I had quite a bad accident some years ago when I smashed up my nose so badly I had to have splints inside?. Unfortunately, since I was wearing glasses with a metal piece across the bridge of my nose, it also cut in quite badly and has left a scar (which I'm sure I'm much more conscious of than anyone else). I don't wear much makeup - mostly mascara - but I wanted something to camouflage the scar, so I plucked up courage and asked one of these cosmetic ladies for help - and she couldn't have been nicer. She spent ages deciding on the right tone, didn't push anything else, and made me feel so much better.
My DDiL works for Avida (which I admit is pretty expensive) but I do know that she would be delighted to help someone who really wanted help and advice - much more than the unpleasantly rude rich women she often has to deal with. So I suggest you go somewhere, be honest and tell them what you want, and enjoy the experience.
