Why does the effectiveness vary depending on the device?

Omokgyo laser hair removal

Hello.

I am Kim Jin-hyun, Medical Director at 유앤아이의원 목동점.

"There are more laser hair removal devices than I expected,

so I don't know which one would be right for me."

Many people have probably had this concern

at least once while researching hair removal.

Since hair removal is a procedure that eliminates hair,

you may think it would produce more or less the same results,

but did you know that the differences can be quite significant?

The appropriate wavelength and energy vary depending on

skin tone, hair thickness, and follicle depth.

Therefore, choosing a device suited to you

is essential for expecting satisfactory results.

So today, for those considering laser hair removal,

I will explain in detail, based on research papers,

how the differences vary by skin type

and recommend suitable devices as well.

1. Why is skin type important

for laser hair removal?

Omokgyo laser hair removal

The principle of laser hair removal is to use light energy

that reacts with the melanin in the hair roots

to remove the hair.

The key concept here is

"selective photothermolysis."

For the procedure to be effective and safe,

the laser must act selectively on the melanin in the hair follicles

without affecting the surrounding tissue.

Since melanin is also present in the skin itself,

darker skin tends to contain more melanin in the epidermis.

This increases the possibility that the laser energy

will be absorbed by the skin's surface rather than the hair follicles.

In other words, even when the same device is used

at the same energy level, the results may differ depending on skin type.

An incorrect choice may also lead to side effects

such as pain or skin damage.

Many people, including East Asians, tend to have

higher levels of melanin and relatively darker skin.

This is precisely why device selection is particularly important

when undergoing laser hair removal.

2. Is there a laser that is safe

even for dark skin?

Then should people with relatively dark skin

give up on laser hair removal?

The answer is no.

I have prepared a research paper

that provides evidence on this topic.

Nd:YAG Laser Hair Removal in Fitzpatrick Skin Types IV to VI

(C. Stanley Chan MD, Jeffrey S. Dover MD,

Journal of Drugs in Dermatology, March 2013)

This paper reports clinical findings showing that

1,064 nm Nd:YAG laser treatment can provide effective

and safe hair removal even for darker skin types.

The reason lies in the characteristics of the wavelength.

As the wavelength becomes longer, light penetrates deeper into the skin,

and a smaller proportion is absorbed by epidermal melanin.

As a result, energy can be delivered to the hair follicles

without damaging the epidermis, even in darker skin.

In particular, the paper explains that using a DCD

(dynamic cooling system) together with a 1,064 nm Nd:YAG laser

further enhances epidermal protection.

Fig 1. a) Before treatment / b) After three sessions of Nd:YAG laser beard hair removal

The images above show a patient with Fitzpatrick skin type IV

before and after three sessions of Nd:YAG laser beard hair removal.

Even after just three sessions, a noticeable reduction in hair

can be seen, while the skin tone and surface also appear

to have remained clear after treatment.

Of course, the number of sessions and the results

may vary depending on an individual's skin condition

and hair density.

3. Choosing the right device

changes the results. ​

The devices used for laser hair removal

can broadly be categorized by wavelength.

Devices using the 755 nm Alexandrite wavelength

respond well to light skin and coarse hair,

while the 1,064 nm Nd:YAG is a long-wavelength laser

that can be used relatively safely even on darker skin,

as explained above.

GentleMax laser hair removal

A laser hair removal device equipped with dual wavelengths,

such as GentleMax, which can use both wavelengths,

allows the appropriate wavelength to be selected

depending on skin type and treatment area,

making effective hair removal possible.

If it also has a cooling system,

it can further reduce pain during treatment

and the risk of heat-related skin damage. ^^

Air cooling continuously cools the skin

throughout the procedure, while the DCD method

sprays cooling gas immediately before the laser is emitted

to protect the epidermis.

In addition, the greater the variety of spot sizes,

the more flexibly the device can be used according to the area,

from narrow areas such as the face to wide areas such as the legs.

Ultimately, what matters is not determining which device is the best,

but identifying which device is appropriate

for your skin type, hair condition,

and treatment area.

Today, I explained the wavelengths

and characteristics of laser hair removal devices.

Even for the same hair removal treatment,

the safety and satisfaction of the procedure

can vary depending on which wavelength

is used with which cooling method.

That is why the question, "Which device is best for me?"

is much more important than asking, "Which device is the best?" ^^

In particular, if you have a darker skin tone

or have experienced skin irritation after a laser treatment in the past,

please remember that you need a thorough consultation

about the device and treatment settings. ^^
