I have this too, it is the BESTEST stuff. Agree!

My husband and I went to Hawaii last May, and also needed some reef safe sunscreen. Unfortunately, we were told by the local shops that they only sell the reef safe sunscreen, so buying any that were in the shops were okay. We later found that this information was false. We found out that the best bet is to order a certified reef safe sunscreen from a reputable company online before you go. This does require you to get a smaller bottle, or pack it in a suitcase that you check through for airport screenings.
