I think my face can come across as too ';contoured'; and i'd like to fill it out using makeup...how do I do that?How can I use makeup to make a thin, square face rounder and fuller?
Try using a bronzing lotion on your face, a tanned face will always make it look fuller yet still attractive, also, blush on your uppercheek bones sweeping upwards toward your hairline will fill out your cheeks a bit. =)
