What is IPL? Intense Pulsed Light (IPL) therapy works to rejuvenate the skin and aides in reducing the appearance of sun damage, vascular lesions, hyperpigmentation, freckles, broken capillaries, cherry angiomas, and age spots, etc. Master aesthetician Crystal uses the Harmony XL PRO laser from Alma, which is a handheld device, to perform IPL photofacial therapy. The pulsed light from the device is focused on targeted treatment areas to improve the complexion and feel of the skin.
