Perfect Everyday Tinted Face Sunscreen
I am a long-time user of Think body sunscreen and tried this to replace my current department store tinted face sunscreen, which is being discontinued. I was amazed how well this performed, given the low price! It is literally 1/4 of the cost of my current face sunscreen and I am almost as happy with it! It was much lighter in tint than I was expecting, but blended easily and provided more "cosmetic" coverage than my current tinted face sunscreen, but without looking making me look made-up. My skin is light with reddish undertones, and it really helped to tone the red down as well, an unexpected bonus. That said, I typically use make up that is either the 2nd (or occasionally 3rd) from the fairest shade in the line, regardless of brand, and I am not sure how well this product would work on someone whose skin is even a little darker than mine, without being obvious. It is definitely too light for my sons, who have more olive-toned complexions. This product is highly moisturizing, and does take about 10 minutes to "set" before I feel comfortable applying powder to cover up the shine it leaves (a little more than a "glow"). Its efficacy is excellent--I really put it to the test outdoors and was pleased to see I had not to picked up any color from the sun when I washed it off. The other big plus is that it did not make me break out, and I have what my dermatologist calls, "reactive skin," which means anything from chemicals in face products to the hairdryer at the salon have been known to set it off. Finally, like their body sunscreen this face sunscreen gets a safety rating of "1" from the Environmental Working Group. I think I have found a winner!

Nice face sunscreen!
Great face sunscreen! It has high zinc and looks nice under makeup. I will continue to purchase. Not sure why it’s only a SPF of 30. It has 24% zinc which is higher. It’s a little thicker than some of the thinner ones I’ve used but I like that. I feel I’m getting good coverage

An Effective Sunscreen With Some Drawbacks
I like the safety and effectiveness of Thinksport tinted sunscreen. It's formulated carefully and I found it quite effective; I appreciate that it's not tested on animals. It is easy to apply and blends in with no chalky or white residue and doesn't come off easily (in fact washing it off later is not especially easy). I very much appreciated its effectiveness as I didn't ever burn when using this tube.
With all that in mind why did I give it only three stars and throw away the tube before I even used half of it? Two reasons: I frequently run while wearing sunscreen and that, obviously, leads to sweating. When you sweat with this anything that you touch with a treated surface will be smeared with the brown tint of the sunscreen (particularly your shirt when your face, neck, or arms contact it, which may be more than you think). This looks akin to pancake makeup on clothes. It washed out of the shirts I got it on, but they did seem to get dingier after multiple cycles (especially around the collar). The second reason I didn't like this sunscreen is that when applied to the forehead and then perspiring this product really stung my eyes. I have had that product with some other brands as well, so it's definitely not a Thinksport exclusive issue, but still it's annoying.
I used almost half the tube then switched back to my normal brand, which while also not ideal in some ways, doesn't have these issues. I have not given up on the Thinksport brand entirely, as I have recently purchased some of their untinted sunscreen. I have only used it a few times, but initial impressions are good.
If you are unconcerned about the issues of staining from this product or you don't plan to wear it while doing anything strenuous, the tinted Thinksport sunscreen product may work great for you: it's easy to apply and quite effective.
