I already will have to sunblock her face!
I know you didn't ask, but... Harley has a pink nose, so I've tried several sunblocks! I even bought a full-face Cashel fly mask with the nose piece, which he promptly removed. Three times in a row.
I dislike the creams and pastes. They attract dirt, get rubbed off everywhere, and generally make a big mess.
I bought this powder a couple of years ago: https://www.mypetsunblock.com/produc...international/
It worked well, but with the currency exchange and shipping, it cost me a small fortune. The main ingredient is powdered zinc oxide of course. So I just ordered a big bag of cosmetic-grade fine powdered zinc oxide and it works great! It does really stick to the skin (I have to scrub it off my fingers) and he has never burned with it.
