Long-Pulsed Nd:YAG in Korea is a versatile and widely used laser treatment for hair removal, vascular lesions, pigmentation, and skin rejuvenation. Unlike Q-switched Nd:YAG lasers that deliver energy in ultra-short bursts, long-pulsed Nd:YAG lasers release energy in longer pulses, allowing for deeper penetration into the skin. This makes them effective for treating deeper vascular structures, collagen stimulation, and long-term hair reduction.
In Korea, dermatology clinics have adopted long-pulsed Nd:YAG as a multi-purpose treatment. It is often integrated into advanced skincare packages that include Aqua Peel, hydrating facials, or whitening therapies, ensuring safe and comprehensive results for both locals and international visitors.
What It Is
The long-pulsed Nd:YAG laser operates primarily at 1064 nm wavelength, allowing deeper skin penetration compared to other laser systems. Its long pulse duration makes it ideal for targeting larger structures such as hair follicles and deeper blood vessels, while minimizing damage to the surrounding skin.
Key uses include:
- Laser hair removal (safe for darker skin tones).
- Treatment of vascular lesions such as spider veins and hemangiomas.
- Pigmentation control for melasma and freckles.
- Skin tightening and rejuvenation through collagen stimulation.
- Rosacea and redness reduction.
In Korea, this laser is particularly valued for its versatility and safety for Asian skin, which is more prone to pigmentation issues.
Why It’s Done
Patients undergo long-pulsed Nd:YAG treatment in Korea for multiple reasons:
- Medical reasons → To treat spider veins, vascular birthmarks, rosacea, and hemangiomas.
- Cosmetic reasons → For permanent hair reduction, pigmentation control, and skin tightening.
- Preventive reasons → Many Koreans use it as part of maintenance care, preventing premature aging by boosting collagen production.
Because of its deep penetration and minimal surface damage, it has become a trusted option in Korean dermatology clinics.
Alternatives
While long-pulsed Nd:YAG is highly effective, alternatives are available in Korean clinics:
- Q-switched Nd:YAG → For superficial pigmentation and laser toning.
- Pico lasers (PicoWay, PicoSure Pro) → For precise pigmentation and acne scars.
- Alexandrite laser (755 nm) → For lighter skin hair removal and pigmentation.
- Diode laser → Popular for hair removal.
- Vbeam PDL → For redness and vascular lesions.
- IPL/BBL photofacials → For pigmentation and vascular improvement.
- Fractional lasers (Fraxel, Moxi, Clear + Brilliant) → For anti-aging and resurfacing.
Preparation
Preparation in Korea is detailed and patient-oriented:
- Consultation → Dermatologists assess hair type, vascular issues, or pigmentation with imaging tools.
- Pre-care instructions → Avoid sun exposure, tanning, exfoliants, and retinoids before treatment.
- Shaving (for hair removal) → Patients are asked to shave the treatment area 24 hours before.
- Hydration → Using moisturizers and sheet masks ensures optimal skin condition.
- Medical disclosure → Patients should inform doctors about medications, skin sensitivities, or history of keloids.
Numbing cream may be applied depending on the treatment intensity.
How It’s Done
A long-pulsed Nd:YAG session in Korea usually lasts 20–40 minutes, depending on the area:
- Cleansing – Makeup, dirt, and oils are removed.
- Cooling gel – A protective gel may be applied.
- Laser application – The dermatologist delivers long pulses of 1064 nm energy to the targeted area.
- For hair removal: Targets the follicle root.
- For vascular lesions: Collapses blood vessels without harming skin.
- For rejuvenation: Stimulates dermal collagen.
- Cooling – Integrated cooling systems or cold compresses are used.
- Post-care – Soothing cream, hydrating masks, or LED therapy.
- Final step – Sunscreen and moisturizer are applied.
The sensation is often described as a warm snapping or stinging but is well-tolerated.
Recovery
Recovery varies depending on the application:
- Hair removal → Mild redness or bumps around follicles that resolve within hours.
- Vascular treatments → Redness or slight bruising for 1–3 days.
- Pigmentation and rejuvenation → Temporary redness or dryness, fading within a day.
Korean clinics often enhance recovery with hydration facials, soothing serums, and calming sheet masks. Patients are instructed to use SPF 50+ sunscreen daily and avoid hot saunas or intense workouts for 24 hours.
Complications
Long-pulsed Nd:YAG is safe, but mild side effects can occur:
- Temporary redness or swelling.
- Slight bruising for vascular treatments.
- Follicular irritation after hair removal.
- Rare risks of pigmentation changes if aftercare is neglected.
Korean dermatologists reduce risks by tailoring pulse duration and fluence to each patient’s skin type and providing detailed aftercare protocols.
Treatment Options
In Korea, long-pulsed Nd:YAG is offered in specialized programs:
- Hair removal packages → Especially for darker skin types and large areas (legs, arms, back).
- Vascular treatment programs → For spider veins, rosacea, and vascular birthmarks.
- Pigmentation programs → Combining Nd:YAG with whitening serums.
- Anti-aging packages → Nd:YAG with collagen-boosting facials and Vitamin C infusion.
- Combination treatments → Nd:YAG plus Aqua Peel, Hydrafacial, or Shurink HIFU.
Seoul clinics, particularly in Gangnam, frequently offer multi-session deals (3–6 sessions), making this treatment both accessible and affordable for locals and medical tourists.
