During treatment there will be a bright flash of light from the Lumecca that feels like a light elastic sensation. Redness and a slight warming of the skin are normal after treatment and usually subsides within an hour. Over the next 24-48 hours you may see a darkening of pigmented spots; in the week afterwards the pigmented lesions flake off, leading to an evening out of skin tone. After treating vascular lesions you may see the vein blanch and disappear or a colour change in the vessel which dissipates after a few days.
