Comet Relief is a metallic gold shimmer from ORLY, which makes use of Advanced Oxygen Technology. Oxygen and water can penetrate the nail allowing it to stay moisturised. No basecoat or topcoat is needed with any ORLY Breathable Treatment + Color product and with ingredients like Argan Oil, Pro-Vitamin B5 and Vitamin C your nails will stay well moisturised. ORLY's permeable formula means better adhesion, less chipping and longer lasting colour. Apply two coats of ORLY Breathable Treatment + Color to the nail.
