Laser Treatment for Pigmented and Vascular Birthmarks
Birthmarks are common and may be present at birth or appear shortly after. While many birthmarks are harmless, some can be cosmetically concerning or may change over time.
At Stephanie Ho Dermatology, we offer advanced laser treatments for birthmark removal, tailored to the type, depth, and colour of the birthmark to achieve optimal and safe results.
Types of birthmarks
Different birthmarks require different laser treatments. The most common types we treat include pigmented and vascular birthmarks.
Naevus of Ota (pigmented birthmark)
Naevus of Ota presents as grey, blue, or brown pigmentation, most commonly affecting one side of the face.
- caused by pigment cells located in the deeper layers of the skin
- may involve the eye or other areas
We use pigment lasers (Q-switched or picosecond lasers) to:
- target deep pigmentation
- gradually lighten the affected areas
- improve overall skin appearance
Early treatment is strongly recommended, as:
- pigmentation is typically lighter and more responsive
- fewer treatment sessions are required
- overall treatment duration is shorter
Most patients require multiple sessions (commonly 5–10 or more treatments) depending on the depth and extent of pigmentation.
Excellent improvement can often be achieved, although a small risk of recurrence may occur over time.
Port wine stains (vascular birthmark)
Port wine stains are red or purple birthmarks caused by abnormal blood vessels in the skin.
- typically present at birth
- may darken, thicken, and become lumpy over time if untreated
We use vascular lasers (pulsed dye laser) to:
- target abnormal blood vessels
- reduce redness
- lighten the birthmark
Early treatment is particularly important, as:
- younger and lighter lesions respond more effectively
- fewer sessions are needed
- progression to thicker, darker lesions can be prevented
Most patients require a series of treatments (often 6–10 or more sessions) for optimal improvement.
Other vascular birthmarks (e.g. haemangiomas)
Certain vascular birthmarks such as haemangiomas may also respond well to vascular laser treatment, depending on the type and stage.
| Type of birthmark | Laser used | Sessions typically required |
|---|---|---|
| Naevus of Ota (pigmented) | Pigment lasers (Q-switched or picosecond lasers) | Commonly 5–10 or more treatments |
| Port wine stains (vascular) | Vascular lasers (pulsed dye laser) | Often 6–10 or more sessions |
| Other vascular birthmarks (e.g. haemangiomas) | Vascular laser treatment | Depending on the type and stage |
Laser treatment for birthmarks
Laser treatment is a safe and effective method for improving many types of birthmarks when performed by an experienced doctor.
Pigment lasers
- Q-switched and picosecond lasers deliver very short pulses of energy
- break down pigment in the skin
- allow gradual clearance over multiple sessions
Vascular lasers
- target blood vessels in the skin
- reduce redness and vascular prominence
Important considerations before treatment
To minimise the risk of complications such as post-inflammatory pigmentation:
- avoid sun exposure and tanning before and after treatment
- use strict sun protection
Before treatment, your dermatologist will discuss:
- expected outcomes
- number of sessions required
- possible downtime
- potential risks such as temporary hyperpigmentation or hypopigmentation

Frequently Asked Questions
How many sessions will I need?
Naevus of Ota usually requires multiple sessions, commonly 5–10 or more treatments depending on the depth and extent of pigmentation. Port wine stains often need a series of 6–10 or more sessions for optimal improvement. Your dermatologist will discuss the number of sessions required before treatment.
Why is early treatment recommended?
Pigmentation is typically lighter and more responsive when treated early, fewer treatment sessions are required, and the overall treatment duration is shorter. For port wine stains, early treatment also helps prevent progression to thicker, darker lesions.
What should I do before and after treatment?
Avoid sun exposure and tanning before and after treatment, and use strict sun protection. These steps help minimise the risk of complications such as post-inflammatory pigmentation.
What are the possible risks and downtime?
Before treatment, your dermatologist will discuss expected outcomes, the number of sessions required, possible downtime, and potential risks such as temporary hyperpigmentation or hypopigmentation.
Which laser is used for my birthmark?
Pigmented birthmarks such as naevus of Ota are treated with pigment lasers (Q-switched or picosecond lasers), while port wine stains and other vascular birthmarks such as haemangiomas are treated with vascular lasers (pulsed dye laser), depending on the type and stage.
