BC02 Efficacy and safety of picosecond Nd-YAG laser for tattoo removal in Asian patients: a way to look forward

Abstract Picosecond neodymium-doped yttrium aluminium garnet (Nd-YAG) lasers have emerged as the leading technology for tattoo removal due to their shorter pulse lengths and are considered better than other nanosecond lasers. The aim was study efficacy adverse effects of a picosecond quality-switched (QS) Nd-YAG laser in case series 15 Asian patients removal. Fifteen with black- blue-coloured tattoos were recruited All treated 1064-picosecond QS laser. A single session one pass performed using spot size 4 mm, fluence 0.5–1 J cm–2 frequency 6–10 Hz. parameters adjusted based on type patient’s skin type. Patients at 4–6-weekly intervals. clearance pigmentation local reactions evaluated clinical photographs dermoscopy, done each sitting. At end, both physician assessed tattoo. For patient assessment, visual analogue scale (VAS) used. To assess treatment by physician, rate scored 5-point (0–4) (4: ≥ 70% removal, excellent improvement; 3: 50% < 70%, marked 2: 30% 50%, moderate 1: 10% 30%, mild improvement 0: 10%, no effect). asked satisfaction (0 = dissatisfactory, 10 satisfactory) pain pain, worst pain) VAS.
