Hi, dip powder and POLYGEL are 2 different products. Gelish Dip is a soak off 2 week color or French system great for adding more rigid strength. You can also apply over short to medium length tips for " party nails". It's best to file off 80% of product before wrapping for soak off removal. It dissolves in 10 min and leaves nail clean. I use it for clients who aren't getting best results with gel polish. It does not need a lamp. Just be careful of proper cleaning of brushes and caps to keep bottles from sticking or clumping.
