Kerassentials Client Reviews 2026 The most prominent active component in Kerassentials is Undecylenic Acid at a 5% concentration, a clinically recognized and FDA-approved antifungal agent derived from castor oil that works by inhibiting the growth and reproduction of fungal cells. This is complemented by the inclusion of Tea Tree Oil, perhaps the most famous natural antifungal in the world, which provides powerful antiseptic qualities to the Kerassentials blend, ensuring that the surface of the nail and skin remains sterile. These active fighters are balanced by a suite of moisturizing and protective ingredients such as Flaxseed Oil and Almond Oil, which provide the essential vitamins and omega-3 fatty acids necessary to repair brittle nails and prevent the cracking that allows fungus to enter the skin.
