During treatment there will be a bright flash of light from Lumecca, and a sensation on your skin that feels like a light snap from an elastic band. Redness and a slight warming of the skin are normal after treatment and usually subside 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 color change in the vessel which dissipates after a few days.
