Foundation can’t cover those spots? In Korea, Revlite laser vs. Pico – which one really works?

First things first – don’t get lost in “skin rejuvenation” and “fractional” hype

Every morning you look in the mirror, apply three layers of sunscreen, use half a bottle of concealer – yet the spots on your cheekbones still peek through. Even more frustrating, your overall complexion looks “dirty”, and that greyish tiredness can’t be hidden even with makeup.

In Korean dermatology clinics, the two most commonly used devices for these “pigment troubles” are Revlite laser (also called C10 laser) and Pico laser (PicoWay / PicoSure). Many people assume they’re similar, but they differ significantly in mechanism, targeted pigment depth, and recovery time. This article doesn’t hype or bash – it explains the principles, prices (in KRW), risks, and ideal candidates in plain language, so you can make an informed decision.

Two devices, two approaches

🔹 Revlite laser (nanosecond skin rejuvenation) – gentle “deep clean”

One‑sentence mechanism: Uses nanosecond (10⁻⁹ sec) 1064nm wavelength laser to break down pigment granules into smaller fragments via photothermal effect, which are then eliminated by the body’s metabolism. It focuses more on “overall skin tone evening” and “superficial spot” improvement.

• Procedure: Apply cooling gel, wear protective goggles, full‑face scanning pattern – usually 20‑30 minutes. Minimal pain – feels like a light rubber‑band snap. Common device in Korea is Revlite SI (C10), with some clinics offering upgraded versions.
• Pros: Virtually no downtime (only slight redness that fades within hours); gentle energy, suitable for regular full‑face maintenance; good for fading melasma with relatively lower risk of post‑inflammatory hyperpigmentation (PIH).
• Cons / limitations: Less effective for deep pigments (e.g., Ota naevus, deep dermal spots); requires multiple sessions (usually 4‑6) to see noticeable change; single session results are not “dramatic” – more of a gradual improvement.

🔸 Pico laser (ultra‑short pulse fragmentation) – precise “bomb disposal”

One‑sentence mechanism: Pulse width reaches picosecond level (10⁻¹² sec) – 1000 times shorter than nanosecond – producing powerful photomechanical shockwaves that shatter pigment into dust‑like particles, easier for the body to clear. More targeted for stubborn spots.

• Procedure: Topical anaesthetic applied (some find it slightly more painful), treatment takes about 15‑20 minutes. Common devices include PicoWay (widely used in Korea) and PicoSure (Fraxel Pico).
• Pros: Single session shows more obvious results, especially for sunspots, freckles, tattoos; can be combined with “Fraxel lens” to stimulate collagen, improving fine lines and pores; more thorough fragmentation of deep pigments.
• Cons / limitations: Post‑treatment may show whitish spots or mild purpura (subcutaneous bleeding); downtime slightly longer (3‑7 days of crusting); higher energy may exacerbate melasma (requires careful doctor handling); more expensive.

One table to cure your decision paralysis

⚠️ Table note: Prices are typical quotes from mainstream dermatology clinics in Seoul’s Gangnam district. Revlite may vary if neck is included; Pico prices differ by device (PicoWay vs PicoSure) and handpiece (flat scanning vs Fraxel lens) – the table shows flat‑scan reference. All are “full‑face single session” costs.

The real cost to your wallet – how much in KRW?

Don’t just look at the results – these trade‑offs are real

General risks for both light‑based treatments:

• Post‑inflammatory hyperpigmentation (PIH): Especially in darker skin types – if sun protection is inadequate post‑op, temporary darkening may occur, usually fading in 1‑3 months.
• Burns / blisters: Overly high energy or poor technique can cause epidermal burns and scarring. Always choose an experienced dermatologist for the procedure.
• Hypopigmentation (white spots): In rare cases, over‑treatment may damage melanocytes, leading to permanent white spots – risk slightly higher with Pico than Revlite.
• Unsatisfactory results: Melasma itself is prone to recurrence – laser alone cannot “cure” it; oral and topical adjuvant therapies are needed.

Not suitable for: Photosensitive skin, recent sun exposure, pregnancy or breastfeeding, keloid tendency, active infections (e.g., herpes) – postpone treatment.

After treatment – DON’T do these “self‑sabotaging” moves

Days 0‑7 (applicable to both):

• Sun protection is priority #1: Strict physical protection (hat + mask + sunglasses) + SPF50+ PA++++ sunscreen – apply before going out, and reapply indoors as well.
• Gentle cleansing: Avoid washing your face for the first 24 hours (use saline wipes if needed), then use a mild amino‑acid cleanser with lukewarm water.
• Moisturise and repair: Use medical‑grade repair dressings (containing ceramides, hyaluronic acid) generously – at least one sheet mask per day (refrigerated is better).
• Avoid: No exfoliation, chemical peels, saunas, or intense exercise (to reduce sweating) for a week. After Pico, let any crusts fall off naturally – DO NOT pick them!
• Diet: Avoid spicy foods, seafood, and photosensitive foods (e.g., celery, parsley). Supplement with vitamins C and E to help with melanin clearance.
