Pigmentation is the most-treated complaint in Korean dermatology after acne. Pico-second lasers — devices that fire ultra-short pulses to fragment pigment with minimal thermal damage — have become the standard tool. Three platforms dominate Gangnam clinics: Cynosure\'s PicoSure Pro, Syneron Candela\'s PicoWay Resolve, and Lutronic\'s domestically produced PICO4Plus.
What pico lasers do (and don\'t)
Pico lasers shatter pigment into smaller particles that the body clears via the lymphatic system. Compared with older Q-switched lasers:
- Shorter pulse duration (300–450 picoseconds vs. nanoseconds).
- Less thermal damage to surrounding tissue.
- Lower risk of post-inflammatory hyperpigmentation (PIH), a real consideration in Asian skin.
- Faster pigment clearance per session.
What they don\'t do: turn dark skin lighter, prevent future pigmentation, or replace daily sun protection. Pico is the correction tool; sunscreen and skincare are the maintenance tools.
The three platforms
PicoSure Pro (Cynosure)
- 755 nm primary wavelength with 532 nm and 1064 nm options.
- Strong reputation for tone correction and overall brightness.
- Premium pricing.
PicoWay Resolve (Syneron Candela)
- Multi-wavelength platform with 532, 785, and 1064 nm options.
- Excellent versatility — handles pigmentation, melasma, tattoo removal, and acne scars.
- Strong real-world record for melasma in Korean dermatology.
Lutronic PICO4Plus
- Korean-made platform with four wavelengths.
- Strong adoption across Gangnam clinics on a value basis.
- Solid performance on Asian skin pigmentation indications.
Practical reality: in a skilled operator\'s hands, all three platforms produce strong pigmentation outcomes. The clinic\'s technique tuning matters more than the brand for typical pigmentation indications.
Indications by pigmentation type
Sun spots / lentigines
Best response of any pigmentation type. Typical course: 2–4 sessions, spaced 4 weeks apart. Many lesions clear after 1–2 sessions.
Melasma
The hardest pigmentation to treat. Pico lasers are part of a multi-modal protocol that typically includes:
- Low-fluence pico toning (gentle settings).
- Topical agents — tranexamic acid, kojic acid, niacinamide, hydroquinone where appropriate.
- Strict sun protection (broad-spectrum SPF 50+, daily, year-round).
- Sometimes oral tranexamic acid in carefully selected patients.
- 6–10 sessions over 3–6 months, with maintenance.
Melasma can recur. Treatment improves it; cure is not realistic. Patients who do not maintain sun protection see consistent rebound.
Post-inflammatory hyperpigmentation (PIH)
Pigmentation left behind after acne or inflammation. Often resolves with conservative pico toning plus topicals.
Freckles and ephelides
Excellent response, often 1–3 sessions. Recurrence with sun exposure is common.
Tattoo removal
Pico lasers are now the standard for tattoo removal — black ink responds best, certain colored inks remain challenging.
What "pico toning" means in Korea
"Pico toning" describes very-low-fluence, full-face pico passes used for general tone evenness, mild melasma, pore size, and a luminous "glass skin" effect. Many Gangnam dermatology clinics offer pico toning as a monthly maintenance service.
- Not for active deep pigmentation alone — best as a maintenance and tone-evening modality.
- Typical session: 15–25 minutes, no downtime.
- Pricing is the most accessible of any pico service.
Cost ranges in Gangnam (2026, USD)
- Pico toning full face: $100–$280 per session.
- Spot pico for individual lentigines: $80–$200 per session.
- Melasma protocol per session: $200–$450.
- Tattoo removal: priced by tattoo size and complexity.
- Multi-session packages (5–8 sessions): typically discounted 10–25%.
What to ask in consultation
- Which pigmentation type is dominant in my case, and which protocol addresses it?
- What device and wavelength will be used, and at what fluence?
- What topical and lifestyle adjuncts are part of the protocol?
- What rebound rate do you see for melasma, and what is the maintenance plan?
Risks to take seriously
- PIH — particularly in darker skin types, careless settings can produce more pigment than they remove.
- Hypopigmentation — over-aggressive tattoo removal or melasma settings can produce permanent light patches.
- Rebound melasma — without protocol adherence, pigmentation often returns within months.
Choose a clinic experienced with your skin type, and follow the protocol. Pico lasers are powerful tools that reward operator skill and patient adherence in equal measure.
