Aren't dermatological laser treatments always a good thing?
actually A case where receiving the wrong treatment actually makes the skin a worse mess. There are quite a lot.
today 5 Cases of Adverse Effects by Laser I have organized it.
Why is laser treatment a double-edged sword?
Lasers come in a wide variety of types and have completely different uses.
like Bread knives and sashimi knives have different uses. Just as with [a specific type of laser], a laser is effective only when used for the precise indication.
The problem is Receiving indiscriminate laser treatments that are not suitable for my skin condition and purpose The thing is that there are much more than expected.
You can prevent situations where you pay a high price for no effect and are left with only side effects if you know about them in advance.
⚠️ If you receive laser treatment without an accurate diagnosis, side effects such as skin inflammation, pigmentation, and skin sensitivity may occur.
Top 5 Waste of Money Cases: Side Effects by Laser
| # | Laser types | Ineffective situation | Risk level |
|---|---|---|---|
| 1 | Laser toning | Dark pigmentation with distinct boundaries (lentigo/freckles) | Waste↑ |
| 2 | IPL | When irradiating melasma and deep pigmentation | Counterproductive ↑↑ |
| 3 | Fraxel (non-ablative) | Treatment of depressed and pockmarked scars | Limitations of effectiveness |
| 4 | All lasers | Skin condition with severe acne and inflammation | Skin burnout |
| 5 | All lasers | Seborrheic dermatitis and eczema active phase | Risk of worsening |
Laser toning Ineffective on dark pigments
Laser toning is faint pigmentation spread across the face It is specialized in breaking into small pieces.
but Dark pigmentation with clear boundaries, like dark spots or freckles It has almost no effect on.
It’s like trying to break a rock with a squeaky hammer. Even if you perform the procedure 100 times, the rock will not break.
✅ Recommended Cases: Light pigmentation gradually spreading across the face / Early stage of melasma
IPL Shooting at skin with blemishes has a counterproductive effect
IPL has the advantage of simultaneously improving pigmentation and blood vessels with a wide range of wavelengths, but If IPL is applied to skin with deep melasma, the underlying melasma actually surfaces more and hyperpigmentation worsens.
Even among dermatologists, it is considered a "laser that must be used artistically."
⚠️ Individuals with melasma must consult a specialist directly before IPL!
Fraxel (non-ablative) Limited effectiveness on severe scars
Fraxel is a technique that breaks down a laser beam into small pieces and irradiates the skin.
Pores, fine lines, skin elasticity It is effective for, but Repeated non-ablative Fraxel treatments are largely ineffective for deeply indented acne scars that resemble pockmarks.
In this case, you should consider abrasive fractional lasers (such as CO2) or other methods.
ℹ️ Depressed scars → should be classified as ablative Fraxel / Pores and fine lines → as non-ablative Fraxel.
All lasers Avoid during the active phase of acne and inflammation
When the skin has severe acne or a lot of inflammation No matter which laser treatment you receive, it is ineffective and actually makes it worse.
If laser heat stimulation is applied when the skin is in a burned-out state, the skin is completely knocked out, far from regenerating.
The correct order is acne treatment → inflammation soothing → laser.
All lasers The active phases of seborrheic dermatitis and eczema are also the same.
Lasers should be avoided even when seborrheic dermatitis or eczema is severe.
First, after restoring skin condition through medication + moisturizing care You need to receive laser treatment to see results.
Not "Doctors who don't perform laser treatments = quacks," True skill lies in following the proper order with an accurate diagnosis.

✅ Are you currently free of acne, inflammation, or seborrheic dermatitis?

✅ Do I only have a consultation with the manager and proceed directly to the procedure without a consultation with a doctor?

피부 상태에 따라 맞지 않는 레이저가 있다는 점이 인상적이에요. 시술 전 충분히 상담하고 선택하는 게 정말 중요하네요.

칼이라고 하니 무섭네요. 시술 도구가 그렇게 날카로운지 몰랐네요. 마취를 하는 이유를 알겠어요. 과잉으로 시술시 매우 아프겐네요. 하지만 또 미세 박피 제거술이라 두꺼워진 기미성 피부는 잘 안 벗겨져서 피부 탈리 및 재생 효과가 전혀 없나봐요. 아무튼 시술 시에 피부 진피층까지 손상이 되는지 잘 알아보고 시술해야겐네요. 잘되면 매우 좋지만 안되면 속상하고 아플거 같네요.
