The article highlights the Dermavia+ Fungal Nail Treatment Pen, sold on Amazon for £22.99, as a treatment for yellow, brittle or discoloured nails. The product uses essential oils and biotin and has a 4.5-star rating from more than 1,000 reviews. Customers praise its brush-tip application and report clearer, healthier-looking nails, although some say results are slow and that the clear liquid makes application difficult. Alternative products from Boots and Dr. Scholl are also mentioned.
