Gel Nail Polish, in fact, is a photo-curing Product just like Uv Gel Nails and for this reason it “dries”or solidifies or catalyses Exclusively through the Exposure to UV Rays of Professional Nail Lamps.
Pay Attention because Uv Rays are also present in the Sun, therefore avoid to expose Nail Products to the direct Sunlight, avoiding their Involuntary Catalysis!
