Abstract
Background: This study aimed to develop the algorithm for choosing both effective and safe mode of dual-wavelengths copper vapor laser (CVL) photodestruction of dilated dermal vessels in PWS for different skin phototypes. This study is expected to assess the safe parameters for CVL treatment.
Methods: We used the multilayered skin model with different melanin content for simulation. The calculation of the vascular component’s selective heating with CVL radiation at the green and yellow wavelengths for different skin phototypes was performed with Matlab mathematical programming system and its application Femlab for solving partial differential equations using the Finite element method.
Results: We determined the location depth and size of blood vessels that could be selectively heated to the coagulation temperature for different skin phototypes.
Conclusion: CVL can selectively heat 15-300 mcm vessel diameters that correspond to the PWS vessel diameter range. CVL fluence values need to be reduced almost twice for the IV skin phototype than the II skin phototype. The maximum depth of the vessels’ location also decreased for dark skin phototypes.
