Fluorescent Tattoos as Anatomic Markers to Track Trichologic Responses

In the document from November 2018, Dr. Kumar Sukhdeo presented fluorescent tattoos as a novel method for tracking trichologic responses in hair restoration therapy. Traditional methods of localizing scalp areas for assessment either lacked precision or left visible marks that patients found undesirable. Fluorescent tattoos, which are invisible under normal light but visible under a Wood's lamp, provided a permanent yet inconspicuous way to mark the scalp. The process involved creating a tattoo with ultraviolet ink and a sterile needle, with minimal bleeding and optional topical anesthesia. These tattoos allowed for easy re-identification of the treatment area during follow-up visits without the need for permanent visible marks. The technique was low cost, quick, and did not require removal after the study, with low risks of infection and allergic reactions. This method also eliminated the psychological impact of visible tattoos for patients and could be applied to other body areas for dermatologic monitoring.
