Mexico - reef safe suncream

[1lov3comps]

We're going to Mexico during the summer and will be visiting some centres and have read that you must have reef safe suncream. I've found a few online that claim to be but most don't have anything written on the bottle so I'm not sure if they'll be accepted.
Has anyone been and if so, what suncream did you bring?

maybe see if there any supermarkets near the resort ,any close by would bound to have some.When i went to florida i found the best suncream by going to a local wallmart

That was my thought but DH isn't keen - I'd be more laid back but he'd be stressing in case we couldn't find any and it stopped us going on the day trip. Figured it'd be easy to just buy some on Amazon or whatever but according to articles I've read, it needs to say both 'reef safe' and 'waterproof / water resistant' on the bottle and that's where I'm struggling with it

Ultrasun says it is both.

All Nivea suncream is reef safe. I bought mega-expensive stuff for my first trip to Mexico before I found out about Nivea!
