This powder adds a special effect to change any colour to a mirror finish. When used over black it gives a mirror silver and over a pink it is more rose gold mirror. To achieve the mirror effect you need to put Lac It! No Wipe Top Gloss under the powder. You apply the No Wipe, which is dispersion free, and cure it for only 10 sec in UV or 5 sec. in the En Vogue Infusion UV/LED Light.
