Prospective Study of 532-nm Picosecond Laser for the Treatment of Pigmented Lesions of the Face and Dorsal Hands.

Background: Pigmented lesions from chronic UV photoaging are extremely common on the face and hands.

Objective: To evaluate the safety and efficacy of a 532-nm picosecond laser for these types of pigmented lesions.

Methods: This was a single-center, prospective, open-label clinical trial.

Efficacy and Safety of Intense Pulsed Light With a KTP/PDLlike Filter for the Treatment of Facial Telangiectasias.

Background: An intense pulsed light (IPL) narrowband "KTP/PDL-like" filter (525–585 nm) may combine the tolerability of the IPL with the precision of KTP and PDL lasers. This study evaluated the impact of IPL with a KTP/PDL-like filter on telangiectasias.

Methods: This was a single-center, prospective study of 17 subjects with facial telangiectasias and skin types I–III.
