摘要：

Here we propose to quantify local temperature variations using thermal imaging to assess the effect of dermatological lasers. Objectives: To quantify the temperature raise induced by laser application and to differentiate the effects of a potassium titanyl phosphate (KTP) laser and an intense pulsed light (IPL). Methods: A randomized comparative study was performed on 10 adult volunteers with symmetrical rosacea treated by KTP laser or IPL. Skin temperature measurements were performed on inclusion, immediately after laser treatment and 3 min after thermal water application, using a high-resolution (0.08 degrees C) infrared thermal video camera. Results: KTP laser treatment induced a significant rise in local skin temperature whereas no significant change was revealed by the IPL treatment. The infrared camera is a reliable and reproducible technique that allows a follow-up of skin temperature without skin contact. Conclusion: Thermography using an infrared camera could potentially be applied in clinical pharmacology for inflammatory reactions or scarring processes.
