What it does: Sephora by OPI Nail Colour Remover is a fast, gentle nail polish remover without harsh, drying effects or the tell-tale white residue left behind by traditional acetone nail polish removers. The superior formula contains grape seed oil, vitamin E, and extracts of sea kelp and aloe vera, making it more effective than traditional formulas.
