Many buyers struggle to separate marketing language from cleared labeling and published outcomes. A "pico" label tells you pulse duration, not whether the system fits your service mix.
This guide explains how PicoWay works, compares tattoo and pigment use, and gives you a framework for checking evidence, FDA labeling, specifications, and ownership costs.
Key Takeaways
- Match verified wavelengths, handpieces, and labeling to your intended treatments, not the "pico" label.
- Tattoo outcomes vary with ink color, depth, age, and patient biology.
- Pigmentation needs accurate diagnosis and skin-type-aware settings.
- Weigh evidence, training, service, warranty, and total ownership cost before buying.
What Is PicoWay and How Does It Work?
PicoWay is Candela’s picosecond laser platform for tattoo and pigmentation removal, with fractional handpieces for concerns such as acne scars and wrinkles. It delivers ultra-short pulses across multiple wavelengths so operators can match energy delivery to ink color, pigment depth, and skin type.
How PicoWay targets pigment
Picosecond pulses rely on a photoacoustic effect. Energy arrives so fast that ink or melanin shatters into fine particles before heat spreads widely.
The body then clears the fragments over time through transepidermal elimination and macrophage uptake, as a peer-reviewed review describes. The American Academy of Dermatology notes the body needs time to flush tattoo ink.
Longer-pulse and nanosecond systems lean more on thermal energy. Picosecond treatment is still not heat-free, and it does not eliminate discomfort, complications, or the need for multiple sessions.
Wavelengths and handpiece configurations
Candela lists four wavelengths: 532, 730, 785, and 1064 nm. Nominal pulse durations run roughly 250 to 450 ps depending on wavelength.
| Handpiece / wavelength | Spot size | Beam format |
|---|---|---|
| Zoom, 532 and 1064 nm | 2-10 mm | Full beam |
| Dedicated 730 and 785 nm | 2, 3, 4 mm | Full beam |
| Resolve, 532 / 1064 nm | 6 x 6 mm | Fractional micro-beam |
| Resolve Fusion, 532 nm | 6 x 6 mm | Micro-beam with diffuse ring |
Zoom and dedicated applicators serve tattoo and pigment work. Resolve and Resolve Fusion target fractional applications such as acne scars and wrinkles. Pulse figures vary by source, so confirm exact specs for your quoted configuration against current manufacturer documentation and FDA records.
Operator dependence
Fluence, repetition rate, spot size, density, cooling, and skin type are provider decisions, not fixed platform benefits. Burns, dyspigmentation, scarring, incomplete clearance, and worsened pigmentation remain possible with poor selection or technique.
A Candela-sponsored protocol lists:
- Burning and blistering
- Hyper- and hypopigmentation
- Infection
- Scarring
PicoWay for Tattoo Removal
Tattoo characteristics that shape outcomes
Assess these at consultation:
- Ink colors and pigment depth
- Density, tattoo age, and cover-ups
- Body location and scarring history
- Medications and general health
Wavelength matters by color. Current US labeling lists:
- 532 nm for red, yellow, and orange
- 730 nm and 785 nm for green and blue
- 1064 nm for black, brown, green, blue, and purple
The 1064 nm tattoo labeling covers all Fitzpatrick types. No complete removal is promised for any color.
What the evidence shows
| Study | Findings | Limits |
|---|---|---|
| 2015, PicoWay 532/1064 nm | 21 subjects; mean 79% clearance after 6.5 treatments | Mild pigment change in 6 of 31 tattoos; manufacturer-funded |
| 2018, PicoWay 785 nm | Blue 81%, green 74%, black 61%, red 11%, yellow 5% after 4 treatments | Small, uncontrolled, manufacturer-funded |
These are sponsored cohorts, and 79% is not complete removal.
PicoWay versus Q-switched lasers
A 2022 systematic review of 36 studies supports both picosecond and Q-switched Nd:YAG for black tattoos and favors picosecond for blue, green, and yellow.
The evidence is heterogeneous, and it measures the class, not PicoWay specifically. Treat claims like "50% fewer sessions" with caution unless independent trials support them.
Planning and expectations
Tattoo removal is staged. PicoWay cohorts spaced sessions 6 to 10 weeks apart, which reflects research exposure rather than a universal protocol. Expect gradual fading, not guaranteed total removal.
Good practice includes:
- Consultation with scar and medication history
- Wavelength-specific eye protection
- Test spots when clinically appropriate
- Sun avoidance and aftercare (the AAD advises protecting treated skin for 3 months)
A 2018 PicoWay trial excluded keloid or hypertrophic scarring history, active infection, recent retinoids, pregnancy, and active tanning. Those are trial exclusions, not a full contraindication list.
PicoWay for Pigmentation Removal
Match treatment to the pigment type
Not every dark spot suits cosmetic laser treatment. Distinguish lentigines, freckles, café-au-lait macules, post-inflammatory hyperpigmentation, melasma, and dermal pigment before choosing parameters. Suspicious lesions need medical evaluation first. Depth, concentration, and recurrence risk drive wavelength choice and session count.
Keep the evidence separate by category:
- Solar lentigines (730 nm, 2022): mean improvement 51%-75% after up to 4 sessions; mild PIH in 4 of 20; Candela-funded.
- Café-au-lait macules (730 nm, 2024): 14 patients, types II-VI; mean 26%-50% improvement; 3 partial recurrences and one mild persistent hypopigmentation.
- Melasma (2023 randomized trial): PicoWay 1064 nm gave 35.9% MASI improvement at week 24, versus 25.5% for PicoSure 755 nm and 24.0% for 2% hydroquinone. Government-funded, types III-IV.
- Nevus of Ota (1064 nm, 2021): 16 patients, PIH in 1 of 16.
Skin of color
More epidermal melanin raises the stakes. Use conservative settings, cooling, test areas, and close follow-up. PicoWay may deliver less thermal exposure than some alternatives, but it is not risk-free for Fitzpatrick IV-VI. No precise type VI complication rate has been established, and pigment labeling is narrower than tattoo labeling.
Results, recurrence, and maintenance
Discrete lesions respond differently from diffuse, hormonally influenced melasma. Improvement builds gradually. The AAD recommends shade, a wide-brimmed hat, and broad-spectrum SPF 30+ for melasma. Some melasma persists despite treatment. Permanent clearance is not established, so plan for ongoing care.
FDA boundaries
| 510(k) | Date | Relevance |
|---|---|---|
| K162454 | Feb 2017 | Tattoo and benign pigment indications |
| K191685 | Sept 2019 | Adds 730 nm; Resolve configurations |
| K220853 | Oct 2022 | Expanded lesion labeling, including melasma |
Under current labeling, benign pigmented lesions are cleared for types I-IV. Melasma is cleared for 532/1064 nm and Resolve 1064 nm, I-IV. Lentigines are cleared at 532/730 nm, café-au-lait macules at 532 nm, and nevus of Ota at 1064 nm for types III-IV.
Melasma is therefore not categorically off-label, but applications outside the specified wavelength, handpiece, and phototype are not cleared. The 730 nm café-au-lait study falls outside the explicit 532 nm labeling.
Evaluating PicoWay for a Practice
Build a procurement checklist
Document your intended services first. Then verify that the quoted configuration covers your tattoo colors, pigment conditions, wavelengths, handpieces, spot sizes, modes, and safety features. Do not assume a used unit matches current marketing.
Compare PicoWay with PicoSure
| Dimension | PicoWay | PicoSure / PicoSure Pro |
|---|---|---|
| Wavelengths | 532, 730, 785, 1064 nm | 755 nm core; optional 532/1064 nm |
| Spots | Zoom 2-10 mm; 730/785 nm 2-4 mm | Zoom 2-6 mm; fixed 5-10 mm |
| Pigment scope | Multi-wavelength tattoo and pigment | 755 nm tattoo and pigment, including melasma |
The 2023 melasma trial compares the brands directly but does not establish tattoo superiority. Also compare training, software, ergonomics, service response, and your patient mix.
Assess ownership risk and total cost
Published US list pricing is scarce. Quotes for a well-configured new system often range from roughly $150,000-$210,000 to $250,000-$325,000, so get written quotes. Price these items:
- Equipment, installation, and separately priced handpieces
- Dedicated 200-240 VAC service and room planning (the unit weighs 125 kg, or about 275 lb)
- Training, maintenance, calibration, and service contracts
- Warranty terms (one year is advertised; confirm parts, labor, travel, and handpiece coverage)
- Financing, insurance, downtime, and utilization assumptions
Used equipment needs verified condition, accessories, service history, and support eligibility. Candela's own used-laser guide warns about third-party tampering, though it is vendor advice. Operator rules also vary by state. California, for example, allows physicians, or RNs and PAs under supervision, but not cosmetologists.

Frequently Asked Questions
How does the PicoWay laser work?
It delivers picosecond pulses that fragment tattoo ink or melanin photoacoustically. The body clears the particles gradually. Results depend on the pigment treated and the settings chosen.
How long does it take to see results from PicoWay?
Tattoos should lighten after each treatment, but full clearance takes multiple sessions spaced weeks apart. Timing varies with indication, pigment depth, skin response, and treatment plan.
What's the difference between PicoSure and PicoWay?
PicoWay offers 532, 730, 785, and 1064 nm; PicoSure centers on 755 nm with optional 532/1064 nm. Compare handpieces, pulse specifications, cleared indications, and evidence for your applications. Neither is universally superior.
Is the PicoWay laser worth it?
It depends on patient demand, treatment mix, utilization, operator training, service support, and total ownership cost. Model these with written quotes before deciding.
Is PicoWay a good laser for tattoo removal?
It can work well for selected colors, especially with the right wavelength. Results vary, and complete removal is not guaranteed.
