Gelish PolyGel Slip Solution is one of the safest liquids in the nail industry for creating beautifully shaped nails in no time. It eliminates friction so there's no drag when you're brushing and shaping the nail. It doesn't activate curing so the nail will not dry too fast. It lets you gently glide the PolyGel into place and prepare the nail so it looks as natural and realistic as possible before it dries. No hard scent, no unpleasant scent.
