Hello.

I’m Wi Yeong-jin from Beauty’s Doctors.

When looking into laser hair removal,

you often come across the name “GentleMax Pro Plus.”

You may wonder:

“Does it all end after one session?”

“They say it uses two wavelengths—what does that mean?”

To summarize, GentleMax Pro Plus

is a hair-removal device that uses two laser wavelengths.

The wavelengths can be considered according to

your hair and skin type and the treatment area,

and because hair grows in cycles,

treatment is usually planned over multiple sessions.

So it is a little different from saying

“all the hair disappears at once.”

Whether it is suitable for your skin and hair

is determined during a consultation and examination,

rather than by the device name alone.

What kind of device is GentleMax Pro Plus?

GentleMax Pro Plus

is a laser hair-removal device by Candela.

Its defining feature is that it combines

a 755 nm alexandrite wavelength

with a 1064 nm Nd:YAG wavelength.

Laser hair removal uses the principle

that laser energy is absorbed by the melanin in hair.

The resulting heat

can be described as being delivered around the hair follicles.

However, the actual treatment method

may vary depending on skin type, hair thickness, treatment area, and skin sensitivity.

During treatment,

the DCD function may also be used

to cool the skin’s surface before the laser is applied.

However, the presence of a cooling function

does not mean that pain or skin reactions

will be the same for everyone.

The sensation during treatment may vary from person to person.

Melanin is the dark pigment found in hair and skin.

DCD is a cooling function

that cools the skin’s surface before the laser is applied.

Why are the two wavelengths used separately?

The 755 nm alexandrite wavelength

is considered for hair removal

because of how it is absorbed by melanin.

It may be considered for thick, dark hair

on typical skin types or for larger treatment areas.

The 1064 nm Nd:YAG wavelength

can be described as a relatively long wavelength.

Depending on the characteristics of the treatment area

or the condition of the skin,

medical professionals may consider using it selectively.

Having two wavelengths means that

the options can be considered differently

according to skin type and treatment area.

However, which wavelength to use

and with what settings must be determined individually.

It is necessary to consider factors such as

whether you have recently been exposed to the sun,

whether your skin is sensitive,

whether your hair is thick or fine,

and whether you have had hair removal before.

Won’t all the hair disappear at once?

There is one point worth addressing here.

Hair grows at different stages.

Not all hair is in the same state at a given time;

hair goes through different cycles,

such as the growth, regression, and resting phases.

Because laser hair removal takes these hair-growth cycles into account,

treatment is often planned over multiple sessions

at set intervals.

The number and spacing of sessions

may vary depending on the treatment area,

hair thickness, skin type, and individual response.

Therefore, rather than assuming that “one session is enough,”

the first step is to establish a plan suited to your condition

during a consultation and examination.

What to check before treatment

Before a laser hair-removal consultation,

it is helpful to check a few things in advance.

You may be asked to consider

which area you want treated,

whether your hair is thick or fine,

whether your skin is sensitive,

and whether you have recently had significant sun exposure.

Even with the same GentleMax Pro Plus device,

the wavelength and settings to consider

may differ from person to person.

The sensation during treatment

and the reaction afterward may also vary individually.

The extent and duration of redness, stinging, or dryness

may differ from person to person.

Before and after treatment,

reducing sun exposure and taking care of moisturization

and sun protection may be helpful.

If you are taking any medication,

or have had hair removal before or have a history of skin conditions,

it is a good idea to mention this during the consultation.

Because everyone’s skin and hair condition is different,

a particular device or method

will not be equally suitable for everyone.

If you are considering a laser hair-removal consultation in Hapjeong,

it is best to first check your current condition through an examination

and then plan the treatment areas and number of sessions.

Detailed information about each treatment

is available on the website.

Frequently Asked Questions

Q. Can GentleMax Pro Plus finish the treatment in one session?

A. Hair grows in different cycles,

so it is difficult to treat all the hair at once.

Treatment is usually planned over multiple sessions

at set intervals,

and the number of sessions

may vary depending on the area and condition.

Q. How are the two wavelengths used separately?

A. The 755 nm and 1064 nm wavelengths

have different characteristics.

After considering your skin type, hair thickness, treatment area,

and whether you have recently been exposed to the sun,

the appropriate wavelength is selectively considered

during the consultation and examination.

Q. How painful is the treatment?

A. A cooling function that cools the skin’s surface

may be used during treatment,

but the level of pain felt

varies depending on the treatment area and individual condition.

If you are sensitive to pain,

it is a good idea to mention this in advance during the consultation.
