Pico or IPL for pigmentation
Both are very good at what they do, and they do different things. The mistake is choosing between them before anyone has worked out what kind of pigment you actually have, because that is the decision that matters.
First, pigment is not one thing
People arrive asking for a laser. What they usually need first is a diagnosis, because several quite different conditions look similar in a bathroom mirror and respond very differently to light.
- Sun damage. Flat brown marks from years of accumulated exposure, sitting mostly in the upper layers of the skin.
- Freckling. Genetic, darkens with sun, generally superficial.
- Melasma. Larger, softer-edged patches, often symmetrical, strongly influenced by hormones and heat. It behaves differently from everything else on this list.
- Post-inflammatory pigmentation. Marks left behind after acne, injury or an over-aggressive treatment.
- Redness and vessels. Not pigment at all, though it often sits alongside it and needs treating too.
Sun damage and melasma can look alike and are treated almost oppositely. That is the single most useful thing on this page.
What each device actually does
IPL
Intense pulsed light is a broadband light source rather than a laser. It works by heat, and it is absorbed both by pigment and by the haemoglobin in small blood vessels. That dual action is its real strength: it can address brown sun damage and background redness in the same treatment, which nothing else on the menu does as neatly.
It is excellent for superficial sun damage and freckling on fair skin, particularly across the face, chest and hands.
Pico
A picosecond laser delivers energy in pulses so short that the effect is closer to a shockwave than to heating. Pigment is broken apart mechanically, with comparatively little heat spreading into the surrounding skin.
That matters for two reasons. It reaches pigment sitting deeper in the skin, and because it produces less heat it is generally the safer choice in darker skin tones and in anyone prone to pigmenting after inflammation.
Side by side
| IPL | Pico | |
|---|---|---|
| Type | Broadband light, not a laser | Picosecond laser |
| How it works | Heat, absorbed by pigment and blood vessels | Very short pulses that fragment pigment mechanically |
| Best for | Superficial sun damage, freckling, redness and vessels together | Deeper or stubborn pigment, darker skin tones, some tattoo pigment |
| Treats redness | Yes, which is its distinguishing feature | No |
| Skin tone suitability | Best in fairer, untanned skin | Broader range, including deeper tones |
| Typical recovery | Redness, then marks darken and flake over roughly one to two weeks | Usually milder, often redness settling within a day or two |
Melasma deserves its own paragraph
Melasma is the most common reason a pigmentation plan goes backwards. It is chronic, it relapses, and it is provoked by heat and light as much as by sun exposure. Treating it as though it were sun damage, with enthusiastic light-based treatment, can leave the skin worse than it started.
It can be managed well. It is managed with a slower, layered approach, careful photoprotection, and often topical and oral treatment doing much of the work, with any device used cautiously and at conservative settings. If someone offers to clear melasma in a couple of sessions, be sceptical.
When neither is the right next step
- Any pigmented spot that is changing. New, growing, altering in colour or shape, or simply different from the others. That needs looking at properly before any device goes near it, and that is not a cosmetic question.
- Before sun protection is sorted. Treating pigment without daily protection is refilling a bath with the plug out.
- Recently tanned skin. Timing matters, and waiting is usually the better clinical decision.
- Active inflammation. Settle the acne or the dermatitis first, or you are treating a moving target.
- When the real concern is texture or laxity. Pigment is often what people notice, but not always what is actually bothering them.
The part that decides your result
Neither machine chooses its own settings. Wavelength, energy, pulse duration, how many passes, what season it is, what your skin has been exposed to recently, and above all what the pigment actually is, are all judgements made by the person treating you.
This is a field where the same device produces genuinely different outcomes in different hands, and where the most costly mistake is not choosing the wrong machine but treating the wrong diagnosis confidently. Good pigment work tends to look unremarkable and gradual, and that is the point.
Common questions
Which is better for sun damage?
For superficial sun damage on fairer skin, IPL is often the more efficient choice, particularly if there is redness to address at the same time. Deeper or more stubborn pigment usually suits Pico better.
Will either of these fix my melasma?
Neither clears melasma permanently, and aggressive light-based treatment can make it worse. It is managed rather than cured, usually with topical treatment and careful photoprotection doing most of the work.
Is Pico safer for darker skin?
Generally yes. It produces less heat, so there is less risk of pigmentation afterwards. It still needs appropriate settings, which is a matter of experience rather than a property of the machine.
How many sessions will I need?
It depends on the type and depth of pigment. Superficial sun damage often responds in a small number of sessions. Deeper or mixed pigmentation takes longer, and melasma is ongoing management rather than a course.
Can I have treatment in summer?
It is usually better to treat outside peak sun months, and essential that skin is not recently tanned. Timing is part of the plan rather than an inconvenience.
Will the pigment come back?
Some will, particularly with sun exposure or hormonal drivers. Daily protection does more to hold a result than any device does to create one.
Does it hurt?
Both are tolerable. IPL is often described as a hot elastic band snap, Pico as a lighter prickling. Neither routinely needs more than surface numbing.
I have a spot I am worried about, can you just remove it?
Not before it is assessed. Any pigmented lesion that is new or changing needs a proper look first, because treating it with light could remove the evidence rather than the problem.
Working out which kind of pigment you have is the appointment. The device follows from that.
All medical procedures carry risk, and individual results vary. Suitability is determined at assessment.
