Post infl ammatory hyperpigmentation is a common adverse
manifestation secondary to post trauma or post procedural
healing of the skin. Melasma is a common skin condition
that is multifactorial. Both conditions can be exacerbated
by sun exposure. Many different modalities including
bleaching agents, chemical peels, lasers and light devices
have been used for the treatment of these conditions.
Twenty patients with skin types I-V who presented with
post-infl ammatory hyperpigmentation and Melasma were
treated once every 2–4 weeks with a Q-Switched 1064 nm
Nd:Yag laser. (Revlite – Cynosure Inc.) All twenty patients
had discontinued all other forms of treatments months prior
to the start of the laser treatments. Patients were instructed
to use sunscreen since both conditions are adversely
affected by sun exposure.
Signifi cant improvement was observed in all cases. Mild
temporary erythema immediately after the procedure was
noted in a few of the patients. There were no long term
adverse effects reported.
The use of the Q-Switched 1064 nm Nd:Yag laser is an effective
method for decreasing post-inflammatory hyperpigmentation and Melasma.
