Q-Switched Nd:YAG 1064-nm Laser for the Treatment of Acne-Induced Postinflammatory Hyperpigmentation

The document presents a pilot study conducted by Gabriela Fagundes and colleagues, which investigated the use of fractional infrared technology for treating cervical laxity. The study included four female patients with moderate to severe cervical laxity who had not undergone previous surgery. They were treated with three sessions using energies between 80 and 100 J, with a pulse duration of 10 seconds and 5 seconds of precooling. The results, measured by pretreatment photographs and histology on day 0 and day 120, showed good improvement in the laxity and thickness of the cervical area without any collateral effects. The study concluded that fractional infrared technology is effective and safe for treating cervical laxity, suggesting that further research with more participants is needed for significant statistical results. No commercial support was identified for this study.
