This product has litteraly changed my life. Because I love dark polishes I often have discolored nails (yes, I do wear base!), and it's always been difficult to find the perfect pale "neutral" that'll cover the yellow on the nail plate but not look ugly against my pale skin. Now I just put on a single coat of Mava-White, and my nails look perfect. No yellow, no streaks, just clean, healthy looking nails.
