Treatment for a Blue Facial Spot (Nevus of Ota): Laser Principles, Number of Sessions · Post-Treatment Care

Hello.

I’m Wi Young-jin from Beauty’s Doctor.

Some people have subtle blue-gray or brownish spots

around the eyes or temples

that have remained there

for a long time.

They may look noticeable even when covered with makeup,

or seem to darken over time,

which may lead them to look into treatment for nevus of Ota.

However,

nevus of Ota is known to be associated

with pigment cells deep in the dermis,

rather than in the epidermis.

It is helpful to understand first

that the approach may differ

from that used for ordinary melasma

or blemish care.

Today, I’ll calmly organize

the background behind the development of nevus of Ota,

how treatment for nevus of Ota

is generally carried out,

and how to care for the skin afterward.

The course of treatment and the time required

may vary depending on skin type

and the depth and extent of the spot,

so please consider the information below

for reference only.

3-Line Summary

1. Nevus of Ota is a blue-gray spot

that appears around the eyes and temples

and is known to be associated

with pigment cells in the dermis.

2. Treatment for nevus of Ota generally uses lasers

to break down the pigment,

and is often carried out

over multiple sessions.

3. Individual differences may occur

in the course and time required

before and after treatment,

so it is necessary to have the condition

assessed during a medical consultation.

1. Why does nevus of Ota develop, and why might treatment be needed?

Nevus of Ota is a blue-gray or brownish spot

that appears around the eyes, temples,

and the sides of the forehead.

It may be visible from birth,

or may gradually appear

around puberty,

according to reports.

Its association with the proliferation

of melanocytes located in the dermis

is a characteristic that distinguishes it

from epidermal pigment disorders.

It is not uncommon for people to seek medical care

because of its location or extent,

rather than solely as a cosmetic concern.

Dermal pigment is deeper

than epidermal pigment,

and is known to fade naturally

more slowly.

Rather than simply observing it,

it may be helpful to first receive

an accurate diagnosis.

2. How is treatment for nevus of Ota carried out?

Treatment mainly uses equipment

such as picosecond lasers

or Q-switched lasers,

which selectively break down pigment.

Because the pigment is located deep in the dermis,

it is often treated over multiple sessions

at intervals,

rather than being completed in a single treatment.

The interval and number of sessions

may be determined differently

depending on the depth, extent, and color

of the spot.

Therefore, rather than shortening the intervals excessively

or adjusting the pace

based on personal judgment,

it is preferable to establish a schedule

after a medical consultation.

Even if the pigment seems to fade slowly,

its characteristics in the dermis

may require observing the course

over time.

3. What should be checked before proceeding?

Rather than repeating treatments

at short intervals,

it is important to check the skin’s recovery

before adjusting the schedule for the next session.

To avoid starting treatment immediately

while mistaking it for another pigment disorder,

first confirm whether it is nevus of Ota.

It is also important not to overlook

sun protection after treatment.

Use sun protection when going outdoors,

and when the skin is sensitive,

it is better to reduce unnecessary irritation.

As such, treatment for nevus of Ota

is not a one-time process

that ends after a single session,

but is more like a course that continues

while monitoring the recovery status.

4. How should the skin be cared for after treatment?

Immediately after treatment, the area may feel

more sensitive than usual,

so you should pay additional attention

to sun protection.

Pigment may appear darker again,

or continued pigmentation may occur,

which is known to be associated

with sun exposure.

It is better to avoid for a while

frequently touching the treated area

or repeatedly irritating it

with your hands.

Please also postpone visits to environments

with intense heat, such as hot saunas and bathhouses,

during the period recommended by your provider.

During the recovery period after treatment for nevus of Ota,

make moisturizing and sun protection

your basic routine,

and observe whether there are

any reactions different from usual.

If discomfort gradually worsens

or an unusual reaction continues for a long time,

contact the medical institution

where you received treatment

to have it checked.

Wrapping Up

Because nevus of Ota involves

pigment in the dermis,

individual differences may occur

in its course and the time required.

Even when the same treatment method is used,

reactions may differ

depending on the depth and extent of the spot

and the individual’s skin type.

Rather than making a judgment based only on information online,

it is necessary to have your current condition assessed

through a medical consultation

and determine an approach

that suits you.

Reviewing the condition carefully

from the diagnostic stage onward

may help you make a specific plan

rather than remain with vague anxiety.

Frequently Asked Questions

Q1. Does nevus of Ota naturally become lighter with age?

There are differences between individuals,

so it is difficult to give a uniform answer.

Because of the characteristics of dermal pigment,

changes may occur slowly,

so it is better to have the condition

assessed through a medical consultation.

Q2. How many treatment sessions are usually needed?

The required number of sessions may vary

depending on the depth, extent, and color

of the spot,

so individual differences can be significant.

It is common to adjust the treatment interval

and number of sessions

while monitoring the course after diagnosis.

Q3. Can the pigment become darker again after treatment?

Depending on sun exposure

and how irritation is managed,

pigment may appear darker again,

or the pattern of pigmentation may change.

After treatment, it is better to continue

sun protection and care that reduces irritation

consistently.

Q4. How can nevus of Ota be distinguished from ordinary melasma?

Because it may be difficult to distinguish them

by appearance alone,

rather than relying only on self-diagnosis,

it is better to have it accurately assessed

at a medical institution.

Considering the spot’s location and color,

as well as when it first appeared,

may help distinguish the cause

and determine the appropriate direction

for medical care.
