If you're considering underarm laser hair removal, you probably have a most pressing question.



'Exactly how many sessions do I need to see results?'







To give you the conclusion first, based on underarms, a minimum of 10 or more sessions is recommended.



This number might seem high, but it makes sense once you understand the reason.



Why Lasers Don't Work on All Hairs at Once



The principle of laser hair removal is to absorb energy into the melanin pigment within the hair, destroying the hair root and follicle.



The key is that the laser is effective only when the hair follicle is in its 'anagen' (growth) phase.







Hair cycles through three stages: anagen (growth), catagen (transition), and telogen (resting).



The laser can only target the anagen phase, and which hair follicles are in the anagen phase is randomly determined each time.



Since it's impossible to make all hair follicles enter the anagen phase simultaneously with one session, a strategy of sequential targeting of the growth phase through repeated sessions is essential.







Why are 10 sessions the standard for underarms?



Underarms have distinct melanin pigment, so the laser response itself is excellent in this area.



However, due to high hair follicle density and individual growth cycles for each follicle, you need to receive treatments consistently for 10 or more sessions to destroy most follicles during their anagen phase.



The interval between sessions is a minimum of 3 weeks, with 4 weeks recommended.



Maintaining the interval according to your skin's exfoliation and regeneration cycle is necessary to protect your skin while effectively targeting new anagen hair follicles.







And there's one more thing you should know.



Laser hair removal is 'semi-permanent hair removal'.



Complete permanent hair removal, where hair never grows back throughout your life, does not medically exist.



Even after completing an intensive course of 10 or more sessions, receiving maintenance treatments once every 2-3 months can help you maintain smooth skin for a long time.







Hair Removal Results That Differ Because It's Kkeut Korean Medicine Clinic



The results of underarm laser hair removal, even after the same 10 sessions, can differ depending on where you receive it.



Kkeut Korean Medicine Clinic individually designs the pulse duration and energy density for each treatment based on hair thickness, density, and skin tone.



For thick, dark hair, we set a high energy density to ensure sufficient heat delivery to the hair root, while for fine, light hair, which has less melanin and is thus harder to treat, we compensate by increasing energy or using repeated pulses.



In areas with dense hair, energy is dispersed to prevent overheating and burns.







Kkeut Korean Medicine Clinic utilizes high-end equipment with proven performance and safety, such as Apogee and GentleMax.



Apogee constantly sprays powerful cold air before and after laser irradiation to minimize skin irritation, while GentleMax uses powerful cooling gas for areas requiring more intensive cooling.







There's another principle unique to Kkeut Korean Medicine Clinic.



We only process a treatment as complete when the client personally verifies the results and gives their OK at the end of the session.



If there's an area of concern, we perform additional focused treatment, and only conclude the session upon the client's final approval.







Frequently Asked Questions



Q. Do I really need 10 or more sessions for underarm laser hair removal?



A. Due to the principle that underarm laser hair removal can only target anagen hair follicles, a minimum of 10 or more sessions is recommended. At Kkeut Korean Medicine Clinic, we adjust the energy for each session, considering hair follicle density and hair condition, to maximize efficiency.



Q. Can I pluck or wax after underarm laser hair removal?



A. Absolutely not. If you pluck hair during underarm laser hair removal, the hair root that the laser needs to target will be gone, reducing the effectiveness of the next session. Shaving is possible starting the day after the treatment.



Q. What is the recommended interval between sessions?



A. Considering your skin's exfoliation and regeneration cycle, it's best to maintain an interval of at least 3 weeks, with 4 weeks recommended. If the interval is too short, skin protection can be difficult; if it's too long, you might miss the anagen hair follicles.



Q. What should I do if folliculitis occurs after underarm laser hair removal?



A. Underarm laser hair removal delivers heat directly to the hair follicles, which can sometimes lead to a folliculitis reaction. Consistently applying a regenerating cream will help it naturally improve over time. Kkeut Korean Medicine Clinic will guide you on post-treatment care methods.
