Pico Laser Before and After: Results, Photos and Recovery

Stay In The Know

Expert advice. Very good deals. The absolute best (and worst) things we've tested lately.

Pico laser before and after photos show how pigment, tattoo ink or acne scarring changes across a series of picosecond laser sessions, and an honest set always tells you how many sessions, how far apart, and what else was done.

That last part is where most galleries fall down. A tattoo can look “gone” across two pictures when the clinic’s own notes say nine visits over about a year, and none of that makes it into the caption.

We’ve split this up by the four things people type into Google most, pigmentation, melasma, tattoos and acne scars, and under each one you get what the published work actually backs up and what an honest result usually looks like in a photo. We also cover how a clinic should shoot and label its own cases so the photos hold up.

Pico Laser Before and After Case Gallery

Each case published here will carry the same card, so you can compare like with like:

Field	What goes in it
Concern	e.g., solar lentigines, black professional tattoo
Area	e.g., left cheek, right forearm
Skin type	Fitzpatrick type, if documented
Sessions	Total number in the photo set
Interval	Weeks between sessions
Device / wavelength	Only if verified from treatment records
Settings	Only if supplied and approved by the treating clinician
Photo timing	Days or weeks between baseline and “after”
What improved	Observed change, in plain words
Still there	Leftover pigment, ghosting, uneven texture
Combined treatments	Any other laser, topical or device used

If a case shows up with half of those boxes blank, it doesn’t go up on this page.

What Pico Laser Before-and-After Photos Can and Can’t Tell You

Two photos side by side are one person’s skin, one body area and one clinician’s choices on those days. They don’t predict yours.

The research behind those pictures is decent for some uses and thin for others. When Reiter’s group pulled the tattoo trials together for Lasers in Medical Science in 2016, they found that 69 to 100% of tattoos in the human studies reached more than 70% clearance after 1 to 10 treatments. They also said, fairly bluntly, that evidence of picosecond beating nanosecond lasers was sparse, and that most trials carried medium to high risk of bias.

So read a gallery the way you’d read a small case series. Useful. Not proof.

How Results Differ by Treatment Type

Concern	What change usually looks like	Pace	Main caveat
Lentigines, sun spots	Goes darker, crusts, flakes; lighter once healed	Often shows by visit 1–2	More sun, more spots
Melasma	Slow, blotchy lightening	Across a series	Comes back a lot; can flare
Black tattoo	Overall fading, then patchy “ghost”	Steady over many sessions	Dense or layered ink takes longer
Colored tattoo	Colors fade at different rates	Uneven; wavelength-dependent	Some inks resist every wavelength
Acne scars, texture	Softer edges, smoother surface	Gradual over a series	Deep scars change least

Pico Laser Before and After Photos by Treatment Type

Pigmentation and Sun Spots

Lentigines are usually where the most convincing photos come from, and with good reason. The spot sits in the epidermis, it absorbs well at 532 nm, and the change is easy to see.

Right after treatment, the spot often goes darker. Over roughly the next week or so it crusts and sheds. A fair “after” photo is the one taken once that crust is gone and the redness has settled, not on day three.

Ungaksornpairote and colleagues ran a split-face study in Asian patients that included lentigines and acquired bilateral nevus of Ota-like macules, with picosecond on one side and Q-switched Nd:YAG on the other. At six months, 85.7% of picosecond-treated sides had improved by more than half, against 57.2% on the Q-switched side. Fourteen patients in total. Keep that number in mind before quoting it to anyone.

For other ways clinics handle spots, see our guide to laser treatment for dark spots.

Melasma

Melasma “before and after” photos deserve the most suspicion. A dramatic single jump should make you ask what else was going on, and when the “after” was taken.

Feng’s group put six randomized trials together in 2023 and the 1064 nm arms did bring MASI and mMASI scores down. The 755 nm arms didn’t beat plain topical lighteners, though, and some of those patients ended up with post-inflammatory hyperpigmentation. Heterogeneity sat at I² 70%, so we wouldn’t stretch the headline too far.

An honest melasma pair tends to be underwhelming at first glance. The patch is a shade lighter and a little less blotchy, the caption mentions the sunscreen and the cream she was on, and if the clinic is really doing it right there’s a third photo from the following summer showing whether it crept back. Our laser treatment for melasma guide covers device choice in more depth.

Tattoo Removal

Of the four, tattoo sets are the easiest to read, as long as nobody skips the middle photos or leaves the dates off.

Right after the pass the ink goes white for a few minutes, the frosting everyone posts on Instagram. Then comes swelling and pinpoint bleeding, sometimes a blister or two. The AAD makes the point that skin has to heal between visits, and that’s part of why nobody finishes in one. The fading you can actually photograph turns up weeks later, once macrophages have carted the fragments off, so a same-day shot shows the reaction, not the result.

Ink color changes the pace. Back in 2012 Brauer’s team (Archives of Dermatology) took 12 tattoos with blue or green in them, used a 755 nm picosecond laser, and got at least 75% of those colors out of every one within a session or two. A newer review in the Journal of the American Academy of Dermatology (2020) found both picosecond and Q-switched Nd:YAG safe and effective for black ink, with picosecond ahead for blue, green and yellow.

When a tattoo stalls, it’s usually that last faint ghost, or a cover-up with two layers of ink on top of each other, or a brow tattoo where the pigment can actually turn darker under the laser. A caption that admits “faint residual ink at session 8” is more believable than one that doesn’t. If you want to know what the arm looks like in week two or week five, our laser tattoo removal healing stages piece has it.

Pico Plus Acoustic Shock Waves

You’ll see galleries that pair pico with acoustic shock wave therapy. The best-known published example is a single case: Vangipuram, Hamill and Friedman (2018, Lasers in Surgery and Medicine) treated one black wrist tattoo in a type V patient over three sessions. The half that also received shock wave therapy reached about 80% clearance; the laser-only half about 60%.

One patient, one tattoo. Interesting, but not a protocol. If a clinic posts photos from combination treatment, the caption has to say so.

Acne Scars and Skin Texture

Scar photos need side lighting to be fair. Flat front light can make almost any face look smoother, and a light angle that shifts between visits can invent a result.

Ask a clinic which paper they lean on and it’s usually Brauer again, this time in JAMA Dermatology (2015). Twenty people with facial acne scars had six rounds with a 755 nm picosecond laser fitted with a diffractive lens array, and three dermatologists who didn’t know which photo was which put the overall improvement at 25 to 50% a month after the last session. Three months out, it was still there.

A typical scar series looks like gradual softening of rolling and boxcar edges. Deep icepick scars change least. Handpiece choice and how clinics space the series are in our pico laser for acne scars write-up.

When You Can Actually See a Pico Laser Result

We’d want a photo from each of these three moments before calling anything a result.

Same day. Skin’s red and puffy, a tattoo is frosted white for a few minutes, and sun spots often look darker than they did that morning, so don’t post this one as an “after.”
Once it’s healed. The crust has come off and the pink has gone. A lentigo often looks clearly lighter by now, and a tattoo shows its first bit of fade.
After a series: The real comparison. For tattoos, melasma and scars, this is the only “after” worth publishing.

How Many Treatments May Be Needed?

There isn’t one schedule for everything, and we’d be wary of any page that gives one.

Tattoos in the systematic review needed anywhere from 1 to 10 sessions to pass 70% clearance, depending on the study. The Brauer acne scar trial used six. Lentigines often respond sooner. Melasma is managed more than finished.

How far apart the visits go is the treating clinician’s call, and it shifts with the condition and with how fast that person’s skin settles down. A gallery caption should state the actual interval used for that patient.

Why Two Patients Get Different Pico Laser Results

Pigment type and depth. A freckle sitting near the surface moves quicker than something deep like nevus of Ota, and melasma plays by its own rules.
Tattoo composition. A stick-and-poke from a friend’s kitchen is a different job from a saturated professional piece, and a cover-up is different again.
Skin type. On type IV to VI skin, 532 and 755 nm make post-inflammatory hyperpigmentation more likely, so most clinicians dial back.
Technique. Two operators on the same machine won’t pick the same spot size or stop at the same endpoint.
Aftercare. A patient who skips sunscreen in July can lose months of progress.

PicoSure Before and After vs. Other Pico Laser Systems

PicoSure belongs to Cynosure, not to us. The FDA cleared it for tattoo removal toward the end of 2012, and pigmented lesions and wrinkles were added in later clearances. Many of the “picosure laser before and after” images online come from clinics using that platform.

Those photos tell you what one brand of device did in one clinic’s hands. Swap in a different machine and you can’t assume the same thing happens, and that cuts both ways, since the wavelengths, pulse lengths, energy and tips all differ from one platform to the next, and so does whoever’s holding the handpiece.

Shopping for a device? Put the measured specs and the published papers side by side and leave the galleries out of it. Our PicoSure machine cost and alternatives guide and the pico vs Q-switched tattoo removal machine comparison cover the buying side.

Shooting Before-and-After Photos That Hold Up

There’s a handy 2017 paper in the International Journal of Dermatology about doing standardized procedure photos with ordinary gear, and what it boils down to is that whatever you did for the “before” (room, camera, who’s shooting, how the patient sits, how you frame it) you do again for the “after.”

Day to day, that looks like this:

One camera. A phone is fine if it’s the same phone each time, at the same zoom and distance.
Same lighting. Fixed lights, no window daylight that changes by season. Side light for texture, kept identical between visits.
Same pose and background. Tape marks on the floor help, and the patient comes in without makeup or earrings, hair pulled back.
Hands off in editing. Correcting color against a gray card is fine, but nobody touches the skin.
Captions on everything. Put the date and session number on every photo, plus how many weeks it’s been since the last visit.

Consent and Image Use

HIPAA lists full-face photos and comparable images among its identifiers, so a U.S. clinic that wants to put them on its website or Instagram needs the patient’s written authorization first. The better consent forms say plainly where the pictures could end up, from the chart to a conference slide, whether the face will be visible, and how the patient takes it all back later.

Advertising adds another layer. The FTC wants evidence behind health claims in ads, and a before-and-after picture counts as a claim even when nobody writes one, so a gallery stacked with the three best cases out of a hundred is asking for trouble.

Recovery, Side Effects and Safety

Expect to leave red and a bit swollen; for most people that’s settled somewhere between that evening and a few days later, and tattoo areas may blister or crust on top of that.

Going back to Reiter’s review, the tattoo trials logged things like pain, blistering, pinpoint bleeding, some swelling and temporary redness, and color changes in the skin, mostly on the mild end. What we’d actually worry about is skin going darker or lighter than the area around it, more often in darker skin types, and melasma getting worse instead of better.

If the burning is worse on day two than day one, or blisters are spreading, the skin’s weeping, the redness is creeping outward or there’s a fever, the patient needs to ring the clinic that treated them. One more thing we won’t budge on: nobody lasers a pigmented spot until somebody has diagnosed it.

FAQs

How soon will I see pico laser before and after results?

Sun spots often look lighter once the crust sheds, usually within a couple of weeks of a session. Tattoos fade gradually over the weeks after each visit. Melasma and acne scars change slowly across a series.

How many pico laser sessions do I need?

It depends on what’s being treated. In tattoo trials, clearance above 70% took anywhere from 1 to 10 sessions. One acne scar study used six. Your clinician should give you a plan after assessing the area.

Are pico laser before and after photos real?

They should be. Look for the session count, interval, date and any combined treatments in the caption, with the same lighting and angle in both photos. Missing details are a reason to ask questions.

Is PicoSure better than other pico lasers?

PicoSure is one branded picosecond platform. What you end up with has more to do with the wavelength, the settings, who’s treating you and what’s being treated than the name on the machine, so if you’re comparing, look at published data and measured specs.

Can pico laser remove a tattoo completely?

Sometimes. Plenty fade a long way, and some clear fully, but dense, layered or very colorful ink often leaves a faint ghost behind, and an honest gallery will show you that.

Does melasma come back after pico laser?

It often does. The 1064 nm studies show it getting lighter, but stop the sunscreen and maintenance routine and it has a habit of creeping back.

Does pico laser work on acne scars?

With a fractional tip, yes, to a point. In the main study people saw a moderate change in texture after six sessions. Deep icepick scars respond least.

What is the downtime after pico laser?

Most people are pink and a bit puffy for anywhere from an afternoon to a few days, and if it was a tattoo, expect crusting or the odd blister that takes longer.

Conclusion

A trustworthy pico laser before and after photo carries its own context: sessions, intervals, timing, combined treatments, and what didn’t clear.

Lentigines and many tattoos show the clearest change. Melasma and acne scars move more slowly, and melasma often returns. For clinics, consistent photography and proper consent protect both the patient and the credibility of the gallery.
