Melasma (chloasma) is an acquired pigmentary disorder commonly affecting women, presenting as symmetrical brown patches on the malar region, forehead, upper lip, and mandible — irregularly bordered but well-demarcated. Among all pigmentary conditions, melasma is the most notoriously stubborn and relapse-prone. Unlike freckles or solar lentigines, melasma is chronic, recurrent, and multifactorial — hormonal fluctuations, UV exposure, thermal stimulation, inappropriate skincare, and genetic predisposition can all trigger or worsen it. Many have cycled through laser sessions, depigmenting creams, and oral whitening supplements, only to watch melasma resurge. Rappoel Dermatology near Gangnam Station, Seoul, employs a three-step combined protocol — Pico Laser + IPL + Tranexamic Acid — simultaneously targeting pigment at the cutaneous level and pathogenic mechanisms at the molecular level.
Why Is Melasma So Stubborn? — Four Core Mechanisms
- Hyperactive melanocytes: Melasma-affected melanocytes may not be more numerous, but individual cell activity is 3-5x higher than in normal skin — exquisitely sensitive to stimuli (UV, heat, friction)
- Damaged basement membrane: UV disrupts the epidermal-dermal junction, allowing melanin granules to drop into the dermis (pigmentary incontinence), forming deeper pigment particles that are slower to clear
- Abnormal vascular proliferation: Melasma zones show increased micro-vessel density and permeability (VEGF overexpression); these abnormal vessels continuously release melanogenic stimulators like endothelin, creating a vicious vascular-pigment cycle
- Photoaging and chronic inflammation: Long-term UV-induced low-grade inflammation activates mast cells to release histamine, further stimulating melanogenesis
Rappoel’s Three-Step Melasma Treatment System
- Step 1 — Pico Laser: Picosecond (one-trillionth of a second) ultra-short pulses generate photoacoustic shockwaves within melanin particles, shattering pigment into fragments 10x smaller than those from traditional nanosecond lasers — more readily engulfed by macrophages. Pico laser’s thermal damage is extremely low, making it particularly safe for melasma (a condition known to worsen with heat). 755nm picosecond or 1064nm fractional mode, every 3-4 weeks, 3-5 sessions per course
- Step 2 — IPL (Intense Pulsed Light): Broad-spectrum light selectively targets melanin in the epidermis/superficial dermis and abnormal vasculature. IPL uniquely addresses melasma’s vascular component — by closing these abnormal ‘vascular supply lines,’ the continuous release of melanogenic stimulators is interrupted. Once monthly, staggered 1-2 weeks apart from pico laser sessions
- Step 3 — Tranexamic Acid (oral or topical): Tranexamic acid blocks UV-induced melanogenesis by inhibiting plasmin activity, and is the established standard oral treatment for melasma. Rappoel protocol: low-dose oral tranexamic acid 250mg twice daily for 8-12 weeks, or 2% topical tranexamic acid serum
- Foundation — Rigorous sun protection: Melasma patients must use SPF50+ PA++++ broad-spectrum sunscreen, applied generously and reapplied. Physical (mineral) sunscreens (titanium dioxide, zinc oxide) are more melasma-friendly than chemical sunscreens — they reflect and scatter UV without generating heat, avoiding thermal melanocyte activation
- Adjunct — Intradermal tranexamic acid mesotherapy: For severe or refractory melasma, Rappoel offers localized tranexamic acid micro-injections, delivering medication directly to the pigment-active zone for higher local concentration with reduced systemic side effects
Rappoel Melasma Treatment Protocol
- Initial assessment (30 min): Wood’s lamp and polarized dermoscopy to classify melasma type (epidermal/dermal/mixed), assess vascular proliferation, screen for coexisting freckles or lentigines
- Customized protocol design: Epidermal-dominant → pico laser primary; dermal-dominant → pico laser + IPL + oral tranexamic acid triple combination; mixed → treatment weighting adjusted by epidermal/dermal ratio
- Session 1 treatment (40 min): Cleanse → topical anesthesia → pico laser full-face or focal treatment → ice cooling → repair serum and sunscreen application
- Staggered session (3-4 weeks later): IPL treatment → focused on malar zone abnormal vasculature
- Long-term maintenance (every 3-6 months): Low-energy pico or IPL maintenance after plateau, with year-round sun protection and tyrosinase-inhibiting skincare
Rappoel Dermatology emphasizes: melasma is a chronic condition requiring a ‘treatment + maintenance’ long-term management mindset — not a fantasy of ‘one-time cure.’ A reasonable expectation is 70-90% lightening with stable control and minimized recurrence. Located a 3-minute walk from Gangnam Station Exit 10, with English and Chinese consultation throughout.
Frequently Asked Questions
Will laser treatment make melasma darker? (Post-inflammatory hyperpigmentation)
This is a common fear, but modern picosecond laser technology has largely eliminated this risk. Traditional nanosecond lasers, with longer pulse duration and greater thermal effect, did carry a real risk of post-inflammatory hyperpigmentation (PIH) in melasma treatment. Picosecond lasers reduce pulse width to the picosecond range (1/1000 of a nanosecond), cutting thermal effect to less than 1/10 of nanosecond lasers — PIH probability drops significantly. However, prerequisites remain: conservative energy settings, strict post-treatment sun protection, and concurrent tranexamic acid to suppress melanocyte activity. Rappoel starts melasma laser energy low and gradually titrates upward based on skin response and safety window — never aiming for immediate dramatic results at the cost of safety.
Why do so many people say melasma can’t be cured?
Because melasma’s essence is a complex disease of chronic inflammation + vascular abnormality + hormonal sensitivity — not simply ‘too much pigment.’ Three common failure points: (1) doing laser without sun protection — UV continuously activating melanocytes is like pouring gasoline while trying to put out a fire; (2) solo treatment — using only one modality while ignoring the vascular-pigment vicious cycle; leaving abnormal vessels intact is like keeping the power supply to the pigment factory; (3) chasing 100% clearance — stopping maintenance as soon as visible fading occurs; melanocyte activity rebounds. Correct strategy: combined treatment + long-term maintenance + reasonable expectations (70-90% lightening = success).
How many pico laser sessions to see melasma improvement?
Epidermal melasma responds fastest — 30-50% lightening visible after the 1st-2nd pico session (patch lightening, size reduction). Dermal and mixed types require 3-5 combined treatment sessions (pico + IPL + tranexamic acid) for 50-70% lightening. Reaching the ideal plateau (70-90% lightening) typically takes 6-9 months of systematic treatment and maintenance. Individual melanocyte ‘activity level’ varies — younger individuals without pregnancy history and with good sun protection habits respond faster; perimenopausal women or those with oral contraceptive history need more time.
What lifestyle adjustments are needed during melasma treatment?
Every detail of daily life can affect melasma: (1) Sun protection is non-negotiable — apply sunscreen even indoors (UVA penetrates glass), in cars, and near windows; (2) Avoid thermal stimulation — saunas, hot yoga, electric blankets, and cooking heat all activate melanocytes via the heat shock protein pathway; (3) Discontinue irritating skincare — products with retinoids or high-concentration AHAs damage the epidermal barrier and worsen inflammation; (4) Manage stress and sleep — elevated cortisol indirectly stimulates melanogenesis; (5) Blue light protection — phone and computer blue light can worsen pigmentation; consider iron-oxide-containing makeup or blue-light sunscreen. Each of these points is critical for melasma patients.
How is Rappoel’s melasma treatment different from other clinics?
Four core differentiators: (1) Classified diagnosis and treatment — Wood’s lamp and polarized dermoscopy for precise typing; epidermal and dermal types receive completely different protocols, no one-size-fits-all; (2) Three-step system — pico laser removes pigment + IPL closes vessels + tranexamic acid blocks signaling pathways, simultaneously targeting melanin production (upstream), transport (midstream), and deposition (downstream); (3) Conservative energy strategy — melasma treatment prioritizes safety over speed: low starting energy, gradual escalation; (4) Long-term management philosophy — not a one-off transaction; from the first session, we co-develop a 6-12 month long-term expectation and management plan with each client.
