PicoWay Laser Tattoo Removal: How It Works & What to Expect
PicoWay Laser Tattoo Removal: How It Works, How Long It Takes, and What Results Actually Look Like
PicoWay is a picosecond laser that breaks tattoo ink into dust-sized fragments using ultra-short pulses — faster and with less heat than older lasers. It works on all skin tones and clears a wider range of ink colors than most systems on the market. That said, it's not a one-and-done treatment. Depending on your tattoo's size, color, and age, you're looking at anywhere from 4 to 15 sessions spaced 6 to 10 weeks apart. This article walks through exactly what the process involves, what affects your results, and what honest expectations look like.

How laser tattoo removal actually works
Tattoo ink sits in the dermis, the deeper layer of skin, and your immune system can't clear it on its own — the particles are simply too large. Laser tattoo removal works by delivering concentrated light energy into those ink particles, shattering them into fragments small enough for your body's lymphatic system to carry away over the following weeks.
The process isn't instant. After each session, your immune system does the actual work of clearing the fragmented ink. That's why sessions are spaced 6 to 10 weeks apart. Rushing them doesn't speed up results — it just means the ink from the previous session hasn't fully cleared yet.
Different ink colors absorb different wavelengths of light. Black ink absorbs nearly all laser wavelengths, which is why it responds fastest. Lighter colors and certain pigments are more selective, requiring specific wavelengths to break them down effectively. This is one reason the laser used matters — a lot.
Why PicoWay outperforms older tattoo removal lasers
The core difference is pulse duration. Older Q-switched lasers fire in nanoseconds — billionths of a second. PicoWay fires in picoseconds, which are one trillionth of a second. That's roughly 100 times faster.
Why does that matter? Shorter pulses mean less heat transferred to surrounding tissue. The energy hits the ink particle so quickly that the ink shatters through a photoacoustic effect (mechanical pressure) rather than being burned. Less heat means less risk of scarring, less damage to surrounding skin, and a cleaner treatment overall.
The practical results: PicoWay clears ink in fewer sessions for most tattoos, handles difficult colors like blues, greens, and yellows that older lasers often can't touch effectively, and is safer for people with medium-to-dark skin tones, where heat-based lasers carry a real risk of post-inflammatory hyperpigmentation.
PicoWay also uses multiple wavelengths, giving it the flexibility to target a broader color spectrum within a single treatment system. Many older laser systems are single-wavelength, which limits what they can address.
How many sessions you'll need (and why the number varies so much)
There's no single answer here, and anyone who gives you a firm number without seeing your tattoo is guessing. The range is genuinely wide: 4 sessions on the low end for small, faded, single-color tattoos; 15 or more for large, heavily saturated professional work.
The factors that matter most:
- Ink density. A professional tattoo applied with a machine at high saturation holds far more ink than an amateur tattoo or something older that has already faded.
- Ink color. Black clears fastest. Blues, greens, and yellows take longer.
- Tattoo age. Older tattoos have often already begun to fade naturally, which gives the laser a head start.
- Location on the body. Areas closer to the heart with better circulation tend to clear faster than extremities like ankles or fingers, where lymphatic flow is slower.
- Your immune system. People who are generally healthy, hydrated, and active tend to clear ink more efficiently. Smoking slows the process noticeably.
- Skin tone. Providers working with darker skin tones often use lower energy settings to protect the skin, which can mean additional sessions.
A good estimate for a straightforward black tattoo from a professional artist: 6 to 10 sessions. A small amateur tattoo: 4 to 6. A large, colorful sleeve: plan for 12 or more and think of it as a long-term project.
Which ink colors are easiest (and hardest) to remove
Black and dark gray are the most responsive. They absorb the widest range of laser wavelengths, so the treatment hits effectively regardless of which system is used. Most black-ink tattoos show significant fading within the first few sessions.
Red, orange, and brown inks typically respond well too, though they require the right wavelength targeting. Dark blue often clears reasonably well. Where it gets harder:
- Bright green and teal. These are among the most resistant colors. Older lasers often can't break them down at all. PicoWay handles them better, but expect more sessions.
- Yellow and light green. These pigments don't absorb laser energy as readily, so each session delivers less fragmentation. Progress is slower.
- White ink. White ink can paradoxically darken when treated with certain lasers, because it often contains titanium dioxide that oxidizes under laser exposure. It requires careful assessment before treatment.
- Fluorescent or UV-reactive inks. These contain specialty pigments that may not fully respond to any currently available laser system.
If your tattoo contains multiple colors, the treatment plan will account for that. Some colors within the same tattoo may clear in 6 sessions while others are still present at 10. That's normal — it doesn't mean the treatment isn't working.
What to expect during and after each session
Before the session starts, numbing cream is applied to the area and left on for 20 to 30 minutes. During treatment, most people describe the feeling as a rubber band snapping against the skin in rapid succession. It's not pleasant. It's also not intolerable, and the session itself is short — typically 10 to 30 minutes for most tattoo sizes.
When the laser hits the skin, you'll see a white "frosting" reaction: a temporary whitening of the skin surface that fades within minutes. That's a normal sign the ink is responding to the energy.
Immediately after, the area will be red and swollen, similar to a mild sunburn. Small blisters over the following 24 to 48 hours are a normal part of the skin's healing response — keep the area clean and don't pop them. Significant blistering, spreading redness, or pain that worsens after the first 48 hours are not normal and should prompt a call to your provider.
Aftercare:
- Keep the area clean and covered for the first 24 to 48 hours.
- Apply a thin layer of healing ointment (like Aquaphor) as directed.
- Avoid submerging the treated area in water for at least two weeks.
- Stay out of direct sun on the treated area for a minimum of four weeks.
- Don't pick at any blisters or scabs that form.
The first few days look the worst. By the end of week two, redness has typically resolved. By week six or eight, you can start to assess how much clearing has occurred before your next session.
"The most common thing I hear from patients is that they expected it to be faster. Tattoo removal is a slow process by design — your immune system does the clearing, and that takes time. What PicoWay changes is how efficiently each session breaks the ink down, which ultimately reduces the total number of sessions most people need. But the timeline between sessions stays the same because biology doesn't compress. Patience is genuinely part of the treatment."

Is PicoWay tattoo removal safe for darker skin tones?
Yes, with an important qualifier: it requires a provider who understands how to calibrate settings appropriately for Fitzpatrick skin types IV through VI.
The risk with any laser treatment on medium-to-dark skin is post-inflammatory hyperpigmentation (PIH): the skin produces excess melanin in response to thermal injury, leaving a darkened patch that can persist for months. PicoWay's picosecond technology delivers less heat to surrounding tissue, which is why it's a better option for darker skin types.
Providers working with darker skin tones typically use more conservative energy settings, which sometimes means progress is more gradual. A test spot is often done first. This is standard practice and a sign of good clinical judgment.
PicoWay is also used for treating hyperpigmentation and melasma — the same properties that make it gentler on melanin-rich skin make it effective for those concerns as well. If you've been told laser tattoo removal isn't for your skin tone, that's worth a second opinion.
Partial fading vs. full removal: what's possible with PicoWay
Full removal means the tattoo is no longer visible. That's achievable for most tattoos with enough sessions, though some residual ghosting can remain, particularly with heavily saturated professional work. Complete clearance isn't guaranteed, and it's honest to say that upfront.
Partial fading is a separate goal with a shorter timeline. If you want a cover-up tattoo and your current tattoo is too dark or saturated for an artist to work over, a few PicoWay sessions can lighten it enough to give your tattoo artist a usable canvas. Typically 2 to 4 sessions achieves meaningful fading for cover-up purposes. You don't need to chase full clearance if your end goal is just to create room for new work.
The PicoWay laser is also precise enough to target isolated sections of a tattoo without affecting adjacent areas, making selective removal possible. Knowing which goal you're working toward helps set realistic expectations from session one.

Frequently asked questions
Does laser tattoo removal hurt?
Most people describe it as a rubber band snapping against the skin, repeated quickly over the tattooed area. It's uncomfortable but brief. We apply numbing cream beforehand to reduce the sensation, and each session is short — typically 10 to 30 minutes depending on tattoo size. The discomfort is real. It's also manageable for most people.
How much does PicoWay tattoo removal cost?
Cost depends on tattoo size, color complexity, and the total number of sessions needed. A small, faded black tattoo costs far less overall than a large multi-color piece requiring 12 or more sessions. We provide personalized pricing at consultation once we've assessed your tattoo directly.
Can PicoWay remove all tattoo colors?
PicoWay handles a broader color range than most tattoo removal lasers, including difficult colors like blues, greens, and yellows that older systems often can't touch. Black and dark gray clear fastest. Some specialty inks, particularly fluorescent or UV-reactive pigments, may not fully respond to any available laser.
How long does each session take?
The laser treatment itself runs 10 to 30 minutes for most tattoo sizes. Add 20 to 30 minutes beforehand for numbing cream, plus a brief post-treatment review. Plan for roughly an hour per visit.
Will laser tattoo removal leave a scar?
Scarring is uncommon when the treatment is performed correctly. PicoWay's picosecond pulses deliver less heat to surrounding tissue than older nanosecond lasers. One thing to know: if the original tattoo was applied over scarred skin, that scarring will remain visible after the ink clears. The laser removes ink, not pre-existing scar tissue.
Can I remove a tattoo partially for a cover-up?
Yes, and this is one of the most practical uses of PicoWay tattoo removal. If your existing tattoo is too dark or saturated for a cover-up to work well, a few sessions can lighten it enough for your tattoo artist to do their job effectively. Two to four sessions typically creates enough fading for cover-up purposes.
How soon can I be in the sun after treatment?
Avoid direct sun exposure on the treated area for at least four weeks after each session. The skin is healing and significantly more vulnerable to hyperpigmentation during that window. SPF 30 or higher is required if you're outside. Tanning beds are off the table throughout your entire course of treatment.
