Formula X CLIX! are convenient quads that hold four mini nail polish, serum, or cuticle oil (depending on the set), meant to restore your nails of most common nail issues. Each bottle is 0.1 oz (super tiny) and a great for travel. The sheer color and top coat have earned a permanent spot in my toiletry bag. I love these little sets! The Formula X CLIX! Brightening Prescription is meant to remove stains and offset discoloration. 

Step 1 - The brightening treatment serum is applied first and dissolves quickly. 

Step 2 - The color correcting base coat has a light purple hue that combats yellow stains. This color corrector is not as thick as polish and can probably be used alone for a quick color-pick-me-up.

Step 3 - The sheer color is the perfect pale pink (my favorite).

Step 4 - Although it is clear, the color plus top coat kinda looks holographic and has a slight hint of blue color.

Only four coats and you have brighter nails. The color is pretty, but a little too blueish for me. It could be that I don't have nail discoloration, so there is no color to neutralize and the blue stands out more. Of course, I purchased this set cause it's mini! I also purchased The Strengthening Prescription, The Hydrating Prescription and The System To Go - I will post reviews soon.
