Here we propose to quantify local temperature variations using thermal imaging to assess the effect of dermatological lasers.
OBJECTIVE
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.
CONCLUSIONS
Thermography using an infrared camera could potentially be applied in clinical pharmacology for inflammatory reactions or scarring processes.
