In such cases, vascular laser treatment such as <a href=\"https:\/\/miragen.clinic\/en\/excel-v\/\">Excel V<\/a> is considered. At our clinic, we treat telangiectasia with the Excel V laser, which supports both the 532nm wavelength suitable for removing red vessels and the 1064nm wavelength suitable for removing blue vessels.<sup><a style=\"color: inherit;\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/24401943\/\" target=\"_blank\" rel=\"noopener\">2<\/a>,<a style=\"color: inherit;\" href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/12006192\/\" target=\"_blank\" rel=\"noopener\">3<\/a><\/sup>  <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">However, when dermatitis is severe, it is advisable to postpone laser treatment temporarily. Applying laser stimulation during active inflammation may worsen the condition. <\/p>\n\n\n\n<figure class=\"wp-block-image alignwide size-large\"><img decoding=\"async\" width=\"2048\" height=\"1152\" src=\"https:\/\/miragen.clinic\/wp-content\/uploads\/2026\/05\/telangiectasia-inline-final-1.webp\" alt=\"Diagram showing the red capillary area reached by the Excel V laser's 532nm wavelength and the blue vein area reached by the 1064nm wavelength, marked with red and blue circles\" class=\"wp-image-11160\" title=\"Excel V 532nm and 1064nm treatment areas\"\/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<hr class=\"wp-block-separator has-text-color has-custom-color-5-color has-alpha-channel-opacity has-custom-color-5-background-color has-background is-style-dots\" style=\"margin-top:var(--wp--preset--spacing--superbspacing-xsmall);margin-bottom:var(--wp--preset--spacing--superbspacing-xsmall)\"\/>\n\n\n\n<h3 id=\"&#xCC38;&#xACE0;&#xBB38;&#xD5CC;\" class=\"wp-block-heading\">References<\/h3>\n\n\n\n<ol class=\"wp-block-list has-custom-color-5-color has-text-color has-link-color has-superbfont-xxsmall-font-size wp-elements-b79c944f1ec75bee40e8d0b4a014a36e\">\n<li><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/39126257\/\" target=\"_blank\" rel=\"noopener\"><em>Nobeyama Y.
