Actually does what it says!!!
Color: Mayday
Terns is AMAZING!! I wish I would have found it the day after my burn. I feel asleep on my hammock for 3 hrs and my face turn into a tomato 🍅. Next 3 days just tightness and sore. Then comes the peeling and it was like face dandruff. I search online did my research then found on Amazon and checked out the reviews and pulled the trigger. I have never been happier with a product and it actually does what it says it will and the reviews say. I washed my face first then put it on and it was like ahhhhh. The first 2 days I had to put it on twice a day but my face never once looked like I had put Elmers glue on just to peel off. Then everyday after, just 1 application needed but 2 if you want because my skin was glowing!! I think I might just make this my new face moisturizer. Do yourselves a favor and stop looking just go with this one!

Actually works!
Color: Mayday
The bottle is small but it does a big job with a small pea-sized amount! Takes the burn out and reduces redness and peeling quickly! Love this product!

Save your money
Color: Mayday
We bought this specifically for our trip to Florida and had high hopes based on all the positive reviews. Unfortunately, it was a complete disappointment. I used it on all five members of our family exactly as directed, and it did absolutely nothing for any of us.
Not only was it ineffective, but it was also extremely overpriced for the results we got—which were none. We felt like we wasted our money on a product that simply doesn’t work as advertised. Looking back, I wish I hadn’t trusted the reviews and had saved my money instead.
I rarely leave negative reviews, but I feel it’s important to share my experience so others can make a more informed decision. Based on our experience, I would not recommend this product.

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!
