Formula X Alchemy II is a predominantly copper polish with specks of blue, pink, and gold.
This is 2 coats plus top coat. Formula was pretty good, it did try pulling away from my tips a bit.
You can see how the base of Alchemy II is a rich coppery color while Alchemy is a more silvery base color.
Alchemy (on the right) has similar specks of blue and pink, but the formula on it was much thinner than Alchemy II – plus you can see how much it pulled away from my tips.
I was lucky enough to pick up the original Alchemy on clearance but I just loved Alchemy II so much to pick it up full price at Sephora. This is limited edition, so grab it while you can!
