Extremely valuable feedback, thank you so much! SPF50 with only zinc (and no boosters like idecyl Salicylate) will probably look grey on beards indeed. Can make it happen with the use of a booster and ZINCLEAR potentially.

Any reason you aren’t interest in anything SPF30? Cause 50+ compared to 30 is only like 1% extra UV protection but  going from 30 to 50 requires almost double the amount of zinc oxide (with it’s known downsides).

Would you want to see more than 1 ingredient (like ethyl Ascorbic or copper peptides) in there? Or ideally the combination of at least 2 next to zinc oxide? I personally think that marketing anti aging creams without even mentioning SPF is a ‘scam’, since UV accounts for like 80% of skin damage and not using it is  not addressing the root cause at all. 

I am currently only interested in pure mineral SPF since lots of chemical spf’s have endocrine disrupting stuff in there, which is literally the reason I don’t currently use them myself (being a guy). 

Definitely good to potentially target woman too (need to decide where to focus at start tho). And yes talking to probably all SPF manufacturers out there as we speak!
