Hello, this is Kang Bu-kyung, chief director of Wangsimni UI Dermatology Clinic.

"The blemishes that keep bothering me every time I look in the mirror..

I hear laser treatment can make them go away,

but does it really work?"

You probably clicked on this article while worrying about something like this.

Many people are stressed by pigmentation such as melasma, lentigines, and freckles.

However, if you undergo laser treatment without thinking it through, you may end up with an even bigger concern.

So today, I’d like to talk about why pigmentation treatment should be chosen carefully, and about the "this" that is needed for a thorough diagnosis.

If you are considering pigmentation treatment, please read to the end.

Why shouldn’t you

get laser toning without thinking it through?

To get straight to the point, the reason you should not get a procedure without thinking it through is...

Even though pigmentation lesions may look similar on the surface, the disease names are different and the depth at which the pigmentation is located also varies.

Some pigmentation is shallow in the epidermis, while some is located deep in the dermis.

So the laser wavelength used must also differ depending on the depth of the pigmentation.

If the procedure is done with the wrong laser, not only may it fail to produce results, but side effects may also occur.

Therefore, careful consideration is needed regarding which laser device to use, how to set it, and how the procedure should be performed.

At this time, one of the representative side effects of laser toning is "rebound hyperpigmentation."

This refers to the phenomenon in which pigmentation becomes darker and spreads more widely after treatment. In addition, the skin may become red, and burns or scars may occur,

and repeated procedures can also make the skin dry and sensitive.

So, once again, to reduce the possibility of such side effects occurring, it is important to make a careful diagnosis from the beginning and establish a treatment plan.

Also, after laser treatment, the skin becomes very sensitive, so you must follow precautions such as moisturizing care and avoiding ultraviolet rays.

What is "this" for a thorough diagnosis?

In fact, even for a dermatologist, diagnosis by visual inspection alone has its limitations.

It is difficult to carefully determine how deep the pigmentation is and how it is distributed.

In such cases, a skin diagnostic device called "Mark-Vu" can be helpful.

Mark-Vu photographs the skin in four different modes—glossy light, natural light, polarized light, and ultraviolet light—allowing it to check areas that are hard to see with the naked eye.

It can also distinguish between brown and red pigment types, enabling a more detailed assessment of the pigmentation condition, and it can analyze the skin from multiple angles using a 3D viewer.

Thanks to this, it can detect hidden skin damage or early-stage pigmentation, which helps create a more precise treatment plan.

So far, I have explained the precautions to take during pigmentation treatment and the importance of a thorough diagnosis for those visiting a dermatology clinic near Sangwangsimni Station.

Ultimately, what matters is not simply "how many times you had laser toning," but "how well the procedure was tailored to you."

Even if you do not visit our clinic, I hope you will go to a place that provides precise diagnosis of your skin and customized treatment.

Thank you for reading this long post. This has been Chief Director Kang Bu-kyung. ^^
