PUREFIX Deep Renewal Antifungal Treatment PenClear, healthy nails without the mess, smell, or embarrassment. Id given up hope after trying every cream under the sun vinegar, pharmacy sprays, all of it. Nothing lasted. PUREFIX was the first thing that actually worked. Its clean, easy, and you just brush it on like nail polish. After a few weeks, I saw new, clear nail coming in. My husband used it too and his cleared up as well. I actually wore sandals on holiday for the first time in years.
