Is it tinted? some answers say yes, others no...??? White cast?

The body sunscreens are not tinted, they are white in color. In regards to the product leaving a white cast, it really depends on your application. If you dot the product all over the area and rub it in, the white disappears within a minute vs if you apply a large amount in one spot and try to spread it to an entire area. There is a video of a dermatologist explaining how much and how best to apply mineral sunscreen and avoid the white cast that can be found on the manufacturers website (found by clicking at the bottom of the home page under customer care - videos).

is this sunscreen waterproof?

It is a very thick sunscreen and has worked perfectly for me, but even if a sunscreen claims to be waterproof i always rub more onto my skin after getting in the water and drying up, especially if it is between 10 am and 3 pm

Is this non comedogenic?

The term non-comedogenic is more of a marketing term and there’s really no standard in place for regulating that term. We did a 50 person RIPT test without any skin reactions reported. That being said, every person's skin is different and we always recommend doing a patch test of the product to see how it works for you. If you have an issue, we will work with you.
