I really find that the YSL formula has improved since a few years back, don't you think so?
I don't know - these are my first YSLs. The formula really is superb. one medium coat for full opacity or two thin coats (which is what I did on the first two, since I didn't know for sure) The Bronze was just one medium coat.
They do need a top coat though as they dry kind of dull. The top coat bring them to life.
