Abstract

Background and objectives: Scalp micropigmentation (SMP) is a useful technique that applies permanent camouflage for hair loss and scarring. However, suboptimal outcomes necessitate removal. To date, there have been no reports of SMP removal with a picosecond laser. In this report, we demonstrate the safety and efficacy of 1064 nm picosecond neodymium yttrium aluminum garnet (Nd:YAG) laser for the removal of SMP.

Study design/materials and methods: This was a case series of four patients who presented with undesirable SMP. Following induction of adequate cutaneous anesthesia, a 1064 nm picosecond Nd:YAG laser was applied to all surface areas with SMP. Post-operative care consisted of 1% dimethicone ointment applied twice daily to the affected areas for 3-7 days. Patients were evaluated after 3-4 weeks and additional treatment sessions were undertaken if necessary.

Results: Clearance of SMP was achieved within 1-3 treatment sessions in all cases. There were no unexpected adverse events.

Conclusion: Picosecond Nd:YAG laser is an excellent treatment option for undesirable SMP. It is safe and effective and typically requires fewer treatment sessions than traditional tattoo removal. Lasers Surg. Med. © 2020 Wiley Periodicals LLC.
