KeryFlex is a cosmetic solution for unsightly toenails. It is immediate and provides a significant change in appearance in only a matter of minutes. The KeryFlex toenail is light, flexible and natural.Flexibility is important compared to rigid acrylic toenails which don’t bend with the natural movement of toes and feet and lead to further toenail trauma. It is also safe to use on human skin and doesn’t cause irritation or further damage to your nail or skin, allowing your toenail underneath to grow naturally.It is also non-porous and will not allow moisture to penetrate between your natural nail and prosthetic nail. This helps prevent a moist environment which can further exacerbate any existing fungal toenail infections. KeryFlex can also be used during most antifungal treatments providing a cosmetically pleasing appearance.
