Safe Sea SPF50+ Kids sunscreen - Jellyfish and Sea lice protective lotion. Very Water Resistant, Sensitive skin Reef-Safe Sunscreen. Oxybenzone and Octinoxate free, Paraben free, 4 fl. Oz. Pack of 2

I have been using this sunscreen on my sun for a few years. I don’t know how it works but since he’s been using it, he has not had an issue with jellyfish stings or sea lice. We travel and go boating a lot. I will say, he hasn’t gotten bit on his extremities by sea lice (where I put the sunscreen) but he has gotten bit under his rash guard and shorts (no sunscreen). So it has worked well for us. I don’t use this sunscreen on his face, not because he’s ever had a reaction but just because I worry about chemicals. He’s also never gotten a sunburn with this sunscreen.

It works! But re-apply a few times throughout the day depending on how much you’re in the water.

I can't say if this kept us from getting stung my sea lice or other jelly fish. I can only say that during our hour of snorkeling in the Caribbean, we didn't get stung once. I can say that as a sun block, this worked very well. Neither of us got the least sunburned. The only down side is that this goes on very white and it's a bit hard to smooth in. It doesn't seem to affect its effectiveness at all, but it does look rather messy. Still, it does work, and that is what we considered important. If it had worked as well but had not been so messy looking, I would have rated it 5 stars.

This product smells horrible. I bought this for face sunscreen, but it's hard to even put on. It stinks horribly. It works fine, but with the stench, I just can't use it.

It's very thick, but I think that's a good thing--it just takes some time to get it all rubbed into your skin. A darker-skinned person (like my husband) might look a little like they're in white face until it is good and blended. At the end of an 8-day Caribbean cruise, we still had plenty left, even though I was putting it on constantly throughout the day. We did not encounter any jellyfish, so I don't know whether or not it works, but because it's so thick, I think it probably will -- especially with the little bitey shrimpey things that come out at night and make surfacing after a night dive really painful.

I spend my winter in Florida but since last year I have started getting a terrible reaction to jellyfish. I was so disappointed about not being able to go into the ocean again. This product has definitely helped. It’s a very heavy sunscreen that I put all over my torso under the bathing suit and it seems to work.

Worked wonderfully for me on a 5-day cruise to the Bahamas. I'm a ginger and burn very easily, I also have sensitive skin and always manage to attract something to sting or irritate my skin in the ocean. I kept this stuff coated on me during beach time and during extensive scuba diving and boat time and managed to survive the trip without any burns or stings!

First trip to Fiji resulted in multiple sea lice stings. Took this with me on the next few trips and no stings! If you’ve ever experienced sea lice stings, you know how bad they are. I swear by this lotion and take it on every snorkel / scuba vacation!
