Hello.
I’m Kim Ha-won from Beautys Doctor.
“I developed a black spot that wasn’t there before.”
“It seems to have gotten a little bigger.
Can I just have it removed with a laser?”
When people discover a black spot,
they often first think about how to remove it.
However, the first thing we check in the consultation room
is not the type of laser,
but whether the lesion can be removed right away.
That is because a black spot is not a single diagnosis.
From what is commonly called a mole to lentigines, age spots,
and post-inflammatory hyperpigmentation,
different lesions can all appear black.
Even if they look similar on the surface,
their causes and depth within the skin can differ,
so the removal method must also be different.
In particular, if a black spot has appeared recently
or looks different from before,
diagnosis should come before cosmetic removal.
- Dark Color Does Not Necessarily Mean It Is Dangerous

Many black spots
are found to be benign pigmented lesions.
Even if the color is very dark,
it may be an ordinary mole if its size and shape have remained similar over a long period.
Conversely, a lighter color does not necessarily mean
that you can feel completely reassured.
What matters is not just how dark the color is,
but also when it first appeared and whether it has changed recently,
as well as whether it looks noticeably different
compared with other spots around it.
If you compare just one black spot
with images found through an online photo search,
far too many similar images may appear,
which can actually increase your anxiety.
Photos are for reference only
and cannot replace an actual diagnosis.
- If You Notice These Changes, Have It Checked First

When examining a black spot,
the ABCDE criteria are commonly used as a reference.
Look for asymmetry, where the two sides do not match,
an irregular border that is not smooth and appears blurred,
and changes in color, such as multiple shades of brown and black
within a single lesion.
A diameter greater than approximately 6 mm
can also be a clue,
but a small size does not automatically mean it is safe.
Most importantly,
pay attention to change itself—whether the size, shape, or color
continues to change.
If it has noticeably grown over the past few months,
or bleeds without an apparent reason and repeatedly forms a scab,
or if itching and pain persist,
it is better to have it examined before removal.
New spots on the palms or soles,
as well as dark vertical lines appearing beneath a fingernail or toenail,
do not necessarily mean melanoma,
but their pattern of change should be checked.
- How Are These Lesions Distinguished at a Clinic?
First, we check when the black spot appeared,
whether its size or color has changed recently,
and whether there has been any bleeding or pain.
Next, we examine its shape and surface with the naked eye.
If necessary, we use dermoscopy
to observe pigment structures and borders that are difficult to see with the naked eye.
If the lesion is judged to be benign through dermoscopy,
we can determine an appropriate removal method, such as laser treatment or excision,
depending on its location, depth, and degree of elevation.
On the other hand, if findings requiring further differentiation are observed,
we consider a biopsy
rather than immediately burning or shaving off the surface.
A suspicious lesion must be examined under a microscope
for a more accurate diagnosis.
- Why a Suspicious Spot Should Not Be Removed Immediately With a Laser

Laser treatment works by destroying the lesion tissue.
Therefore, if a black spot that requires diagnosis
is removed with a laser first,
there may be no specimen left for a biopsy,
or the lesion’s original appearance may be altered.
If only part of it is removed and the pigment reappears,
it may become more difficult to determine
whether this is a simple recurrence
or a change in the lesion that remained.

That is why the first step in treating a black spot
is differentiation, not automatic removal.
After the lesion has been determined to be benign,
the method should be selected while also considering
the possibility of scarring and the recovery period.
For a suspicious lesion,
it is also medically important to confirm it
using a method that allows a biopsy,
rather than cauterizing it or shaving it off arbitrarily.
- Avoid Picking at or Burning It at Home

Methods such as puncturing it with a needle or picking at it with your fingernails,
or trying to remove it at home using acidic substances or heat,
are not recommended.
If you stimulate only the surface without knowing the lesion’s depth,
burns, infection,
indentation scars, or hyperpigmentation may remain.
Above all, if you damage a lesion that requires further differentiation yourself,
you may delay the timing of diagnosis.
Even if a black spot is cosmetically bothersome,
it is safer to first identify the type of lesion
before deciding on the extent and method of removal.
To Wrap Up
There is no need to worry excessively
simply because you have a black spot.
However, if it has appeared recently
or has become larger, with changes in its color or border,
rather than thinking, “It’s just a mole, so I can have it removed,”
first have it checked to determine what type of lesion it is.
Especially during your consultation,
it is helpful to tell us when you first noticed it
and how quickly it changed.
If you have older photos,
they may also help when comparing them with its current appearance.
Frequently Asked Questions
Q1. If a black spot suddenly gets bigger, should I see a doctor right away?
It is important to determine whether it only appears temporarily swollen over a few days
or whether its actual size and border have changed over several months.
If noticeable changes continue,
it is better to have the lesion checked first
rather than simply scheduling laser treatment.
Q2. Is a spot smaller than 6 mm okay?
Six millimeters is only one reference criterion.
Because changes can also occur in small lesions,
safety is not determined by size alone.
Q3. Will removing a mole leave a scar?
This varies depending on the lesion’s depth, size, and location,
as well as the removal method and the skin’s healing characteristics.
If a deep mole is forcibly removed all at once,
an indentation or pigmentation may remain,
so it is best to discuss the extent and number of treatments during your consultation.
Q4. Can several moles be removed at once?
What is possible depends on the areas and number involved,
as well as the condition of your skin.
If many sites are treated at once,
the burden of wound care also increases,
so treatment may be divided into multiple sessions
with daily activities and the recovery period in mind.
