Apply a color gel of your choice as usual and cure it.
Do not remove the sweat layer.
Now apply a very thin layer of color gel in a contrasting color and DO NOT harden it!
Using a fine brush, apply the Booster Effect Gel selectively or in fine lines to the still wet color gel.
Now the effect gel begins to influence the wet color gel by creating a batik-like effect.

Once the desired effect is achieved, please cure.

Then apply a finishing gel and let it harden. Done.
Each nail is unique. Compatible with all color gels.
