Orivelle Fungal infections of the nails, known medically as onychomycosis, are among the most common and stubborn nail conditions affecting people of all ages. They cause discoloration, thickening, brittleness, and sometimes even pain or an unpleasant odor. Treating such infections has traditionally been a long and difficult process, often involving oral medications that can cause side effects, or topical creams that fail to penetrate the dense nail surface effectively. orivellepen.org.uk/
