The Complete Laser Hair Removal Guide — How to Plan It as a Visitor to Korea

Who it suits / who it doesn't

Laser hair removal sends light to the hair root (follicle) to weaken its ability to regrow. Because it greatly reduces the need to shave or wax again and again, it is popular with both women and men.

• People tired of shaving daily or waxing often
• People whose skin gets red after shaving or who get ingrown hairs
• People bothered by underarm, upper lip or leg hair
• Men with dark, heavy beards who are left with a bluish shadow after shaving

How it works — why one session isn't enough

Laser light is absorbed by the dark pigment (melanin) in the hair and turns into heat, which damages the follicle that produces the hair. That's why the darker and thicker the hair, and the lighter the surrounding skin, the better the response.

The hair growth cycle

• Growth phase (anagen): the hair is firmly attached to the follicle and growing. Laser works on hair in this phase.
• Regression phase (catagen): the hair separates from the follicle. Response to laser is weak.
• Resting phase (telogen): the follicle is resting. Hair at this stage will come back in the next growth phase.

The hairs in one area are not all in the same phase, and only some are in the growth phase at any given time. That's why treatment has to be repeated each time resting hairs grow back in, which is the reason you need multiple sessions at set intervals.

Features and session estimates by area

Hair thickness and growth cycles differ by area, so the number of sessions and spacing differ too. The figures below are general ranges; your actual number depends on hair amount, thickness and skin tone.

Device types — depends on your skin tone

Hair removal lasers behave differently depending on wavelength. No single one is simply the best; what matters is choosing by skin tone and hair condition, and many devices combine several wavelengths.

• Gentlemax, Clarity, Soprano, LightSheer and so on are all names of hair removal devices.
• If your skin is on the darker side and a wavelength with strong melanin absorption is used at high power, the risk of burns and pigment changes goes up. If you have deeper skin tones, such as people from Southeast or South Asia, be sure to check that a suitable device such as Nd:YAG is available.
• More important than the device name is that the wavelength and power are chosen after looking at your skin and hair.

Treatment day, step by step

1. 1
   Check-in and consultation (about 15–20 minutes): we check your skin tone, hair thickness, recent sun exposure and medications, then decide on the area and device. Your manager interprets.
2. 2
   Shaving checkit's best to shave the treatment area beforehand. Any remaining hair is trimmed at the clinic.
3. 3
   Numbing cream (about 20–30 minutes, if needed): for more painful areas such as the beard and bikini, numbing cream may be applied.
4. 4
   Laser treatment (5–40 minutes)done while a cooling device chills the skin. Underarms take a few minutes; full legs take 30 minutes or more.
5. 5
   Soothing (about 10 minutes)redness is calmed with soothing gel or cooling before you head home. You can go sightseeing right away.

How should visitors plan? Three approaches

Laser hair removal isn't finished in one visit. People coming from abroad often choose whichever of the three approaches below suits them.

Option 1 — Match your return trips to Korea

• Suits people who come to Korea every 4–8 weeks (business trips, frequent travel).
• Tell us your visit dates in advance and we'll book each next session to fit the spacing for each area.
• A slightly longer gap is fine, but pulling sessions closer together than recommended has little point.

Option 2 — Try one session on this trip

• You can experience for yourself how your skin and hair respond and how the pain feels.
• Please go in knowing that one session only sheds some hair, and a long-term reduction is hard to expect from a single session.

Option 3 — Start in Korea and continue near home

• Have the first session in Korea together with an assessment, then continue at a clinic where you live.
• If you ask the clinic to record the device name, wavelength, power and your skin reaction, it's easier for your local clinic to pick up from there.
• It's a good idea to check beforehand whether a similar type of device is available where you live.

What recovery looks like, day by day

• Same day
  Redness and a burning feeling, and slight swelling like small bumps around the pores, may appear. Most of it settles within a few hours.
• 1–2 days
  Any remaining redness fades. Wait until irritation has settled before using makeup or deodorant.
• 1–3 weeks
  Hair may look like it's growing, then comes out easily. Don't pull it out; let it fall out naturally.
• 4–8 weeks
  Resting hairs grow back in. This is when it's time for your next session.

Pain and cooling

You'll feel a stinging, rubber-band-snap sensation and a momentary heat. It stings more in areas with thick, dense hair (beard, bikini, underarms), and pain tends to lessen as sessions go on and hair thins.

• Most devices have a cooling function (contact cooling, cold air spray and so on) that chills the skin during treatment.
• If you're worried about pain, you can ask for numbing cream.
• Around your period you may be more sensitive to pain. If possible, schedule around it.

Before and after: preparation and aftercare

Before

• Shave 1–2 days before. Do not pluck, wax or use hair removal cream, because that removes the hair roots the laser aims at.
• It's best not to pluck or wax for 4 weeks before.
• Avoid strong sun and tanning from 2 weeks before. Tanned skin raises the risk of burns and the treatment may be postponed.
• On the day, come without deodorant, perfume or lotion on the treatment area.
• Tell us about all the medication you take at your consultation.

After

• Apply sunscreen and keep the treated area out of direct sunlight. This is the most important habit for preventing pigmentation.
• On the day, avoid saunas, jjimjilbang, hot baths, intense exercise and alcohol.
• For 1–2 days, don't use exfoliants, scrubs or strongly scented products.
• Until your next session, manage hair by shaving only.
• It's best to put off beach or pool plans for a few days after treatment.

Normal reactions and symptoms that need immediate contact

Reactions that can normally occur

• Redness, burning and mild swelling right after treatment (a few hours to 1–2 days)
• Small bumps rising around the pores
• Mild itching

Rare side effects that can occur

• Folliculitis: acne-like inflammation in the hair pores. Most cases settle with care.
• Burns / blisters: can occur when the skin is dark or tanned, or when the power isn't suitable.
• Pigment changes: the skin may temporarily darken or lighten. Most recover over time, but some last longer.
• In rare cases, fine hair around the treated area has been reported to become thicker instead (on the face, neck and so on).

Contact your manager right away if

• Blisters form or the skin weeps fluid
• Redness or pain keeps getting worse after a day
• Pus collects or heat spreads in the treated area
• The skin color has changed noticeably

Good questions to ask at your consultation

1. Which device (wavelength) will you use for my skin tone and hair?
2. How many sessions and what spacing does this area usually need?
3. What can I expect if I only have it done once this time?
4. Can you record the device and settings so I can continue back home?
5. How do you manage pain (numbing cream, cooling)?
6. If I have a side effect, how do I contact you after I go home?

How to choose a clinic

• Does the doctor personally look at your skin tone and hair condition and decide the device and power?
• Do they tell you the device name, and do they also have a device suited to deeper skin tones?
• Do they avoid promising results like "permanent hair removal in one go" and honestly explain the number of sessions needed?
• Do they offer cooling during treatment and soothing care afterward?
• Is foreign-language service available, and do they check your progress by photo after you return home?

KBEAU connects you with partner dermatology clinics in Gangnam and Apgujeong. Tell us the areas you want and your travel dates, and we'll guide you in advance through a plan that fits your schedule (return visits, one trial session, or continuing near home), and a dedicated manager accompanies you and interprets on the day of treatment.
