Picosecond Laser
A tattoo and pigment laser that fires in pulses lasting trillionths of a second. It works, and the marketing around the word “pico” has run well ahead of the evidence comparing it to the older quality-switched lasers.
Key facts

Tattoos or selected pigment spots
Recovery
Swelling or blistering for days
Treatment plan
Often 5–10+ sessions, 6–8 weeks apart

About $200–500 per session
What is it?
It uses ultra-short pulses.
Picosecond lasers act on pigment or create fractional tissue effects.
It has several uses.
Tattoos, pigmentation and texture each need different settings.
Pigment needs a diagnosis.
Spots should be confirmed before fading.
Some pigments are tricky.
Cosmetic tattoos may darken; melasma needs careful selection.
What it treats
Unwanted Tattoos
Fades most ink colors.
Sun Spots
Clears spots.
Acne Scarring
Focus lenses improve texture.
Melasma
Pigment can rebound.
Spider Veins
Doesn't target vessels.
Treatment areas
Picosecond Laser
The tattoo or diagnosed pigment spot determines the treatment site; location varies.

Skin tones
Lighter skin
Low risk
Temporary whitening and swelling.
Medium skin
Some risk
Temporary lightening or darkening.
Deeper skin
Some risk
Lightening of skin can occur; longer wavelengths and spacing help.
How it works
Diagram explanation
Ultrashort pulses reach pigment: The wavelength and treatment mode are chosen for the target. Rapid energy delivery fragments pigment: Mechanical effects can break selected particles into smaller pieces. Clearance follows over time: The body clears some fragments; results depend on the pigment and skin.

Before your treatment
2–4 weeks before
4 weeks before: Sun and tanning: Avoid sun, sunbeds and self-tanner on the area.
4 weeks before: Sun and tanning: Tanned skin postpones a session — surface pigment competes for the light and raises the risk of burns and pigment loss.
Before you book: Numbing and history: Ask for numbing to be arranged in advance.
The week before
3 to 5 days before: Actives and shaving: Stop retinoids and exfoliating acids.
3 to 5 days before: Actives and shaving: Shave the area.
Day of treatment
Before you arrive
Clean skin: Clean, product-free skin.
Arrival & prep
The tattoo or pigment is examined, photographed, and its colors noted, since they decide the wavelengths.
Treatment
Everyone wears eye protection.
The provider fires overlapping pulses, with a snapping sound and a faint smell. Skin whitens at once — frosting — and fades within about 20 minutes. A small tattoo takes minutes; a large piece is split across appointments. It feels sharper than getting the tattoo but far quicker, and bony areas are worse.
Before you leave
The area is white and raised, then red and swollen as the frosting fades.
After your treatment
First 24 hours
Days 1 to 3: Swelling peaks on day one or two and can be marked around the eyes, hands and ankles.
Days 2–7
Days 3 to 14: Scabs form and fall away on their own, taking some ink with them.
Weeks 2–4
Weeks 2 to 8: Skin looks normal while the immune system clears ink fragments underneath.
Time to results
Fading over weeks after each session
How long results last
Removed ink is gone
Risks
Frosting, swelling, pinpoint bleeding, scabbing and a few days of soreness are expected, not complications. The real risks are pigment change, scarring, infection, and cosmetic ink turning dark.
Loss of pigment
A patch paler than the surrounding skin, in the shape of the tattoo. One of the commonest lasting outcomes, and slow or unable to recover. Conservative settings and longer gaps lower the risk.
Dark patches
Brown discoloration in the weeks after a session, more common on deeper skin tones and after sun. Usually fades over months, faster if treated early.
A tattoo that got darker
White, flesh-toned and pastel cosmetic inks can turn gray or black on contact with the laser. Sometimes further treatment clears it, sometimes not, which is why a test spot comes first.
Blisters that keep forming
Some blistering is common. Repeated or large blisters mean lowering the settings.
A raised or thickened area
Scarring and keloids are uncommon but real, and more likely with picking, infection or aggressive settings. Report it early.
Itching, swelling or hives in the tattoo
An allergic reaction to ink released into the body. Uncommon, occasionally systemic, worth reporting the same day.
Cost
Typical cost
About $200–500 per session
Pricing
In the US, a picosecond session on a small to medium tattoo commonly runs $200 to $500, with larger pieces priced higher and often split into sections.
Insurance
Insurance does not cover tattoo removal or cosmetic pigment treatment.
Alternatives
Quality-switched (nanosecond) lasers
And decades of use. The established comparison, and still widely used. Often cheaper per session and may need more sessions. Direct head-to-head trials against picosecond devices are limited and their results are mixed, so the honest position is that both clear tattoos and the size of any difference is unsettled.
Surgical excision
The only method that removes ink completely and predictably. Limited to small tattoos, and it trades the tattoo for a surgical scar. Sometimes used for a small stubborn remnant at the end of a laser course.
Fractional ablative resurfacing
For scars and texture, limited for ink. A different job — it resurfaces skin rather than shattering pigment — with more downtime and more caution needed on deeper skin tones.
Microneedling
For acne scars and texture, with or without radiofrequency. Cheaper per session, no wavelength to match, and does nothing at all for tattoo ink. Often chosen over fractional laser modes on deeper skin tones.
Topical pigment treatment
For melasma and sun spots. Hydroquinone, azelaic acid, tranexamic acid and retinoids work slowly, cost far less, and carry no risk of a burn. For melasma in particular they are the foundation, with laser as an addition rather than a replacement.
A cover-up tattoo
No medical evidence involved, but a real option. Faster and cheaper than a full removal course, and a few laser sessions to lighten the original first usually give the artist far more to work with.
Daily broad-spectrum sunscreen
The single most useful thing you can do between sessions. Sun on treated skin causes dark patches and gets appointments postponed, and it undoes pigment treatment faster than the laser improves it.
Prescription pigment creams
Hydroquinone, azelaic acid, tranexamic acid and topical retinoids treat brown patches and melasma at home, and do a large share of the work in any melasma plan. They have no effect on tattoo ink.
Plain healing ointment and a dressing
This is the entire aftercare routine for a treated tattoo. Keep it covered, keep it moist, do not pick.
Makeup and tattoo cover creams
High-pigment camouflage makeup covers a tattoo well for a day. It changes nothing underneath, and it is honest to say so.
Questions
Is a picosecond laser better than an older Q-switched laser?
Not settled. Studies generally find picosecond devices perform at least as well, and some report clearance in fewer sessions, but the head-to-head trials are few, small and inconsistent. “Pico” is a marketing category, not a standard, so devices differ a lot. The provider's experience and the wavelengths available for your ink colors matter more than the category name.
How many sessions will my tattoo take?
Most professional tattoos need five to ten or more, six to eight weeks apart, so a year or longer. Amateur tattoos need fewer, cover-ups more. Nobody can give an accurate number at the first visit; how the first two sessions go is the best predictor available.
Will my tattoo disappear completely?
Sometimes, but heavily faded with a faint shadow is more common. Ink type, depth, color, age and location all matter, and none can be judged from the surface beforehand. Treat a guarantee of complete removal as a warning sign.
Which colors are hardest?
Black and dark blue clear most readily. Green and light blue are hardest and need specific wavelengths. Red, orange and yellow are unpredictable. White, flesh-toned and pastel cosmetic inks can turn dark instantly, which is why they get a test spot first.
Can it be used on deeper skin tones?
Yes, generally at 1064 nm, because surface pigment absorbs it least — the same reason the Nd:YAG laser is preferred there for hair and vessels. Multicolored tattoos are harder, because the wavelengths needed for some colors carry more risk of a light or dark patch. Conservative settings, test spots and longer gaps are standard.
Does it help melasma?
Sometimes, with mixed results. Melasma often improves during a course and then returns, and heat and light can provoke it. Most dermatologists lead with sun protection and pigment creams and add laser cautiously.
