Nevus of Ota
What is Nevus of Ota?
Nevus of Ota is a birthmark that usually occurs on one side of the face. It commonly affects the skin around the eyes, cheeks, forehead and nose. It may also be present on the whites of the eyes or on the mouth.
It may appear blue-grey or brown, depending on how deep the pigmentation is in the skin. More superficial pigments appear brown whilst deeper pigments have a bluish tinge due to the way light is reflected in the skin.
Roughly half of all nevus of Ota cases are present at birth, while the rest typically develop during adolescence. These lesions can remain unchanged throughout life, but can also darken over time due to sun exposure.
Do I need to treat it?
Nevus of Ota is harmless and can be left alone. However, if it is cosmetically undesired and impacting your quality of life, you may choose to receive treatment for it.
In certain cases where there is eye involvement, there may be a risk of increased intraocular (eye) pressure and it is recommended to followup with an eye doctor.
How do I treat it?
Nevus of Ota treatment with 1064 Nd:YAG pico laser is the most effective treatment modality. Lasers work by breaking down dermal pigments. The 1064 Nd:YAG pico laser is able to reach deep dermal pigments in Nevus of Ota. Once the pigments are broken down, the smaller particles are then naturally cleared by the body.
Pico laser is a safe and effective treatment for Nevus of Ota. With increased efficacy and safety with laser systems, you can see an improvement within a few treatment sessions. Usually 5 to 10 sessions are needed to treat Nevus of Ota.

What do I need to take note of?
For almost all laser treatments, there is a risk of post-inflammatory hyperpigmentation and hypopigmentation.
