Supplementary Material for: Successful removal of 17 tattoos self-administered using black eyeliner ink with QS Nd:YAG 1064nm laser - A case report

INTRODUCTION
Tattooing has a rich historical presence in various human civilizations, with the earliest physical evidence dating back to around 3258 BC. While acceptance of tattoos is increasing in the Western world, negative associations remain. Short-pulsed lasers, such as Q-Switched (QS) or Picosecond lasers, are the gold standard for tattoo removal.
CASE PRESENTATION
This case report discusses the successful removal of 17 amateur tattoos, which were self-administered by a 19-year-old female patient using black eyeliner ink and sewing needles. The tattoos, distributed across her body, including the face and hands, were partially or completely removed over 10 sessions using the QS Nd:YAG 1064nm laser.
CONCLUSION
The factors that influence the efficacy of tattoo removal are highlighted, including tattoo type, location, and coexisting fibrosis. The psychological and social importance of effective tattoo removal is emphasized, particularly for young people seeking to disassociate from past experiences or affiliations.
