Would this sunscreen interfere with my pre/probiotic microbiome friendly skin care? Would love to find something with pre and probiotics.

I have no idea, that would be a question for your Dr.

The product details says it's 4.5 oz, the picture says 3.3 oz (100 ml volume), and on 11/5/15 gin said 3 oz. what is the true weight of the contents?

Mine says 3.0 fl.oz. on the label, but my bottle looms different than the one here, totally different packaging, so the volume is probably different as well.

Is the corn starch from a non-GMO source of corn?

Not sure... front of bottle says ...yes non GMO ingredients I think this sunscreen is as good as it gets... I’m open if there is a more natural sunscreen that is water resistant and reef safe (per the company). I bought mine for a trip to an area with natural reefs... and wanted healthy ingredients for our skin.

does it have an expiration date?

Yes, it does have an expiration date!
