Restores the appearance of healthy nails. Sanitizes and dehydrates eliminating the environment necessary for the growth of mold and bacteria. Yellow, brown or green discoloration at the nail tips and spreading down towards the cuticle are a hallmark of this condition. Thymol in alcohol is a time honored formulation used by dermatologist to treat these types of nail infections. Amoresse Thymol is not used to treat true nail fungus. Treatment is successful when the changing nail color no longer continues to extend toward the cuticle. Old infected nail must grow out and this may take 6-12 months. Continue treatment with Thymol throughout this time. Apply one to two droplets twice a day under nail plate. Minimize water contact with nails. Discontinue use of artificial nail tips if wearing them. Signs of inflammation, pain, lumpiness, black color change, or pus coming from the cuticles are all reasons to see your physician.
