Clinical Details

Official title: Effect of Topical Corticosteroids on the Incidence of Postinflammatory Hyperpigmentation Following Q-switched Nd:YAG 532 nm Laser for Treatment of Facial Lentigines - A Pilot Study

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Investigator), Primary Purpose: Treatment

Primary outcome: The incidence of post inflammatory hyperpigmentation

Secondary outcome:

Side effects of topical steroid

The patients satisfaction

Detailed description:

- The incidence of post inflammatory hyperpigmentation (PIH) after treating lentigines

with Q-switched Nd: YAG laser was 78. 3%.

- It has been found that the incidence of PIH decreased to 40% after applied topical high

potency steroid 2 days after the laser treatment.

- By these anti-inflammatory and anti-PIH effects of the high potency steroid, the

investigators aimed that the application of steroid 2 days before and 2 days after the laser treatment would be better reduction in the incidence of PIH after Q-switched Nd: YAG laser.
