How long does pulsed dye laser treatment take to work for cherry angioma?

The laser targets blood vessels within the red spot. A treated area can look darker, purplish, swollen, or crusted before it becomes lighter. These changes are part of the skin response and do not show the final result. Small cherry angiomas may respond differently from larger or thicker lesions, so a clinician may review the area after it has settled before deciding whether another session is useful.

The treated spot should gradually become less noticeable as the body clears the affected vessels. The exact pace depends on the angioma, the treatment settings, skin type, and how the area heals.

Follow the clinic's aftercare instructions, keep the area clean, and avoid picking at crusts or rubbing the skin. Protect the site from strong sunlight while it heals, because irritation and sun exposure can make temporary colour changes more noticeable. Use only products recommended for the treated skin, and attend the planned review so the response can be assessed safely.

Contact the treating clinic if redness, warmth, swelling, drainage, blistering, or pain is worsening rather than settling, or if you develop a fever. Seek prompt assessment for a spot that bleeds repeatedly, changes in a new way, or was never confirmed as a cherry angioma, since not every red skin mark is the same condition.

Ask how the angioma's size and location affect the expected response, when your review should occur, which aftercare products are suitable, and what change would justify another session.
