This is my favorite sunscreen product. This is for serious sun protection because it actually works. We use it in the Caribbean and Mexico and it is the only sunscreen that has succeeded in keeping us from getting burned when we spend all day on the beach. It does not have any white cast either and I believe the ingredients are safe for reefs. I have purchased my second bottle, and I won't be buying any other sunscreen. I haven't been able to locate it in stores so I purchase on the internet.

This is the most amazing, underrated, sunscreen brand on the market. Performs 100 times better than all other sunscreens chemical or physical. My review for this is similar to the one I gave for Mexitan SPF 50 except that I prefer this one more.
Like the SPF 50, it sometimes comes out clumpy yet glides on your skin once your spread it. It goes on smooth like a moisturizer but dries immediately and is not sticky or greasy at all. It contains 6% zinc and 6% titanium with green tea. Although it has less zinc than the SPF 50, I like the 30 better because it does not leave a noticeable white caste even if I overapply. This is perfect if you have darker skin and want a physical, all natural, biodegradable sunscreen. Also because of less zinc, it's a tad more liquidy than the SPF 50. I don't like those sunscreens that are so thick that you have to rub into your skin like crazy. That's not cool to do to your face especially around your eyes. This protects extremely well even with the lower zinc oxide. Besides, you are supposed to reapply every 2 hrs (40 mins after being in the water) to maintain the protection whether it's SPF 50 or not. I highly recommend Mexitan sunscreen to everyone.
UPDATE: This has not worked out too well for my face because my skin is really oily and this just made it feel really icky. But for body, Mexitan is fantastic! I have remained pale under the blazing sun. If you have normal to dry skin, I think it would be ok.
UPDATE # 2: Still love this and the new formula is even better! Got another bottle under the name TROPICAL SANDS which is the same as Mexitan and they left out vitamin A over concerns that it may increase your risk of cancer. The new formula is not clumpy like the old and comes out very smooth like a lotion. Makes it easier to apply and everything is mixed in really well. I tried it on my face too and I love it!!! I couldn't use the old one on my face b/c it made me greasy but this one gave a non-sticky matte finish. Mineral makeup went on really well after this. Again, never tanned or burned with this sunscreen on and I only apply ONCE for the day.
