Bright nails can be used clinically to treat gray nails, which are caused by fungal infections and are more complex. The application of Brilliant Nail for the treatment of gray nails is effective in some patients, while some patients have average results. There are differences between patients and the extent of the disease, so there is some variation in the effectiveness of the application of this drug. Any medication has side effects, so there are also side effects associated with Bright Nail. It is recommended that patients who have grey nails should go to the dermatology department of a regular hospital for treatment, rather than self-medicating. Please refer to your doctor’s consultation for specific medication.
