I have only used this kit 1 time, and I can already say that I love it. I love the easiness of the application, how fast the process goes, how pretty my nails look, and how long it lasts. No nail product stays on my nails more than 1 day without chipping, even nail salon manicures. Granted, I have never tried gel polishes. I do a lot of house chores, gardening and cooking that chip all my manicures. I have had this Conceal and Go Duo on my nails for 1 week already and it is just starting to show signs of wear. Next time I use this Duo I want to try reapplying the top coat every other day to see if it will make it last longer. I haven’t done that this first time. You don’t need to use a base coat with this product. The company actually doesn’t suggest the use of a base coat so you can enjoy the full benefits of the Illuminating Concealer. How easy is that! But you certainly can use a base coat to make your manicure last longer.
