The Korean medical device the world doesn\'t yet know
Korean medical device manufacturing has produced globally-significant products that consumers rarely hear of. Laseroptek is one example — a South Korean medical laser company that developed PicoLO, a picosecond laser device that competes directly with industry giants like Cynosure (PicoSure) and Candela (PicoWay). The original PicoLO received the Minister of Trade, Industry and Energy Award at the 2019 Korea Technology Awards. The newer PicoLO Premium is among the most-used picosecond laser devices in Korean dermatology in 2026.
Picosecond laser technology is the gold standard for tattoo removal in 2026. Understanding which device your Korean clinic operates matters because device generation and specific technology differ in clinical performance.
Picosecond vs nanosecond laser physics
Laser pulse duration determines the energy delivery profile:
- Nanosecond (Q-switched) lasers: energy delivered in 10⁻⁹ seconds, creates thermal effect, established technology since 1990s
- Picosecond lasers: energy delivered in 10⁻¹² seconds (1000x faster), creates photoacoustic effect with less thermal damage
The clinical implications:
- Picosecond fragments pigment more efficiently (smaller particles for body clearance)
- Less thermal damage means less risk of post-inflammatory hyperpigmentation
- Faster treatment completion (fewer sessions needed)
- Better for difficult-to-remove tattoo colors
- Safer for darker skin tones
PicoLO Premium specifications
- Pulse duration: 350–450 picoseconds
- Wavelengths: 532 nm, 1064 nm
- Dual-wavelength capability for diverse pigment colors
- Adjustable spot size for precision treatment
- Multiple treatment modes for various indications
- Touch-screen interface for parameter control
What PicoLO treats well
Tattoo removal
Multi-color tattoos benefit from dual-wavelength capability:
- 1064 nm: dark pigments (black, blue, green)
- 532 nm: red, orange, yellow, brown pigments
- Specialty handpieces: for shallow surface pigment
Typical course: 5–10 sessions for complete removal, 6–8 week intervals.
Pigmentation treatment
- Melasma (gentle settings)
- Post-inflammatory hyperpigmentation
- Sun-induced age spots (lentigines)
- Cafe-au-lait macules
- Nevus of Ota (deep dermal pigmentation)
- Skin rejuvenation through low-density treatment
Skin texture and tone
- Pore reduction
- Fine wrinkle improvement
- Acne scar improvement (mild)
- Skin brightening
- General skin rejuvenation
What PicoLO doesn\'t treat well
- Deep wrinkles (need stronger ablative treatment)
- Significant acne scars (better with RF microneedling or micro-coring)
- Vascular lesions (need vascular laser)
- Hair removal (different device type)
- Severe skin laxity
The Korean PicoLO procedure
- Skin cleansing and treatment area preparation
- Topical numbing for 20–30 minutes (variable by treatment)
- Wavelength and parameter selection based on indication
- Laser passes over treatment area
- Real-time skin response monitoring
- Cooling and calming application post-treatment
- SPF before patient leaves
- Total appointment: 30–60 minutes

Skin rejuvenation
- Single rejuvenation session: ₩150,000–350,000
- Often packaged with other treatments
Recovery
Tattoo removal
- Day 0: redness, slight swelling, possible pinpoint bleeding
- Day 1–7: scab formation at treatment site
- Day 7–14: scab natural loss
- Week 2–4: slight redness fading
- Week 6–8: ready for next session
- Result becomes apparent gradually as pigment clears
Pigmentation/rejuvenation
- Day 0–1: mild redness
- Day 2–7: pigment darkening before clearing
- Week 2–4: visible improvement
- Month 1–3: continued result emergence
Comparison with other picosecond lasers
| Device | Origin | Pulse duration | Wavelengths |
|---|---|---|---|
| PicoLO Premium | Korea (Laseroptek) | 350–450 ps | 532, 1064 nm |
| PicoSure | US (Cynosure) | 550–750 ps | 755, 532, 1064 nm |
| PicoWay | US (Candela) | 300–450 ps | 532, 785, 1064 nm |
| Discovery PICO | Italy (Quanta) | 250–450 ps | 1064, 532, 694 nm |
| Enlighten | US (Cutera) | 670–750 ps | 532, 1064 nm |
PicoLO Premium\'s pulse duration is comparable to leading global devices. The Korean availability and pricing make it particularly attractive at Korean clinics.
Why Korean clinics use Korean-made devices
- Lower equipment cost passed to patients
- Local manufacturer support and maintenance
- Familiar device language and interface
- Training and education infrastructure
- Comparable performance to imported alternatives
- Strong domestic supply chain for replacement parts
Patients shouldn\'t assume imported devices are categorically better — for picosecond laser technology, Korean-developed devices compete on equivalent terms with global brands.
Verification: Is your clinic using authentic PicoLO?
Counterfeit medical devices appear at discount clinics. Verification:
- Authentic devices display Laseroptek branding and serial numbers
- Treatment parameters and interface match official specifications
- Clinic registered with Laseroptek customer support
- Significantly lower-than-market pricing may indicate counterfeit
- Treatment cartridges or consumables purchased from authorized distributors
Treatment course planning
Tattoo removal course
- Initial consultation including photo documentation
- Wavelength selection per ink color
- 5–10 sessions at 6–8 week intervals
- Cost amortization across sessions
- Final result evaluation at 6 months after last session
Pigmentation course
- Initial consultation with Wood\'s lamp assessment
- 5–10 gentle sessions
- Skincare protocol between sessions (niacinamide + TXA serum, SPF)
- Maintenance schedule based on response
Combining PicoLO with other modalities
- + Niacinamide + TXA serum (daily): sustained pigment reduction
- + Sunscreen (mandatory): protect treated skin
- + RF microneedling (separate session): for combined texture + pigment cases
- + Chemical peels (occasional): exfoliation enhancement
- + Glutathione protocols: for systemic brightening
Side effects and risks
- Temporary redness (universal)
- Post-inflammatory hyperpigmentation (lower with picosecond than nanosecond)
- Temporary darkening before pigment clearance
- Blistering or scarring (rare with proper parameters)
- Pigmentary changes at high settings
- Tattoo allergic reaction (very rare during treatment)
Who is a good candidate?
- Tattoo removal patients with realistic expectations about session count
- Pigmentation patients across most Fitzpatrick types
- Melasma patients (with gentle protocol)
- Skin rejuvenation seekers
- Patients with established acne scars and pigmentation overlap
Wrong candidates
- Active acne
- Pregnancy or breastfeeding
- Recent isotretinoin use (wait 6 months)
- History of keloid scarring
- Significant medical comorbidities
- Patients with unrealistic expectations about result speed
Honest framing
PicoLO Premium is a competent Korean-developed picosecond laser delivering results comparable to imported global brands. The clinical performance advantages of picosecond vs nanosecond laser technology are real. For Korean patients, PicoLO offers excellent value at lower cost than imported devices. International patients should verify clinic device authenticity and operator experience rather than focus on device brand alone — operator skill matters more than device generation in producing good results. For tattoo removal specifically, multi-session commitment is essential; expectations of 1-2 session removal are unrealistic regardless of device. For pigmentation treatment, daily skincare maintenance between sessions amplifies results meaningfully.
