How many sessions of underarm hair removal will it take to finish?



Hello.

I am Director Wi Young-jin.

When I consult on laser hair removal,

there is a question I hear most often.



How many sessions are needed?

How often should I do it to achieve permanent results?



Today, from a doctor's perspective,

I will talk about armpit hair removal, or permanent hair removal.


I will explain in detail
the cycle and number of armpit laser hair removal sessions.







If you don't know properly,

it will be hard to see results.


Armpit laser hair removal literally aims to

destroy the hair roots for permanent hair removal.


Our body hair grows in cycles of growth, regression, and rest.

Among these, lasers react best to hair in the growth phase.


However, not all hair is in the growth phase at the same time.


So when asked, "Does it all go away after just one session?"

Unfortunately, I have to say NO.



As you undergo multiple sessions,

the hair roots gradually get destroyed, becoming finer and smaller,
and ultimately you will see the permanent hair removal effect you desire.





What is the recommended cycle and number of sessions?



The cycle for armpit laser hair removal is

usually every 4 to 6 weeks.

As a reference, if you have 10 sessions, 75%

and if you have 20 sessions, 95% will be gone.

It may vary depending on individual skin and hair conditions,

so a consultation with a dermatologist is necessary.

Maintaining the cycle of armpit laser hair removal properly is

the key to maximizing the effect.






Even with the same 6 sessions,

the results can be vastly different.



The key to permanent hair removal is not simply the number of sessions.

What really matters is how you receive the treatment.

For example, even if you have the same 6 sessions,

if the equipment used or the power adjustment is not correct,

the effects can significantly drop.

Lasers destroy hair roots with thermal energy.

​If the power is too weak, the desired effect won't be achieved,

and if it's too strong, it may cause irritation or burns on the armpit skin.

That’s why the experience of skilled dermatology professionals is very important.


It needs to be adjusted delicately according to skin condition and hair characteristics

to achieve satisfactory results.





Post-treatment care and

precautions?



The procedure is simple enough to allow you to resume daily activities immediately.

However, because the skin may be temporarily sensitive,

if you follow a few precautions,

it can be managed much more safely and effectively.

1. Please ensure moisturization 💧

After the procedure, the skin may

be dry or rough.

Using a gentle cream or lotion that is non-irritating

to keep the skin moisturized will help significantly with recovery.

If consistent care is maintained,

the permanent hair removal effect will be sustained longer.



2. Don't forget sunscreen 🌞

The armpits may not be visible normally, but

in summer, when wearing sleeveless tops or swimsuits,

they can easily be exposed to sunlight.

Applying sunscreen will help prevent pigmentation

and also prevent the hair from growing back thick.



3. It's better to avoid irritation 🚫

Immediately after the procedure, please avoid hot saunas,

intense exercise, or tight clothing for a while.

Any sweat or friction can cause skin irritation

and inflammation, and any remaining armpit hair

can be stimulated, delaying recovery.




4. Soothe your skin with calming care 🧴

You may feel some redness or slight sting,

and in that case, using a cool calming mask

or cooling products is recommended.

Lowering the skin temperature can speed up recovery

and also reduce unnecessary irritation to the armpit hair.




5. Just leave it alone 🙅‍♀️

Even if the remaining hair after the procedure bothers you,

please do not forcibly pluck or scratch it.

Over time, it will naturally fall out, and

this process must accumulate to achieve proper

armpit hair removal results.

You must adhere to this process to

ultimately obtain the permanent hair removal results you desire.
