Hello.
This is Beauty's Doctor, Wi Young-jin.
Among those considering hair removal,
“Why do people say to do it in winter?”
“Is the difference between devices really that big?”
Many people have these questions.
In particular, laser hair removal is
not simply a procedure to remove hair,
but one that requires considering
cycle, wavelength, and skin condition
all together.
So today,
based on GentleMax Pro Plus,
I will explain the key Q&A about hair removal
in a way that is a little easier to understand.

Why is winter hair removal effective?
Winter hair removal is
actually one of the more effective seasons.
The reason is simpler than you might think.
As your skin tone becomes lighter than in summer,
laser response improves,
and because there is less UV exposure,
the risk of post-procedure pigmentation is reduced.
Also, in environments with lower temperatures
and drier skin,
inflammatory reactions themselves
tend to occur less often.
So if you want to get ready for next summer
with a cleaner result,
starting in winter is
the most efficient choice.
755nm vs 1064nm, what’s the difference?
This is not a tip or a difference in the device,
but a difference in “laser wavelength.”
755nm has a high melanin absorption rate,
so it is effective for thin, relatively shallow hair.
In contrast, 1064nm
penetrates deeper into the skin
and works on thick, deep hair.
In particular, for deep and strong follicles
such as men’s beards,
1064nm is more suitable.
Because GentleMax Pro Plus can use
both of these wavelengths
in one device,
it allows customized treatment.
I’ve had 10 hair removal sessions, so why is hair still growing?
This is a normal process.
Hair repeats a cycle of
growth phase → regression phase → resting phase,
and laser responds well only to hairs in the growth phase.
The problem is that not all hairs are
in the growth phase at the same time.
So hair removal is carried out by repeating sessions
and gradually reducing density.
Usually, after 10 or more sessions,
people start to feel that hair is “almost not growing,”
and after about 15 sessions,
it often decreases to just one or two strands.
Is it really “permanent hair removal”?
If you look at individual hairs,
it is correct to say they are permanently removed.
However, when looking at all hair overall,
you can think of the density as decreasing
by about 20% at a time.
So as time passes,
some very fine hairs may appear again,
and in that case,
1 to 2 additional maintenance sessions are performed.
Does the effect decrease over time?
Hair removal should be viewed not as a “count” concept,
but as a “ratio” concept.
For example,
it goes from 100 hairs to 10 fewer,
and from 10 hairs to 1 fewer.
So,
in the beginning the effect feels large,
and as time goes on,
the changes may feel slower,
which is a normal pattern.
Why do many people start hair removal in winter?
Winter is the season
when the risk of pigmentation
and the possibility of erythema
are both lowest.
Also,
because you can create a state with much less hair
before spring and summer arrive,
it is also the most efficient timing.
Why the device matters for hair removal

Laser hair removal is
not something where “a good device is enough.”
However, there are definitely differences
in device performance.
The biggest differences are
output stability and the cooling system.
GentleMax Pro Plus uses dual wavelengths (755 + 1064),
delivers output quickly and deeply,
and the DCD cooling system
helps reduce pain and the risk of burns.
It also allows precise adjustment of energy
to match skin tone and hair condition.
Why choosing the right clinic matters

Laser hair removal is a procedure
whose results can vary greatly depending on the settings.
Even with the same device,
energy intensity
irradiation speed
overlap interval
all of these factors
affect the result.
Problems such as burns, pigmentation,
and insufficient effectiveness
mostly arise from poor setting control.
So rather than the device alone,
treatment experience and know-how
are much more important factors.
Why energy values differ by area
Hair removal must be approached
differently depending on the area.
For example, the underarms have
relatively shallow hair,
so treatment is often performed mainly
with the 755 wavelength,
while deep, thick hair such as men’s beards
is treated with 1064nm
using stronger energy.
Also,
skin tone,
recent UV exposure,
and treatment interval
all of these factors
mean the energy value is adjusted each time.
The core principle of the dual-wavelength system
The key point of GentleMax Pro Plus is
that it selects between two wavelengths
depending on the situation.
755nm
has excellent melanin absorption,
so it is effective for removing thin hair,
and
1064nm
reaches deep follicles,
which makes it advantageous for removing thick hair.
Because both can be used
in one device,
precise hair removal tailored to skin type
and hair condition is possible.
Laser hair removal is
not simply a procedure to remove hair,
but a process that considers
cycle, wavelength, and energy adjustment
all together.
So,
while choosing the device is important,
what matters even more is
a treatment method designed to fit the individual.
Thank you for reading this long post.
