A must have for your summer bag
I am 100% devoted to Blue Lizard products! I got some extra sun and needed relief, fast. This non-greasy nor slimy cream is exactly what I didn’t know I was looking for. I had applied aloe alone to my skin and received no relief. Within minutes if not seconds of applying this, I had noticed improvement. The consistency is not too thick or too thin, it absorbs into the skin nicely and can be reapplied without getting cakey. It gave my sunburn relief while also moisturizing the skin. I haven’t peeled at ALL. I love that it has clean ingredients and a neutral fragrance. My skin is so sensitive, so having natural ingredients is a plus. Blue Lizard After Sun is now my holy grail and I will recommend it over and over.

HANDS. DOWN. AMAZING.
I have used other products for after sunning in the past. This stuff is AMAZING and I wish I could be a spokesperson for it. I am extremely fair skinned and used this on my vacation at the beach. I used some spf which always leaves me slightly red. I put this on every night and the redness was gone by morning! I was ready to hit the sun again! It doesn’t have a scent and doesn’t leave a sticky lingering feeling or weird smell either. Just moisturizing and safe for my acne prone skin. I will buy this and use this forever!!!!

Phenomenal.
Got a baaaaad sunburn from head to toe. On day 2 or 3, I finally got this stuff. It took the sting away quickly. No smell, and it feels nice on the skin. It’s thin and spreads well. Definitely helped keep my burns moisturized - I didn’t even peel, save for the blisters on my shoulders. My boy even let me put it on his pink little cheek, and

Miracle in a bottle!
This was a lifesaver, I got badly burnt just walking for several miles one day. It was only in the 80's, not 100 degree's but still hot. Where I live there is a poor air quality, too. I was red as a lobster! It was painful and then i saw this. Read the reviews and hoped it would help. Did it ever! It not only helped sooth my skin, calm it down, it dramatically reduced the redness in just a few days! I should have saved the photo's of the before a several days after, but I deleted them. (I wasn't thinking and they were kind of gross). They would have shown the extent of the healing thanks to this cream. I even had some blisters, that shrank in two days after applying this! By the fourth day of applying this cream, they were gone and my skin went from being deep red to pink. What is even more awesome is this moisturized my skin! I have sensitive skin and this did not irritate it. So that was a plus! My only issue was it's a little tacky, sticky after you apply it. So don't apply right before bed, unless you want to be stuck to your sheets. If you're in dire need of relief and to reduce the redness, this is what you want, it is a miracle in a bottle!

Good sunscreen
I originally had purchased the spray version of this product. Unfortunately, the cans clogged so I needed to return them and I ordered this instead. It tends to go on thick but I really need heavy protection so it’s fine. Seems to give good protection and I will buy it again. I’m only giving up four stars because I would’ve preferred the spray.
