It is broad-spectrum light.
IPL uses filtered pulses across a range of wavelengths, not a laser.
IPL: A broad-spectrum flashlamp, not a laser, used mainly for brown sun spots and facial redness. It is effective for those two problems on lighter skin, and it is not safe on deeper skin tones.
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.


Choose for sun spots and facial redness on lighter skin — it is not safe on deeper skin tones.
Choose for tattoo removal or sun spots — it works, but don't pay extra for the word "pico" alone.
Can you have both?
They can share a plan: IPL for redness and broad spots, picosecond for stubborn pigment. Space them about 4 weeks apart.
IPL uses filtered pulses across a range of wavelengths, not a laser.
It treats redness, benign pigmentation and unwanted hair.
A brown spot should be assessed before fading.
Tanning, darker skin and medicines raise the risk of burns or pigment change.
Picosecond lasers act on pigment or create fractional tissue effects.
Tattoos, pigmentation and texture each need different settings.
Spots should be confirmed before fading.
Cosmetic tattoos may darken; melasma needs careful selection.

Reduces redness and vessels.

Darkens spots that then flake off.

Fades most ink colors.

Clears small facial vessels.

Fades red marks.

Clears spots.

Focus lenses improve texture.

Doesn't change texture.

Doesn't target vessels.

Patches often rebound darker.

Pigment can rebound.
Face, neck, chest and hands.
The tattoo or diagnosed pigment spot determines the treatment site; location varies.
Filtered light enters skin: A range of wavelengths is selected for the treatment target. Pigment or blood absorbs energy: Melanin or hemoglobin converts absorbed light into heat. Selected targets fade: Healing can reduce the treated brown spots or visible vessels.

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.

4 weeks before: Sun and tanning: No sun, sunbeds or self-tanner.
2 weeks before: Hair removal: No waxing, threading or hair removal cream.
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.
3 to 5 days before: Actives and clean skin: Stop retinoids and exfoliating acids.
3 to 5 days before: Actives and shaving: Stop retinoids and exfoliating acids.
3 to 5 days before: Actives and shaving: Shave the area.
Clean skin: Clean, product-free skin.
Skin tone: A good provider will ask, and will decline if IPL is wrong for your skin.
Skin tone: Be direct about your skin tone and how easily you tan.
Skin is cleaned and examined, and the provider checks your skin tone and recent sun.
The tattoo or pigment is examined, photographed, and its colors noted, since they decide the wavelengths.
Opaque goggles go over your eyes and stay on; that is not optional.
The handpiece is pressed on the skin and fired in overlapping shots. You see a bright flash through closed eyelids. Each pulse feels like a hot rubber band snap, hottest over brown spots and hair, and stops as it ends. A full face takes about 20 minutes.
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.
Skin looks pink and feels warm, like mild sunburn.
The area is white and raised, then red and swollen as the frosting fades.
Days 1 to 2: Redness fades.
Days 1 to 3: Swelling peaks on day one or two and can be marked around the eyes, hands and ankles.
Days 3 to 14: Treated spots darken into fine brown flecks like coffee grounds, then flake away, leaving more even skin.
Days 3 to 14: Scabs form and fall away on their own, taking some ink with them.
Weeks 2 to 6: Vessels and background redness clear gradually, and keep improving over later sessions.
Weeks 2 to 8: Skin looks normal while the immune system clears ink fragments underneath.
1–2 weeks per session
Fading over weeks after each session
Months to years; new spots with sun
Removed ink is gone
In the US a full-face session usually runs about $300 to $600.
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 does not cover cosmetic pigment or redness treatment.
Insurance does not cover tattoo removal or cosmetic pigment treatment.
No. Broadband light is absorbed by all the pigment in its path, including the pigment that gives skin its color. On deeper skin tones that means burns and light or dark patches, and pale patches can be permanent. For pigment, ask about prescription creams and superficial peels. For hair, a 1064 nm Nd:YAG laser.
No. The skin tone chart supplied with home devices exists because the technology injures skin with more pigment, and most are labeled unsuitable for deeper skin tones and tanned skin. Many refuse to fire. The risk is the same as a clinic device, with nobody present to spot a problem early.
Usually not, and it commonly makes melasma worse: better for a few weeks, then darker and wider. If you have brown patches on the cheeks, forehead or upper lip, get a diagnosis before any light-based treatment.
That is what is meant to happen. Treated sun spots darken into fine brown flecks over the first few days, then flake off over one to two weeks. Do not scrub or pick.
Usually three to five for the face, three to four weeks apart, then maintenance once or twice a year. Brown spots improve faster than redness. Hair reduction takes six to ten or more.
No. IPL works on color: brown pigment and red vessels. Wrinkles, texture, pores and indented scars need a fractional laser or microneedling.
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.
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.
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.
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.
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.
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.
