Rated 5 out of 5 by from Thinksport has saved my skin! I started using Thinksport almost a year ago when I began training for triathlons. The change in my skin has been amazing. I have swum outside for years and have unfortunately developed sunspots. After learning about thinksport and consistently using it for every open water swim, ride and run in the oppressive Texas sunshine, I have seen a huge decrease in the wear and tear on my skin. I have a lot fewer sunspots and I have never once burned while using Thinksport. Thinksport has the perfect consistency and will not run in your eyes while sweating or swimming. I highly recommend Thinksport and I refuse to ever use another brand again!

Rated 5 out of 5 by from Best Sunscreen I've Ever Used I've always had trouble finding sunscreen that didn't feel gross and/or make my sensitive skin break out. A friend gave me thinksport's sunscreen and I'm so glad I tried it. The first time I used it I was out in the sun all day- swimming in the ocean, slacklining, practicing acroyoga with friends. This stuff provided great sun protection, even with all of the swimming and sweating that I did, and I didn't burn at all. Based on my experiences with almost every other sunscreen I've tried, I expected my skin to break out over the next day or two, but it didn't. Quite frankly, I was pretty amazed. It doesn't feel greasy or sticky, is super water/sweat-resistant, and it smells delicious. Added plus- it doesn't irritate sensitive skin!

Rated 5 out of 5 by from Best Sunscreen Around Absolutely love Thinksport products. I have worn the Thinksport sunscreen in the hot/humid conditions at Ironman Hawaii (9 hour race) the the past couple of years with no signs of sun burn. Not only does it protect me from the dangerous UV rays but it's also nice to know that it's good for my skin with no harmful chemicals added. Plus, I really like that all of the body products and sunscreens smell great

Rated 5 out of 5 by from BEST SAFE SUNSCREEN OUT THERE As a trailrunner and triathlete, I'm out in the sun A LOT so using a sunscreen that protects me WELL in a HEALTHY way is very important to me. Thinksport's use of 20% zinc oxide makes for a clean sunscreen that goes a long way, with no overspray or waste that you get with aerosol-type sunscreens. Tube size is GREAT and perfect for travel, in my gym bag, in my crew bag, and at home. If you haven't tried it, you won't be disappointed!!!

Rated 5 out of 5 by from Skin Saver! The small scar on my nose as a reminder of a small skin cancer is my best reminder to seriously protect my skin. I bought the Think Sport after careful research and tried it out on a 16 day camping trip in St. John. Despite snorkeling, hiking and swimming I had absolutely no sunburn. I will say that I also wore a hat and long sleeved rash guard when I could, but I still got plenty of exposure. ThIs product isn't greasy and rubs in, yet water beads up in your skin and gives you great protection even during water sports and when sweating. Worth every penny!

Rated 5 out of 5 by from Clean scent, durable protection Thinksport's sunscreen smells great and it doesn't make my skin feel greasy. Many sunscreens burn my eyes when I start to sweat but this one stays put. I am an active runner, hiker and surfer, and love being outdoors. I don't want to have to worry about reapplying sunscreen every hour or what kind if chemicals I am putting on my skin. I will definitely continue using this product in the future.

Rated 5 out of 5 by from Excellent sunscreen for pool & open water swimming I train and compete in open water swims. I was surprised how water resistant and effective Thinksport sunscreen has been for me. I am completely sold on using exclusively when I am in the sun and water.

Rated 3 out of 5 by from Good protection but with drawbacks I like the fact that the main ingredient is chemically non reactive. I went to New Zealand and it did provide excellent sun protection. But I found it to be extremely oily. After applying I could not use my phone because everything you touch gets the zinc on it. Its difficult to remove and it did damage some of my cloth and car seats. You have to be very careful with it and make sure it doesn't come in contact with anything else but your skin. In my opinion the drawbacks more than outweihj the benefits so I will not use it again.

Is this the bright white variety or the clear-ish variety of zinc oxide sunscreen?

Is this biodegradable? 

Asked by: emiliecycle
We have attempted to contact the manufacturer several times regarding the Thinksport Sunscreen SPF 50 and have been unable to get a response. Thinksport does however give a complete ingredients listing on their site.
