So what are primers, really?
The make up trainer last workshop told us, that same with painting the walls, the face also needs primer. Basically it evens out the skin for smooth application of foundation. She also said that BB creams will do if we don't have primers. I've been using Maybelline's BB cream since last year (but not regularly) so I figured out it might be a good way to go since I do not have any primers.
