Low-energy, multi-wavelength long-pulse diode laser for post-sclerotherapy hyperpigmentation in Fitzpatrick skin type III-IV: A case series
Abstract
Persistent post-sclerotherapy hyperpigmentation is a frequent concern in patients with Fitzpatrick skin types III–IV due to higher melanocytic activity. This study assessed the effectiveness of a low-fluence, multi-wavelength long-pulse diode laser (755/810/1064 nm) in ten Korean patients with post-sclerotherapy hyperpigmentation persisting for more than 3 months. Using a gentle protocol with contact cooling over 3–6 sessions, patients achieved an average of 75% pigment clearance with minimal side effects. No scarring, hypopigmentation, or recurrence was observed after 3 months. This laser approach appears to be a safe and effective treatment for post-sclerotherapy hyperpigmentation in melanin-rich skin.
