This is a procedure note for Underarm Permanent Hair Removal: The principle of achieving lasting results without hyperpigmentation. at Beomgye(Opening Soon) KKEUT Korean Clinic.
Those considering permanent underarm hair removal often have one primary concern.
This is due to the common belief that post-hair removal hyperpigmentation can be a more lasting concern than the hair itself.
Kkeut Korean Medicine Clinic explains the precise principle behind semi-permanent hair removal without hyperpigmentation.

Laser hair removal uses a principle that selectively reacts only to the melanin pigment in hair.
Laser energy is absorbed by melanin, converted into heat energy, and this heat destroys the hair root and follicle.
Hair does not grow back in areas where hair follicles have been destroyed.
The important point is that the laser reacts to melanin in the hair, not the skin.
Because the skin itself is not cut or irritated, skin damage is minimized in precisely calibrated treatments.

Lasers do not affect all hairs simultaneously.
Human hair grows in a cycle of growth, regression, and resting phases, and lasers only act on hair follicles in the growth phase.
Hairs that were in the resting phase during treatment are not destroyed and remain, reappearing in the next growth phase.
This is why stable results for permanent underarm hair removal require accumulating 10 or more treatments at 4-week intervals.
It's not that all hair disappears at once, but rather the hair density gradually decreases with each session.

Semi-permanent Hair Removal: Accurate Understanding is Key
Complete permanent hair removal does not exist medically.
The accurate term for laser hair removal is semi-permanent hair removal.
Even after reaching a state where hair barely grows back after 10 or more cumulative treatments, maintenance treatments every 2-3 months are recommended.
This means that periodic management is necessary to maintain a state of completely reduced hair growth.
Knowing this in advance and starting treatment is key to increasing long-term satisfaction.

Hyperpigmentation occurs because laser energy is partially absorbed not only by the melanin in the hair but also by melanin in the surrounding skin.
Underarms often have a darker skin tone than other areas, so if energy settings are not precise, thermal damage to the epidermis can occur, leading to hyperpigmentation.
To prevent hyperpigmentation, the basic principle is to precisely adjust the output and pulse duration according to the skin tone.
The darker the skin, the lower the output should be, and a different irradiation method is required.

Post-treatment care after permanent underarm hair removal also directly affects the results.
Plucking hair is strictly prohibited.
If you pluck hair during laser hair removal, there will be no hair root for the laser to target, and the treatment will lose its effectiveness.
Shaving is possible from the day after the treatment, but it's best to avoid shaving on the day of the treatment to allow the skin to stabilize.
For 1-2 days after the treatment, avoid activities that generate heat stimulation, such as saunas, strenuous exercise, and alcohol consumption.
Folliculitis may occur, but it will naturally subside with consistent application of a regenerative cream.

Kkeut Korean Medicine Clinic's Unique Hair Removal Design
Kkeut Korean Medicine Clinic's permanent underarm hair removal treatment designs energy settings after analyzing hair thickness, density, and skin tone.
Thick and dark hair has a high melanin content, leading to faster energy absorption.
Setting a longer pulse duration allows heat to be delivered gently, preventing epidermal damage.
Kkeut Korean Medicine Clinic precisely adjusts the pulse duration according to the characteristics of the hair.
Fine and light hair has less melanin, resulting in a lower energy absorption rate.
In this case, energy density is increased or repeated irradiation is used to ensure sufficient heat delivery to the hair root.
Kkeut Korean Medicine Clinic adapts the output method according to the specific characteristics of the hair.
Areas with dense hair, like the underarms, carry a risk of burns due to overheating.
Kkeut Korean Medicine Clinic safely performs treatments by efficiently dispersing energy.

The equipment used at Kkeut Korean Medicine Clinic includes globally verified premium devices such as Apogee and GentleMax.
Apogee features a constant cold air cooling system to minimize skin irritation throughout the procedure.
Choosing this equipment itself is the first condition for achieving semi-permanent results without pigmentation.
At Kkeut Clinic, energy is intensively applied to particularly concerning areas.
Even after the procedure is complete, we do not finalize it until the client gives their final confirmation and approval.
This is an unlimited responsibility system designed to ensure no areas are left untreated.

Frequently Asked Questions
Q. What should I do if I experience pigmentation after permanent underarm hair removal?
A. If pigmentation occurs after permanent underarm hair removal, minimizing sun exposure and thorough moisturizing are top priorities. At Kkeut Clinic, we analyze skin tone and adjust output before the procedure to prevent pigmentation.
Q. How many sessions of permanent underarm hair removal are needed?
A. For permanent underarm hair removal, a minimum of 10 sessions is recommended. Since the laser only targets hair follicles in the growth phase, a sufficient number of accumulated sessions is required to achieve stable results. At Kkeut Clinic, we customize the treatment cycle according to your progress.
Q. How much pain is involved in permanent underarm hair removal?
A. The sensation felt during permanent underarm hair removal is a slight flicking feeling while cold cooling air is sprayed. As sessions accumulate, hair decreases, and pain also reduces.
Q. What's the difference between permanent underarm hair removal and waxing?
A. Waxing removes hair by pulling it out, providing only temporary effects. Permanent underarm hair removal lasers destroy the hair follicle itself, creating semi-permanent results, and in terms of skin irritation, lasers are much gentler.
