Melasma and Dark Spots Laser: Why Does It Keep Getting Darker? Causes Revealed

Hello.

This is Beauty's Doctor, Weeyoungjin.

One day, when you look in the mirror,

has your cheekbone area looked dull and dark,

or have you wondered whether it was a dark spot or melasma?

Melasma is not simply a pigmentation issue,

but a pigment disorder in which

ultraviolet rays, hormones, and lifestyle habits

act together.

I will organize only the key points,

focusing on the parts that are easy to confuse.

How do you tell melasma and dark spots apart?

This is the part people confuse the most.

✔ Melasma

• Fuzzy boundaries

• Spreads broadly like a haze

• Often appears symmetrically on both sides

✔ Dark spots

• Clear boundaries

• Distinct, spot-like shape

• Scattered individually

Simply put,

if it is spread out, it is melasma; if it is dot-like, it is a dark spot.

The reason melasma suddenly became darker one day

Melasma may seem to appear suddenly,

but in fact, it is the result of accumulated irritation

coming to the surface.

The main causes are:

• Sun exposure ☀️

• Hormonal changes (menstruation, pregnancy, birth control pills)

• Stress and lack of sleep

These factors overlap,

rapidly activating melanocytes

and causing the color to deepen.

Can melasma appear in your 20s?

Absolutely possible.

Especially in the following cases,

it can occur regardless of age.

• Genetic factors

• Frequent outdoor activities

• Insufficient sunscreen use

• Taking birth control pills

Recently, as interest in skin care has increased,

many people in their 20s are

detecting melasma early.

Why does melasma concentrate on the cheekbones?

The cheekbones are the most prominent part

of the face.

In other words,

👉 they are the location that receives

the most UV exposure first and most intensely.

So melasma often

appears there first,

and remains darkest there.

The relationship between under-eye melasma, milia, and syringoma

This is a very confusing area.

To get straight to the point,

the causes of occurrence are different.

• Melasma: a pigment disorder (increased melanin)

• Milia/syringoma: benign lesions caused by changes in skin structure

However, because the under-eye area has thin, sensitive skin,

pigmentation and uneven texture can appear together,

making the skin overall look dirtier.

Therefore, treatment must also be differentiated.

• Melasma → toning laser

• Milia/syringoma → CO2 laser

Each requires a different approach

to achieve a clean result.

Do melasma creams work?

This is something many people hope for,

but it is important to understand the role accurately.

Melasma creams are

not meant to erase melasma that is already deeply established,

but rather to

• suppress melanin production

• prevent the color from getting darker

👉 In other words, they are for treatment support and maintenance.

Can vitamin C ampoules be used during the day?

Yes, they can be used.

Vitamin C helps reduce

skin damage caused by UV rays

through its antioxidant effect.

However, there is one condition.

They must be used together with sunscreen.

When do whitening cosmetics start to show effects?

Because the skin has a certain regeneration cycle,

it is difficult to see changes in a short period.

Usually,

it takes consistent use for at least 2 to 3 months

to notice an improvement in complexion.

If you stop in the middle,

it is hard to feel the effect.

What about oral melasma medication?

Tranexamic acid-based medications are commonly used.

They may help improve pigmentation,

but they are not safe for everyone.

In particular,

• blood clot-related conditions

• certain underlying medical conditions

require caution.

👉 Be sure to consult a medical professional

before taking it.

Will folk remedies improve melasma?

These are methods often seen online,

but caution is needed.

In particular, acidic ingredients such as lemon or vinegar

can damage the skin barrier and

• increase irritation

• worsen pigmentation

Unverified methods are

best avoided.

Laser toning: how many sessions are needed to see results?

Melasma treatment is not something that ends in one session,

but rather requires ongoing management.

Generally,

• at 1- to 2-week intervals

• after 10 or more sessions

many people notice a visible change.

👉 What matters is

“consistency,” not intensity.

It seems like my melasma got darker after the laser

Sometimes, after the procedure,

the color may temporarily appear darker.

This may be

• a temporary reaction, or

• pigmentation caused by excessive irritation

👉 Because it is important to distinguish between the two,

it is best to receive a consultation in such cases.

Is daily life possible after the procedure?

Laser toning is

a relatively low-burden procedure.

• Almost no pain

• You can wash your face immediately after the procedure

• Makeup is possible

👉 In most cases, it does not significantly interfere with daily life.

When melasma and seborrheic keratosis are both present

They often appear together.

In this case, rather than solving it with just one method,

treatments suited to each condition should be used together.

• Melasma → toning laser

• Seborrheic keratosis → removal laser

👉 A different approach is needed.

Melasma prevention and lifestyle habits

Melasma is just as much about prevention and management

as it is about treatment.

✔ Sun protection (including indoors) ☀️

✔ Adequate sleep

✔ Stress management

✔ Maintaining hydration

In particular, ultraviolet rays

through UVA that enter through windows can also have an effect,

so care is needed even indoors.

The relationship between pregnancy, birth control pills, and melasma

Hormonal changes have a major impact on melasma.

• Melasma during pregnancy → may partially improve after childbirth

• Birth control pills → may stimulate melanin

👉 Because there are individual differences,

if symptoms are present,

it is better to adjust them through consultation.

How to prevent recurrence after treatment

Post-treatment management is key for melasma.

In particular,

the 3 months after treatment are the most important.

• Sun protection

• Moisturizing

• Maintenance treatment

If this process is not followed,

it often comes back.

Melasma is not a condition that can be removed all at once,

but a pigment disorder that requires steady management.

The earlier you manage it,

the shorter and less difficult the treatment period becomes.

If it is hard to judge on your own,

accurately checking your current condition through

professional consultation is

the best place to start.
