Laser Hair Removal in Seoul.
General information on laser hair removal using the Soprano Titanium multi-wavelength platform, and how LOUAVE Dermatology Clinic approaches it. Hair color, skin tone and treatment area are assessed first, since these factors — more than any single setting — determine which wavelength combination and course length actually fits your case.
This page focuses on general laser hair removal planning. LOUAVE also publishes a Laser Tattoo Removal guide for readers comparing the different laser platforms used across the Hair & Tattoo Removal category.
Hair & Skin Assessment
Hair grows in cycles, so sessions are spaced to catch hairs entering their active growth phase, with spacing depending on the treatment area.
Sessions typically involve mild warmth and redness around treated follicles, generally settling within a few hours to a day.
Hair color and skin tone respond differently to different wavelengths, so the doctor selects the combination for your specific case rather than a default setting.
Understanding Laser Hair Removal
Why the growth cycle matters more than how much hair is visible today.
Laser hair removal works by targeting melanin in the hair follicle, heating it enough to disable future growth while sparing surrounding skin. Only hairs in their active growth phase (anagen) respond well, and since hairs cycle through growth, transition and resting phases at different times, no single session can catch every hair — repeated sessions are needed to treat hairs as they enter the active phase.
Very light blonde, white or grey hair contains little melanin and responds poorly to laser regardless of platform or wavelength. This is a genuine limitation of the technology, not a matter of trying harder or adding more sessions indefinitely — it is reviewed honestly at consultation rather than promised away.
Because Soprano Titanium combines three wavelengths (755nm, 810nm and 1064nm) in one in-motion platform, the combination used is chosen at consultation based on hair color, hair thickness and skin tone. The longer 1064nm wavelength is generally favored for medium-to-deeper skin tones, since it is less strongly absorbed by surrounding skin melanin, reducing pigment-change risk.
The in-motion, gradual-heating technique also allows lower energy per pulse than older single-pulse platforms, which is generally more comfortable and better suited to darker skin tones. Which wavelength combination and course length are proposed — and how treatment areas differ in growth-cycle spacing — is confirmed individually rather than assumed in advance.
Match the wavelength to the hair and skin, not the setting to the calendar.
The wavelength combination and spacing used across your course follow from your hair color, skin tone and treatment area — rather than a single default setting applied to every patient.

The Four Settings, Explained
Mode 01
Mode 02
Mode 03
Mode 04
Wavelength-matched settings, planned around an honest treatment course.
Treatment areas commonly need different wavelength combinations and spacing, since hair thickness, growth-cycle length and skin tone can all vary by area. During consultation, the doctor reviews which settings below apply to your case before proposing a course.
755nm — Fine & Fair-Skin Hair
The shorter wavelength most strongly absorbed by melanin, generally favored for fine hair on lighter skin tones.
1064nm — Deeper Skin Tones
A longer wavelength less strongly absorbed by surrounding skin melanin, generally favored for medium-to-deeper skin tones.
Face-Cycle Spacing
Facial hair cycles faster than body hair, so facial areas are generally spaced four to six weeks apart between sessions.
Body-Cycle Spacing
Body areas cycle more slowly, so sessions are generally spaced six to eight weeks apart to catch hairs entering the active phase.
What Laser Hair Removal Addresses
Hair removal concerns, matched to a setting, not treated identically.
The concerns below give a sense of how laser hair removal is planned at LOUAVE. Each case is reviewed individually for hair color, skin tone, treatment area and hair thickness before a wavelength combination is proposed.
Facial Hair (Upper Lip & Chin)
Fine facial hair generally responds well over a staged course, with sessions spaced to match the faster facial growth cycle.
Face-Cycle SpacingUnderarm & Bikini Area
Coarser, denser hair in these areas generally responds well, with skin sensitivity considered when selecting energy settings.
Body-Cycle SpacingLegs & Arms
Larger treatment areas are addressed with the in-motion technique, generally more comfortable across broader surfaces.
Body-Cycle SpacingDeeper Skin Tones
The 1064nm wavelength is generally favored here, reducing pigment-change risk while still targeting hair follicle melanin.
1064nm ModeVery Light Blonde, White or Grey Hair
These hair colors contain little melanin and respond poorly to any laser platform; expectations are discussed honestly before treatment begins.
Limited-Response HairIngrown Hair & Shaving Irritation
Reducing hair regrowth over a course can also reduce the ingrown hair and irritation that frequent shaving or waxing can cause.
Course-Based Reduction Treatment Philosophy
Match the setting deliberately, not the same wavelength for every patient.
Because hair color, skin tone and treatment area all affect how many sessions a course will realistically need, the approach begins with an honest assessment before any wavelength combination is proposed.
Wavelength-Matched Selection
Hair color, hair thickness, skin tone and treatment area are reviewed together before a wavelength combination is proposed, rather than defaulting to one setting.
Hair and skin reviewed before wavelength is chosen
No default or one-size setting
Skin tone reviewed before treatment
Individualised, not formulaic
Preferred focus: wavelength-matched, realistic planning
Conservative Settings Where Skin Tone Calls For It
Because laser hair removal carries a pigment-change risk in tanned or medium-to-deeper skin, settings are reviewed carefully and a staged approach is preferred over aggressive early passes.
Skin tone reviewed to manage pigment risk
Reviewed before further sessions
Response checked between passes
Additional sessions expected for coarse hair
Assessment focus: deliberate, tone-aware treatment
Honest About What Laser Can't Do
Laser disables hair follicles in their active growth phase over a staged course; it does not guarantee permanent removal of every hair. Very light blonde, white or grey hair in particular responds poorly, and this is discussed openly before treatment begins.
Realistic expectations set upfront
Not presented as guaranteed permanent removal
Limited-response hair colors discussed openly
Individual results still vary

LOUAVE Treatment Process
A structured plan built around your hair and skin.
The process below applies across Soprano Titanium's wavelength combinations, from initial assessment through to wavelength selection, sessions and ongoing course planning.
Consultation & Hair Assessment
The doctor examines hair color, thickness, growth pattern, treatment area and skin tone to determine which wavelength combination is actually appropriate.
Hair-first assessmentWavelength & Course Planning
The 755nm/810nm/1064nm combination, energy settings, and an approximate session count and spacing are set for your specific case.
Wavelength-specific planningTreatment Session(s)
The in-motion pass is delivered across the treatment area according to the selected wavelength combination and energy settings.
Wavelength-matched deliveryProgress Review & Course Planning
Hair reduction is reviewed after each session, with further sessions or a setting change planned based on how the area is responding.
Ongoing progress review Results & Development
Day 0
Days 7–14
Weeks 4–8
Ongoing
Hair thins gradually, reviewed session by session.
Each session disables hairs that were in their active growth phase at the time, which shed over the following days to weeks — visible reduction typically builds across several sessions rather than a single pass. How much a course ultimately reduces hair depends on hair color, treatment area and skin tone, and is reviewed against the timeline the doctor sets out at consultation.
Treatment session
The in-motion pass is delivered across the treatment area; mild warmth and redness around treated follicles is common immediately afterward.
Treated hairs shed
Hairs that were disabled during the session typically shed over the following one to two weeks, sometimes appearing as if hair is still growing before it falls out.
Review & next session, if planned
Hair reduction is reviewed at the next visit, timed so newly active hairs can be caught by the following session.
Continued sessions until desired reduction
Most courses need six to eight sessions to reach the desired reduction; occasional touch-up sessions may be needed to maintain results over time.
International patients planning a hair removal course should discuss a realistic schedule, since sessions are typically spaced four to eight weeks apart depending on the treatment area.
Suitability & Screening
Suitability is confirmed through an honest health review.
Treatment may be modified, delayed or declined when certain health factors are present, or when hair color makes a strong response unlikely.
Laser hair removal may be discussed when:
- You have hair with enough pigment to respond to laser — not very light blonde, white or grey.
- You are able to attend a staged course of sessions, often six to eight, spaced four to eight weeks apart by area.
- You understand that permanent reduction, not permanent removal, is the realistic expectation, and touch-ups may be needed.
- Your skin has not had a recent aggressive laser, peel or procedure, or significant sun exposure or tanning, that could increase treatment risk right now.
- You do not have active, untreated skin infection or inflammation over the treatment area.
Tell the doctor before treatment about:
- Pregnancy, planned pregnancy or breastfeeding.
- Current use of isotretinoin, or other photosensitising medication.
- A history of keloid scarring, cold sores, or active skin infection in the treatment area.
- Your natural skin tone and any recent tanning, since laser hair removal carries a pigment-change risk, particularly on tanned or medium-to-deeper skin.
- Any previous laser or electrolysis hair removal in this area, including outcomes and how your skin responded.
Aftercare
Let the area settle, then attend your next session.
Follow the specific instructions provided by the treating doctor after each session, since proper aftercare supports comfort and helps maintain results between sessions.
Shave, Don't Wax, Between Sessions
Shaving keeps the follicle intact for the next session; waxing or plucking removes the root the laser needs to target and should be avoided during a course.
Soothe Mild Redness or Warmth
Mild redness or warmth around treated follicles typically settles within a few hours to a day; cool compresses can help if needed.
Strict Daily Sun Protection
Apply broad-spectrum SPF daily and limit direct sun exposure, both while treating and between sessions, to protect results and reduce pigment-change risk.
Attend the Review Visit
Attend the follow-up review so the doctor can confirm progress and decide whether a further session or a setting change is appropriate.
Safety Information
General information, not a substitute for consultation.
This page provides general educational information about laser hair removal. It does not replace an individual medical consultation, and effects, recovery and the degree of reduction vary between patients and between treatment areas.
Seek prompt attention for:
- Blistering, crusting, or open skin breakdown, beyond the mild redness or warmth expected after treatment.
- Pigment that appears markedly darker or lighter than expected in the weeks after a session, rather than settling on its own.
- Persistent or worsening redness, swelling, or discomfort in the treated area beyond the expected few-hour window.
- Signs of infection, including increasing pain, warmth, discharge or fever at the treated area.
- Any allergic reaction to topical products used as part of the treatment or aftercare, such as significant redness, swelling or itching.
Any sign that the treated area is not settling as expected should be reported to the clinic promptly rather than waiting for the next scheduled review.
Frequently Asked Questions
Questions about laser hair removal.
Hair and skin assessment, session count, expected timelines and realistic outcomes for specific hair colors are confirmed during consultation.
What is Laser Hair Removal?
This page covers general information on laser hair removal using the Soprano Titanium multi-wavelength platform, and how LOUAVE approaches it — including how hair color, skin tone and treatment area affect wavelength and session planning.
What laser platform is used?
LOUAVE uses Soprano Titanium, an in-motion diode platform combining 755nm, 810nm and 1064nm wavelengths. Which combination is used depends on your hair color, skin tone and treatment area.
How does the laser actually reduce hair?
The laser targets melanin in the hair follicle, heating it enough to disable future growth. Only hairs in their active growth phase respond, which is why repeated sessions are needed to catch hairs as they cycle through growth phases.
How many sessions are usually needed?
Treatment is typically delivered as a staged course, often six to eight sessions spaced four to eight weeks apart depending on the area. Facial areas generally need closer spacing than body areas.
Does laser hair removal work on all hair colors?
No. Darker hair with more melanin responds best. Very light blonde, white or grey hair contains little melanin and responds poorly to laser regardless of platform or wavelength.
Does laser hair removal hurt?
Most patients describe a warm, mildly stinging sensation, generally more comfortable than older single-pulse lasers thanks to the in-motion, gradual-heating technique. Numbing is not usually required.
What is the downtime after treatment?
Downtime is typically minimal — mild redness or warmth around treated follicles usually settles within a few hours to a day, and most patients return to normal activities immediately.
Is the hair reduction permanent?
Laser hair removal is generally described as permanent reduction rather than permanent removal. Most patients see significant, lasting reduction after a full course, though occasional touch-up sessions may be needed over time.
Is it safe for darker skin tones?
Soprano Titanium's 1064nm wavelength is generally favored for medium-to-deeper skin tones, since it is less strongly absorbed by surrounding skin melanin, reducing pigment-change risk compared to shorter wavelengths alone.
Should I shave or wax before a session?
Shaving is recommended before each session. Waxing or plucking should be avoided during a course, since these remove the hair root the laser needs to target.

Since a full course often spans six or more sessions weeks apart, the doctor will help set expectations for what's achievable within your trip.
Important treatment information
This page provides general educational information about laser hair removal using the Soprano Titanium multi-wavelength platform, and does not replace an individual medical consultation. Hair color, hair thickness, skin tone and treatment area all affect expected results and recovery; not every hair color responds the same way, and very light blonde, white or grey hair generally does not respond well to any laser platform. Treatment must be planned by an appropriately experienced medical professional after reviewing hair color and growth pattern, skin tone, recent sun exposure or tanning, treatment area, pregnancy or breastfeeding status, previous hair removal treatments, health history, medications, allergies and informed consent. Temporary effects may include redness, warmth, swelling or follicular bumps in the treated area, which typically settle within a few hours to a day of each session. Other possible effects include post-inflammatory hyperpigmentation or hypopigmentation, incomplete reduction requiring further sessions, or, uncommonly, textural change. Rare but serious complications include burns, blistering, infection, unexpected scarring, and allergic reactions to topical products used during treatment or recovery. Seek prompt medical advice for pigment that becomes markedly darker or lighter than expected, blistering or skin breakdown, signs of infection, or symptoms of a significant allergic reaction. Daily sun protection is recommended both during and after a course, and results, session count, degree of reduction, and long-term stability vary by individual and cannot be guaranteed.
