Simulation of Temperature Distribution in SkinTissue for Acne Treatment by Pulse Laser inDifferent Doses to Prevent Skin Burning

Different treatment methods, such as exfoliation, micro-needling, etc., treat acne depending on theskin type and other determining conditions. One of the most influential and best treatment methodsfor acne is lasers. In this article, the mathematical model of hyperbolic heat transfer of body tissue bylaser has been subjected to dynamic analysis to avoid damage. Dynamic analysis, such as the system'stime series and heat transfer method on the skin, have been done in this study. By analyzing the heattransfer system, we numerically studied the required wavelength and dose of the laser and the effectof the thermal relaxation time (𝜏) on the tissue. Analytical results showed that for the pulse width valueused (۲۰۰ 𝜇𝑠), the temperature profiles obtained from the hyperbolic heat transfer equation (HHTE)during the cooling phase (i.e. when the laser is turned off), the temperature evolution of the HHTE asThe width is different for different values of 𝜏. Also, dynamic behaviours of the model, such as spiralwaves, were performed to reduce pain and laser treatment on the skin. Identifying the emotionalbehaviours of the heat transfer model produced by the laser to eliminate acne on the skin helps toreduce pain and provide better treatment.
