever you do get sunburn

Really effective!
Color: Mayday
I was totally blown away by how effective this was on my recent burn, I wish I had taken pictures. So much so that I did a deep dive into the ingredients and formula (I'm a nerd). My takeaway is that this is a bargain for the quality of ingredients and the care of the formula. The product absorbs quickly, is non-greasy, and relatively moisturizing and most of all, really effective. I personally appreciate the lack of any real scent or fragrance. I'm a big fan!

Not the results I expected
Color: Mayday
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.
