Usage with Gel Nail Polish Apply two thin layers of gel polish and cure per the gel’s instructions in between layers. Black works best but you can use any color. Apply a thin layer of any gel top coat, cure per gel instructions but don’t over cure. Put a small amount of powder on the nail and buff with your fingertip, silicone tool, eye shadow applicator or brush. Continue gently buffing until the mirror effect is achieved over the entire nail. Wipe excess powder with a dry brush or a clean finger. Apply a thin layer of gel top coat once more, make sure to seal free edge and sides to prevent from peeling and cure per the gel’s instructions. Usage with Regular Nail Polish (last 1-2 days) Apply two thin coats of regular nail polish, let dry between coats. Black polish works the best but you can use any color. (Optional step) Apply a top coat to smooth the nail surface. Let it dry to the touch but leave a little soft where it can still be dented. Put a small amount of powder on the tip of your finger and gently buff it into your nail. Continue gently buffing until the mirror effect is achieved over the entire nail. Wipe excess powder with a dry brush or a clean finger. Apply a transparent peel off base coat, let it dry and then apply a regular top coat. You can also just use a layer of water based top coat over powder.
