Facial spots are among the most common skin concerns for Asian women — they age the face, dull the complexion, and force heavy concealer use. Common spot types include: (1) Sunspots/age spots — pigment accumulation from long-term sun exposure, mostly on cheeks, cheekbones, and the backs of hands, with clear edges and even color. (2) Freckles — hereditary plus sun-triggered, mostly across the nose bridge and cheeks in dotted patterns, appearing from childhood. (3) Melasma — hormone- and sun-related, mostly on cheekbones and forehead, patchy with blurred borders and symmetrical distribution — the ‘most stubborn’ spot. (4) Post-inflammatory hyperpigmentation (PIH) — pigment marks left by acne, trauma, or laser. (5) Nevus of Ota — bluish-gray dermal patches. Pico laser uses picosecond (10 to the power of negative 12 seconds) ultra-short pulses to shatter pigment — the photoacoustic effect breaks pigment granules into much finer fragments that the body metabolizes — compared with traditional nanosecond lasers, pigment clears more thoroughly with less thermal damage to surrounding skin and lower hyperpigmentation risk. Rappoel Dermatology near Gangnam Station, Seoul, provides pico laser pigment treatment.
Technical Principles of Pico Laser Pigment Removal
- Picosecond ultra-short pulses: 1 picosecond = 10 to the power of negative 12 seconds — laser energy releases in an extremely short time, producing a ‘photoacoustic effect’ — pigment granules shatter into ultra-fine fragments (finer than nanosecond lasers) that the body clears more easily
- Photoacoustic over photothermal: Traditional nanosecond lasers ‘heat and burn’ pigment with higher collateral thermal damage; pico lasers primarily ‘shatter,’ with minimal thermal injury — significantly lowering PIH risk
- Selective photothermal/photomechanical destruction: Laser wavelengths (532nm, 755nm, 1064nm) match different pigment colors and depths — short wavelengths for epidermal spots, long wavelengths for dermal spots — precisely targeting the intended pigment
- Focus lens: Some pico systems (e.g., PicoSure) include a focus lens — beyond spot removal, it induces ‘laser-induced optical breakdown (LIOB)’ stimulating collagen renewal — improving pores, fine lines, and texture in one device
- Cumulative sessions: Pigment metabolism takes time — epidermal spots usually need 1-3 sessions, while melasma and dermal nevi need more (4-8+); sessions 3-4 weeks apart let the body gradually clear pigment
Treatment Strategies by Spot Type
- Sunspots/age spots (epidermal): Brown spots with clear edges. Strategy: short-wavelength (532nm/755nm) pico — visible lightening in 1-3 sessions, some with crusting and shedding
- Freckles (epidermal): Dotted spots on the nose bridge and cheeks. Strategy: short-wavelength pico plus whole-face brightening — most fade substantially in 1-2 sessions; freckles are sun- and heredity-related, so strict sun protection is needed to prevent recurrence
- Melasma (mixed, most stubborn): Symmetrical patches on cheekbones and forehead. Strategy: low-fluence pico (avoid overstimulation and PIH) plus oral/topical brightening plus sun protection — a ‘cocktail approach’ requiring patience, multiple sessions, and long-term management
- PIH (acne marks): Pigment left by acne. Strategy: low-fluence pico plus treating the acne source plus repair skincare — mostly improving in 3-5 sessions
- Nevus of Ota (dermal): Bluish-gray dermal patches. Strategy: long-wavelength (1064nm) pico penetrating the dermis — requires many sessions (6-10+), with gradual results
Rappoel Pico Laser Pigment Removal Protocol
- Consultation and spot diagnosis (5 min): Analyze spot type, depth, and pigment distribution with a skin analyzer (VISIA etc.) → confirm classification (epidermal/dermal/mixed) → discuss expectations and course plan → take baseline photos
- Cleansing and preparation (10 min): Makeup removal → select wavelength and energy parameters by spot type → put on protective eyewear
- Pico laser treatment (10-20 min): Fire laser over spot areas one by one → epidermal spots may show mild crusting → whole-face scan evens the complexion → a rubber-band snapping sensation throughout
- Soothing (10 min): Ice pack or calming mask reduces heat and redness → apply repair ointment and sunscreen
- Post-care and follow-up (5 min): Do not pick crusts → boost sun protection for 1 week (physical sunscreen preferred) → moisturize and repair → follow up in 3-4 weeks for the next session
A pico laser session takes about 15-30 minutes (excluding anesthesia); redness fades within hours to 1-2 days (crusting type sheds in 5-7 days); after a full course (3-8 sessions by spot type), spots visibly lighten with an even, bright complexion.

Frequently Asked Questions
What is the difference between pico laser and traditional skin-rejuvenation (ND:YAG) laser? Why is it better?
Core differences: (1) Pulse duration — traditional rejuvenation lasers are ‘nanosecond’ (10 to the power of negative 9 seconds); pico lasers are ‘picosecond’ (10 to the power of negative 12 seconds) — 1,000 times faster. (2) Mechanism — nanosecond lasers use photothermal effects to heat and burn pigment (with collateral thermal damage and higher PIH risk); pico lasers use photoacoustic effects to shatter pigment into finer fragments (minimal thermal injury and lower PIH risk). (3) Clearing efficiency — pico fragments are finer and easier for the body to metabolize — most spots need fewer sessions than with nanosecond lasers. (4) Added skin benefits — pico with a focus lens stimulates collagen renewal, improving pores and fine lines simultaneously (nanosecond lasers do this more weakly). (5) Recovery — pico redness resolves faster with thinner, less crusting. (6) Price — pico costs more per session, but total sessions may be fewer — evaluate by ‘total cost and outcome’ rather than unit price. (7) Rappoel recommends the best laser system by spot type and skin condition — not ‘the more expensive the better’ but ‘the right tool for the diagnosis.’
Is pico laser spot removal safe? Will it cause reactive hyperpigmentation (PIH)?
Safety and PIH explained: (1) Safety — pico laser is an FDA/KFDA-approved mature technology that precisely targets pigment with minimal harm to normal skin; physician operation with energy adjusted to skin tone is the safety key. (2) PIH causes — laser thermal injury overstimulating melanocytes, or insufficient post-treatment sun protection and skin inflammation — darker Asian skin carries higher PIH risk than Caucasian skin. (3) Pico’s advantage — the photoacoustic effect causes minimal thermal injury, significantly lowering PIH risk versus nanosecond lasers (though never zero). (4) Rappoel’s PIH-reduction measures — conservative energy settings by skin tone and spot type (multiple gentler sessions rather than one heavy pass) → pre- and post-brightening skincare → strict sun protection education → low-fluence multi-session strategy for high-risk conditions like melasma. (5) If PIH occurs — most fades within 3-6 months with brightening care and sun protection. (6) Other side effects — redness (hours to 2 days), crusting (sheds in 5-7 days), and very rarely blisters or pigment loss (from excessive energy or particular constitutions) — experienced physicians avoid these. (7) Choosing a provider — treatment must be by a physician, not a beautician, using authentic certified devices.
Does pico laser spot treatment hurt? Is anesthesia needed?
Pain experience: (1) Sensation — most describe a ‘rubber-band snapping’ feel — each pulse brings a brief sting and heat; higher fluence feels stronger. (2) Anesthesia — most spot treatments need none or only topical cream (15-20 minutes); high-fluence or large-area treatment pairs anesthesia with the machine’s contact-cooling handpiece. (3) Zone differences — cheekbones, forehead, and lip area are more sensitive; cheeks tolerate more. (4) After — skin feels hot and flushed (sunburn sensation), easing within hours after icing; crusted areas itch mildly (a normal healing sign — do not pick). (5) Overall — pico laser pain ranks medium among aesthetic lasers; most complete it with no anesthesia or just topical cream. (6) Rappoel prioritizes comfort — adjusting energy pace and anesthesia options by individual tolerance for the smoothest possible treatment.
How many pico sessions do I need? How often?
Session count explained: (1) By spot type — epidermal spots (sunspots, freckles): clear lightening in 1-3 sessions; PIH (acne marks): 3-5 sessions; melasma: multiple low-fluence sessions (4-8+) plus long-term management; dermal nevus of Ota: 6-10+ sessions with gradual results. (2) Intervals — mostly every 3-4 weeks, giving the body time to metabolize pigment fragments and complete skin repair. (3) Why multiple sessions — pigment sits at different depths (epidermis/dermo-epidermal junction/dermis), and metabolism takes time — ‘one heavy pass’ actually raises PIH risk, so cumulative sessions are the safe, effective strategy. (4) Result timeline — lightening visible 2-4 weeks after each session; after a full course, spots clearly fade with even skin tone. (5) Maintenance and recurrence — spots correlate closely with sun and hormones — strict sun protection and regular maintenance are needed after the course; freckles and melasma may recur. (6) Rappoel plans the full course and expected results by spot type at the first consultation, so you know exactly how many sessions and how long it will take.
How much does pico laser spot removal cost? Why do prices vary so much?
Cost explained: (1) Pricing — by treatment area (full face/local) and pulse count; some clinics quote by spot size. (2) Why prices vary — (a) different device brands (PicoSure, PicoWay, Discovery Pico, etc., each with distinct characteristics); (b) fluence and pulse count (treatment depth and scope); (c) physician experience and clinic quality; (d) whether whole-face brightening scans or additional wavelengths are included. (3) Price range — full-face pico varies widely in Korea by package and promotion; Rappoel offers reasonable transparent pricing quoted after consultation. (4) Course total — spot treatment usually needs multiple sessions (3-8), and most clinics offer course packages — evaluate by ‘full course total cost’ rather than per-session price. (5) Value comparison — versus years of concealer and brightening products, or high-priced gentle lasers with limited results — precise targeted treatment is more efficient long term. (6) Rappoel’s principle — no pushing of unnecessary pulses or sessions; planning by spot type and skin condition; for detailed pricing, book a free consultation.
Who is suitable for pico laser spot removal? Who is not?
Suitable: (1) those with epidermal spots like sunspots, freckles, and age spots; (2) those with PIH from acne or trauma; (3) those with melasma wanting improvement (requires cocktail therapy and patience); (4) those with uneven, dull complexions wanting overall brightening; (5) those with dermal pigment such as nevus of Ota wanting gradual lightening (multiple sessions); (6) those wanting to improve pores, fine lines, and spots together (with a focus lens). Unsuitable or cautious: (1) pregnancy and breastfeeding (postpone); (2) active infection or skin disease in the area (treat first); (3) photosensitive diseases (e.g., lupus) or photosensitizing medication use; (4) excessive recent sun exposure or acid peels within 2-4 weeks (needs interval); (5) unrealistic expectations (e.g., expecting melasma gone in one session) — the need for multiple sessions and long-term management must be understood first; (6) anticoagulant use (increased bruising risk — evaluation needed); (7) keloid-prone constitutions (crust healing needs caution).
How long is the recovery after pico laser? Will it crust? Can I wear makeup immediately?
Recovery timeline: (1) At treatment — skin flushes and feels hot (sunburn sensation), easing after icing; most return home the same day. (2) Days 1-2 — the peak redness window; epidermal treatment zones may show thin crusts or pinpoint bleeding (at higher fluence) — no makeup that day; light mineral sunscreen or light makeup from day 2. (3) Days 3-5 — redness fades and crusts start drying and shedding — ‘looking dirty’ is a normal process; never pick (causes scarring or uneven pigment). (4) Days 5-7 — crusts fully shed to reveal fresh pink skin (sun protection is most critical now). (5) Weeks 2-4 — pigment metabolism continues; spots visibly lighten and skin tone gradually evens and brightens. (6) Makeup timing — non-crusted areas accept makeup the next day; crusted areas after shedding. (7) Care notes — avoid saunas, swimming, and strenuous exercise (sweat irritates) for 1 week; avoid exfoliation and acid products; strict sun protection (sunscreen plus hat/umbrella physical protection preferred). (8) Whole-face brightening (low-fluence, no crusting) recovers even faster with almost no time off.
Can pico laser be combined with other treatments?
Combination strategies: (1) Pico plus Rejuran/skin booster — the laser first shatters pigment and stimulates collagen; PN or HA then accelerates repair and adds hydration and glow — a ‘destroy then repair’ golden cycle, with injection treatments 2-4 weeks after laser. (2) Pico plus brightening IV — brightening drips (glutathione, vitamin C) after laser inhibit melanin internally and accelerate fading — attacking from inside and outside. (3) Pico plus low-fluence ND:YAG (melasma cocktail) — melasma treatment often alternates different lasers (low-fluence pico plus low-fluence rejuvenation) to avoid overstimulation by any single modality — combined with oral and topical brightening. (4) Pico plus botox — dynamic lines like forehead and frown lines and spots handled together for whole-face rejuvenation. (5) Pico plus Thermage/ultrasound — lifting devices improve laxity while pico improves pigment and pores — comprehensive handling of aging and pigmentation. (6) Sequencing — device and injection treatments should be spaced 1-2+ weeks apart as the physician plans to avoid overstimulation; Rappoel provides personalized whole-face management programs.
Will spot treatment make things worse? Will spots recur?
The ‘worsening and recurrence’ concern: (1) Cases where treatment worsens things — mostly from excessive fluence (PIH, pigment loss), insufficient post-treatment sun protection, or crust picking — largely avoidable with an experienced physician and correct aftercare. (2) PIH is not permanent worsening — it is temporary post-inflammatory pigmentation that fades within 3-6 months with brightening care and sun protection. (3) Recurrence risk varies by spot type — freckles relate to sun and heredity: strict sun protection greatly delays recurrence but cannot guarantee eradication; melasma relates to hormones and sun: it needs long-term management (sun protection plus skincare plus regular low-fluence maintenance); removed sunspots rarely recur in place with proper sun protection. (4) ‘Not fully cleared’ cases — deep or mixed spots (melasma, nevus of Ota) need many sessions and patience — not that the laser is ineffective but that accumulation is needed. (5) Rappoel’s commitment — full diagnosis and honest communication before treatment (spot type, expected sessions, recurrence possibility) → precise fluence settings → post-treatment follow-up and care guidance — serving with a ‘long-term skin management’ rather than ‘one-time spot removal’ attitude. (6) Sun protection is paramount — without it, any spot removal result is compromised.
Between pico laser and ND:YAG for spots, how does the physician choose for me?
Selection logic: (1) Spot type and depth — epidermal spots (sunspots, freckles) respond to both, but pico is more efficient with fewer sessions; melasma and deep spots favor pico’s low thermal injury; dermal pigment (nevus of Ota) needs long-wavelength pico or traditional lasers reaching the dermis. (2) Skin tone and PIH risk — darker or PIH-prone skin favors pico (minimal thermal injury); healthy skin with simple spots can also choose ND:YAG as an economical option. (3) Additional needs — wanting simultaneous improvement of pores, fine lines, and texture → choose pico with a focus lens (multi-effect device); pure spot fading → ND:YAG suffices. (4) Budget — ND:YAG costs less per session — those with limited budgets and superficial spots may start there and assess results. (5) Combined use — many cases benefit from ‘alternating’ over ‘single use’ (e.g., the melasma cocktail of low-fluence pico plus low-fluence ND:YAG). (6) Rappoel’s approach — diagnosing spot type and depth with a skin analyzer at consultation, fully explaining each option’s sessions, results, risks, and costs, and deciding together once you understand — ‘choose by evidence, not by price’ is our principle.
