What is the difference between Glossy Non-Transfer Top Coat and Liquid Lip Gloss Coating (Shine Filler)? And if we want to make a lipstick that can protect the sun as well. We can mix sunscreen at Coating or must mix sunscreen at the texture of the lip color only. And do you have any recommendations for the sunscreens used in lip balms? How many % should I put sunscreen to be harmless?
