Agree, 102 is better than 103, unless your skin is a bit dark.
From my experience, RMK is among the best 1-2 foundation. I would evenbe better if you use it together with its "make-up base".
I also use RMK 102 liquid foundation... i think RMK liquid foundation is the best... better than Giorgio Armani, IPSA, Shiseido, Lancome, KP, CP... even GA is expensive, but RMK is better!
