Do you use primer regularly?
My answer: eyeshadow primer, yes. My lids are oily and without it, my makeup would melt within a couple of hours. My favourite is Too Faced Shadow Insurance, because of how lightweight it is. Instead, I wear a face primer only on special occasions or when I know I’ll stay out of the house for the whole day (and evening too) to make sure my makeup will stay put, and save me from retouching it every few hours or so.
