Nevus of Ota:
Nevus of Ota is a benign (non-cancerous) growth of pigment cells in the deeper layers of the skin. It typically appears in childhood and is more common in Asians, particularly women. While not harmful, many people seek treatment due to cosmetic concerns.
Available skin treatments for nevus of ota
There are several treatment options available, each with its own benefits and potential risks, including the possibility of scarring. These treatments include:
Cryotherapy:
This method involves freezing the pigmented area to destroy the melanocytes. It is effective but may lead to scarring and changes in skin texture.
Lasers:
Various laser treatments, particularly pulsed Q-switched lasers, have been found to be highly effective. These lasers target and destroy the pigment-producing cells, reducing the appearance of the nevus.
Surgery:
Surgical removal of the lesions is an option, but it carries a higher risk of scarring and is typically reserved for severe cases.
Dermabrasion:
This procedure involves mechanically exfoliating the top layers of skin, which can help reduce pigmentation but may also result in scarring.
Chemical Peels:
Chemical peels use acidic solutions to remove the top layers of skin, reducing pigmentation. This treatment can be effective, but may cause temporary irritation and peeling.
Topical hydroquinone-based bleaching agents:
These creams can lighten the skin pigmentation over time, although they are generally less effective than other treatments and may take longer to show results.
The effectiveness of Q-Switched Lasers
The Q-switched Nd:YAG laser is a powerful tool for treating Nevus of Ota. It works by delivering short bursts of intense light that target and break down the pigment cells causing the discolouration. This treatment is:
Effective:
Studies show significant improvement in pigmentation with minimal side effects.
Safe:
Q-switched lasers are well-tolerated, with minimal risk of scarring.
Precise:
The laser targets specific areas, minimizing impact on surrounding healthy skin.
However, it’s important to note that re-pigmentation can occur within 2 to 3 years post-treatment, necessitating follow-up sessions.
What to expect with laser treatment
Most patients require multiple treatment sessions, spaced at monthly intervals, for optimal results. You may experience some discomfort during the laser treatment, which can be managed with topical anaesthetic. Following treatment, some temporary side effects like mild swelling or redness may occur, but these typically resolve quickly.
Post-treatment care
After undergoing treatment for nevus of Ota, proper skincare is crucial to prevent hyperpigmentation and maintain results. Here are some key tips:
Avoid direct sunlight:
Minimize exposure to direct sunlight, especially during peak hours.
Use broad-spectrum sunscreen:
Apply a high SPF broad-spectrum sunscreen daily to protect your skin from UV damage.
Follow up with your doctor:
Regular check-ups with your dermatologist will help monitor your skin’s condition and address any concerns promptly.
