What should you know about laser for cherry angioma?

Cherry angiomas are small collections of blood vessels that often look red, purple, or bright pink. A vascular laser delivers energy that is absorbed more strongly by blood than by nearby skin. The spot may darken, swell slightly, or form a light crust before settling. One visit may not give the desired change, especially when an angioma is larger or deeper. The clinician will consider its size, location, colour, and your skin tone when selecting settings.

Have a dermatologist examine a new, changing, bleeding, or unusual red spot before cosmetic treatment. Tell the clinic about medicines, supplements, a tendency to form raised scars, recent tanning, and previous reactions to light-based procedures. After treatment, keep the area clean, avoid picking a crust, and protect it from sunlight as directed. A cool compress can be soothing if the skin feels warm. Discuss alternatives such as [Pulsed Dye Laser Treatment](/treatments/laser-and-energy/pulsed-dye-laser-treatment/) or [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/) if laser is unsuitable.

Contact the treating clinic if redness spreads, pain worsens, swelling becomes marked, or drainage develops. Seek prompt assessment for a spot that changes quickly, repeatedly bleeds, develops an irregular border, or does not resemble your other angiomas; treatment should not delay diagnosis of a different skin lesion.

Ask whether the spot has been examined closely, which laser is appropriate for its colour and depth, what skin reaction is expected, and how aftercare changes with your skin tone. Ask when the area should be reviewed if it does not fade.
