Nevus of Ota Laser Treatment: From Principles to Recovery
Nevus of Ota is a bluish dermal pigmented lesion that typically appears around the eye area. This treatment uses laser technology to selectively target pigment in the deep skin layers, aiming to gradually lighten the discoloration. Since the pigment is located deep in the dermis, multiple sessions are often required rather than a single treatment, and both effectiveness and downtime can vary by individual, so consultation with a specialist is necessary.
What Is Nevus of Ota
Nevus of Ota is a bluish or grayish patch that typically appears around one eye, though it is known to sometimes occur on both sides. It is classified as a congenital condition, appearing at birth or developing during growth, and is reported to gradually expand in area or deepen in color with age.
This pigmented lesion is known to originate not from the skin's surface but from abnormal melanocytes (dendritic melanocytes) located in the dermis, specifically in the papillary dermis and upper reticular dermis. Unlike melasma or surface blemishes in the epidermis, the pigment sits in a deeper layer, making it difficult to address through surface care alone—laser-based approaches are often used instead.
Treatment Principle — Selective Photothermolysis
Nevus of Ota laser treatment utilizes Q-switched lasers (using wavelengths such as alexandrite or ruby) to selectively deliver energy to melanin pigment located deep in the dermis. This is based on the concept known as 'selective photothermolysis,' in which extremely short, high-intensity pulses of light are designed to be absorbed primarily by pigment-containing cells.
The pigment that absorbs this energy is known to break down into smaller fragments, which are then gradually cleared through the body's natural metabolic processes. However, since the pigment in Nevus of Ota is located deep in the dermis and tends to be present in larger amounts, treatment is generally carried out gradually over multiple sessions rather than being completed in just one or two.
Expected Changes and Treatment Process
Changes that can be expected from this treatment include the lightening of deep pigment, improvement in overall skin tone and evenness, and refinement of skin texture. However, the degree of perceived results can vary depending on the individual's pigment depth, area, and skin condition, so whether to proceed with treatment and which method is suitable should be determined through consultation with a specialist.
The procedure typically follows this sequence: consultation and skin assessment → cleansing and topical anesthesia if needed → laser application tailored to the area and lesion condition → soothing care and aftercare guidance → return to daily activities. Treatment time is generally known to be around 10–20 minutes depending on the area, and mild to moderate stinging may occur, in which case topical anesthetic cream can be used.
Progress and Downtime
Since the pigment in Nevus of Ota is located in a deep layer, changes tend to appear gradually over multiple sessions rather than immediately. The duration of results and maintenance intervals can vary significantly by individual, depending on factors such as the degree of pigmentation, sun exposure, and skincare habits.
There is generally known to be little to no dedicated recovery period, though slight redness or mild swelling may appear at the treated area, typically subsiding within a few days. In rare cases, temporary pigmentation changes or irritation may occur, so it is important to monitor progress after treatment according to guidance from the treating physician.
Home Care During Post-Treatment Recovery
Immediately after laser treatment, the skin may become temporarily sensitive with reduced barrier function. During this period, it is important to avoid irritating ingredients, ensure thorough sun protection, and support the skin's return to stability through home care focused on soothing and hydration.
Adequate hydration during the recovery period is known to help support the process of calming redness and sensitivity. It is recommended to continue care tailored to the skin's condition in stages, from immediately after treatment through the ongoing recovery period.
Home Care Makes the Difference in Post-Treatment Recovery
Right after treatment, care that soothes the sensitized skin barrier can help, while in the days that follow, care that replenishes deep hydration becomes beneficial. Abiju Cream is formulated to align with this two-step recovery flow: STEP1 Ultra Cera-Rich can be used for soothing redness and barrier care immediately after treatment, while STEP2 Hydro Re-Boosting can support deep hydration during the recovery period. That said, cosmetics are not medications, so it is advisable to consult a specialist about the timing and method of use based on the condition of the treated area.
