I used a green tinted foundation when I was a teenager (and that wasn't yesterday! LOL) because my cheeks were very ruddy and I was self conscious about it. It was from a range by Boots, a large UK chemist chain and called Boots No. 17 Color Corrective Fluid.
This stuff really did work and you only needed a tiny little bit of it. You applied to the skin and then put your normal foundation over it. Easy peasy and made me feel a lot better about myself back then. I know it sounds weird with it being green but once I tried it I was hooked and used it for years.
I don't know if they still make it though. Their website is http://boots.com if anyone wants to find out. You could always contact their customer service and ask if it's still available or if they have a similar product line. That was thirty years ago after all! Man, I'm getting old.
Hope that helps!
