Laser Hair Removal

How it works

The laser emits light absorbed by melanin, the pigment in hair. The energy heats the follicle enough to reduce its ability to grow hair. Because hair grows in cycles, only follicles in the active phase respond, which is why several sessions spaced weeks apart are needed. Most people see a reduction in hair density and thickness, but regrowth of some fine hairs can occur, and results vary by person, body area, hormones, and hair color. Light, gray, or red hair often responds poorly.

Who it may suit

• Dark, coarse hair on lighter to medium skin tones, though modern devices can serve a wider range
• Areas such as underarms, legs, bikini line, or upper lip where long-term reduction is wanted
• People tired of repeated shaving or waxing, and with ingrown hair tendencies
• Patients who can commit to a series of sessions over months

The treatment day

1. Skin and hair assessment. Skin tone, tan, hair color, and medications are reviewed, and a patch test may be done.
2. Preparation. The area is shaved, cleaned, and protected with eye shields, and cooling is arranged.
3. Laser pulses. The handpiece is moved across the area. Many people feel a snapping or hot pricking sensation.
4. Cooling and plan. The skin is soothed and the interval to the next session is set.

Aftercare

• Avoid sun exposure and tanning before and after sessions, and use sunscreen
• Skip waxing and plucking between visits, since the laser targets the hair root
• Avoid hot baths, saunas, and heavy exercise for a day if advised
• Use a gentle moisturizer, and report blistering or darkening to the clinic

Things to know first

• Redness, swelling around follicles, and temporary tenderness are common
• Burns, blisters, and darkening or lightening of skin can occur, especially with tanned or deeper skin tones and an incorrectly chosen laser
• Paradoxical hair growth is a rare effect in which fine hair increases in a treated area
• Photosensitizing medications, active skin infection, and pregnancy affect suitability
• It is not effective on white, gray, or very light hair, and total removal should not be expected

What to check before booking laser hair removal in Gangnam

The central question is whether the laser suits your skin. Ask which wavelength is used and whether more than one device is available. Some wavelengths are safer for deeper skin tones, and a clinic that can explain why one fits you has probably thought about it. If the same settings are applied to everyone regardless of tone, treat that as a warning.

Ask who performs the session and who can respond if you are burned. Many clinics delegate pulses to trained staff under a physician, which can be acceptable when the process is supervised and the first assessment is thorough. You can ask to see the device's model, how the cooling works, and how sessions are recorded.

Think about the package structure. Because this is a long series, a large prepaid commitment carries risk if the clinic changes its terms or your skin reacts. A fair arrangement allows a test area, a review after the first sessions, and clear refund conditions in writing. Also confirm what happens to your plan if you need to pause for sun exposure or travel.
