Hello.
This is Wi Young-jin from Beauty's Doctors.
When consulting about laser hair removal,
the question I hear most often is:
How many sessions do I need?
How often do I need to do it to get a permanent effect?
Today, from a doctor’s perspective,
I’ll explain in detail about underarm hair removal, that is, permanent hair removal,
including the axillary laser hair removal cycle and number of sessions.
If you do not understand it properly,
it is difficult to see results.

Axillary laser hair removal literally
aims for permanent hair removal
by destroying the hair follicles.
Hair on our body grows by repeating the anagen, catagen,
and telogen phases.
Among these, lasers
respond best to hair in the anagen phase.
However, not all hair is in the
anagen phase at the same time.
So if you do it just once,
do all the hairs disappear?
Unfortunately, the answer is NO.
Usually, multiple sessions are needed.
As the treatments continue,
the hair follicles are gradually destroyed,
becoming finer and fewer,
and eventually you can achieve the
desired permanent hair removal effect.
What is the treatment cycle
and how many sessions are needed?

The axillary laser hair removal cycle is
usually performed at intervals of 4 to 6 weeks.
For reference, in numerical terms:
after 10 sessions, 75%
after 20 sessions, 95% will be gone.
There may be differences depending on
each person’s skin and hair condition,
so a dermatology consultation is essential.
Properly following the axillary laser hair removal cycle is
the key to maximizing results.

Even with the same 6 sessions,
the results can be worlds apart

The key to permanent hair removal is not simply
how many times you receive it.
What really matters is
how it is done.
For example, even if you receive 6 sessions,
if the equipment used or the output settings are not properly adjusted,
the effect can drop significantly.
Lasers destroy hair follicles
using thermal energy.
If the output is too weak,
you will not get the desired effect,
and if it is too strong,
it can irritate the underarm skin or
cause burns.
That is why the experience of an
experienced dermatology medical team is really important.
You need delicate adjustments tailored to
your skin condition and hair characteristics
to achieve satisfying results.
Post-treatment care and
precautions?
It is a simple procedure that allows you to return to daily life immediately.
However, because your skin may become temporarily sensitive,
if you follow just a few rules,
you can manage it much more safely and effectively.
- Be sure to moisturize 💧
After the procedure, the skin may
feel dry or tight.
Using a gentle, non-irritating cream or lotion
to keep it moisturized
is very helpful for skin recovery.
With consistent care over time,
the permanent hair removal effect is maintained longer.
- Don’t forget sun protection 🌞
Although the underarms are not usually visible,
in summer, when wearing sleeveless tops or swimwear,
they can be easily exposed to sunlight.
Applying sunscreen can help prevent pigmentation
and also help keep the underarm hair
from becoming coarse again.
- It is better to avoid irritation 🚫
Right after the procedure, please avoid hot saunas,
strenuous exercise, and tight clothing for a while.
Sweat and friction can cause skin irritation and
inflammation, and if the remaining underarm hair is
stimulated, recovery may be delayed.
- Soothe the skin with calming care 🧴
You may feel redness or slight stinging,
and in such cases, a cool soothing pack or
cooling product can help.
Lowering the skin temperature speeds up recovery
and can also reduce unnecessary stimulation of underarm hair.
- Leave it alone 🙅♀️
Even if the remaining hair after treatment bothers you,
do not forcefully pluck or scratch it.
Over time, it will naturally shed,
and this process needs to accumulate for proper
underarm hair removal results.
You need to follow this process carefully
in order to ultimately achieve the
desired permanent hair removal result.
