Get it
Size: 8 Ounce (Pack of 1), Style: Cool Down Lotion
Love this stuff. Best recovery from the sun I have found. I am very fair and even with sunscreen sometimes still get a little burnt. My friends who get tan and had a long day in the sun are quick to grab this from me and use it at the end of the day. I highly recommend this for anyone. It’s cooling and hydrating. Repair or maintenance for your skin, it’s great for both options. Lightweight and easy to apply. Hands down, worth it!

Smells Great and Works Well
Size: 3 Ounce (Pack of 1), Style: Cool Down Lotion
Smells great and goes on really smoothly. Skin felt soft and refreshed after use. It is pretty "liquidy" and can come out of the bottle a little on the quick and messy side, but nothing too terrible.

Works VERY well, NOT sticky, smells AMAZING!
Size: 16 Ounce (Pack of 1), Style: Cool Down Lotion
So... I had sunburn... very painful across my whole back, top of my forehead & the back of my arms. Stupid, I know... USE SUNBLOCK PEOPLE! However, if u don't because u want "a little color" and end up like me, then I highly recommend this after-sun product. It smells amazing and doesn't leave the sticky residue like green Aloe Vera. After rubbing it in, my hands feel super soft. It gives my skin the hydration it needs so I won't peel (and lose the tan I was desperate for). My personal hack... After the sensitivity of the burn calms, I like keeping a bottle in the fridge for that extra cooling sensation. I love this stuff! Sun Bum is a great product... u should definitely try the sunblock tho, it worked where I applied it! I didn't take a pic for obvious reasons, but when u rub it in, it will dry clear.

Works Exceptionally well without feeling like you just applied Super Glue to your Body.
Size: 8 Ounce (Pack of 1), Style: Cool Down Lotion
I would provide a picture of the bottle but TSA took mine. This is some of the best post sunburn lotion I have ever used. I just finished writing a review of a sunblock lotion that did a great job, what I did not mention was the only sunburn I got was on my lower back where I didn't apply that lotion. It was a pretty uncomfortable burn, especially when I tried to sleep in the forward berth of a sailboat, or when I tried to wear swimming trunks with an elastic type waist, thankfully I had a couple of sets of board shorts that alleviated that irritation. But back on point. What I like the most about this lotion is how it applies. Usually, in the past, I did not like using aloe lotions because I felt like it was like glue when it dried on my skin and I felt like it made my skin feel tight. This stuff applies extremely well and I'm not exaggerating one bit when I say the relief is IMMEDIATE. As soon as I applied it to my sunburn, I felt immediate relief! It also doesn't feel like you just spread a bunch of super glue on your burn when it dries. It absorbs into your skin, cools your "hot spot" and doesn't leave a residue to get onto your clothing, or onto the mattress in my berth on the sailboat. Win and win. I can't recommend this product enough. The only negative experience was when TSA snagged my bottle going through security in Miami because I forgot to put it in my checked bag. But that was just the good ol' TSA doing their job in the amazing way they always do. (sarcasm dripping sounds) It works so well that I bought a replacement. So I would recommend purchasing the 3 oz tube if you plan on traveling with it. This is an excellent product, I'm not sure how long it lasts, because I forgot my sunburn was nothing me, or it enabled me to fall back asleep after applying. It does have that coconutty smell, but it's not like I just spent 3 hours in a hot tub filled with coconut oil. Hmmm... Idea forming... Anyway, purchase with confidence, this Texan who got a sunburn on his lower back and treated it with Sun Bum approves this message.
