I picked up my first Clinique foundation when I was 16 (probably a little young to start with) but this probably contributed to the reason why I still love and use it. At that time, I was using the Superfit range, which has now been discontinued.
I loved this because it was so light and blendable. Even a makeup rookie (like me at that time) could apply it perfectly. Yet while being light, it still gave me sufficient coverage that concealer could be easily skipped. And best of all, the result was a dewy, youthful finish.
