Iridex diode lasers make treating vascular pigmented lesions easier and more effective than ever before. Three different lasers have been designed to treat lesions at different levels within the skin. Each laser works by delivering energy directly to the target vessel(s), which then collapse and are naturally reabsorbed by the body. Results are visible after a single treatment; lesions grey immediately and flake off within 7-10 days. Nevertheless, two to three treatments are recommended for most patients to achieve the best possible long-lasting results.
