To use this Gelish Prohesion Nail Sculpting Powder, first, make sure your nails are clean and dry. Apply a base coat to your nails. Then, dip your nails into the powder, gently tapping off the excess. You can repeat this process to build up the desired thickness. After that, apply a top coat for a shiny finish. When using, avoid getting the powder in your eyes or mouth. Store the powder in a cool, dry place away from direct sunlight. To maintain the look of your nails, avoid excessive contact with water and harsh chemicals. If the nails start to chip, you can do a touch - up by applying more powder and top coat.
