Almost every practice sells IPL for both. It does treat both — that's exactly the problem, and it's why we moved pigment onto a different device.
IPL is filtered broad-spectrum light, not a laser. It's absorbed by both haemoglobin and melanin, which is why it can treat redness and pigment — and why it carries burn and pigmentation risk above Fitzpatrick III. At Plump it's used for diffuse redness, flushing, and rosacea-associated erythema. Brown pigment is treated with picosecond laser instead.
The standard pitch is that IPL is versatile: one device, sun spots and redness together, done. That's accurate as far as it goes.
Broad-spectrum light contains many wavelengths at once. Some are absorbed by haemoglobin — that treats redness. Some are absorbed by melanin — that treats brown spots.
Energy goes into blood. Melanin absorption is incidental. Manageable in appropriate skin types.
Energy goes into melanin — all of it, including the melanin in normal surrounding skin.
That second case is where it goes wrong. The device can't distinguish the melanin in a sun spot from the melanin in the epidermis around it. In skin with more baseline pigment — or skin that's simply tanned — the energy is absorbed across the whole area rather than only by the target.
The result is burns, blistering, and post-inflammatory hyperpigmentation — darkening caused by the treatment meant to remove darkening.
Picosecond laser doesn't have this problem. It fragments pigment mechanically using ultra-short pulses, depositing very little heat, and is appropriate across a far broader range of skin tones.
So we use each device for what it does uniquely well. Pico can't treat diffuse redness. IPL can. That's IPL's job here.
The pattern: IPL for colour spread across an area. A laser for anything discrete. And picosecond for anything brown.
This distinction does most of the work. If you can point at a single vessel, that's a job for a targeted laser — Nd:YAG delivers energy into that vessel specifically.
If the redness is a wash of colour across the cheeks with no individual vessel to aim at, that's IPL. Scattering broad-spectrum light across a region is exactly what it's built for.
Plenty of patients have both, and get both.
Tanned skin. A tan is additional epidermal melanin, which means more absorption where you don't want it. IPL on tanned skin is a burn risk regardless of your usual Fitzpatrick type. This isn't caution — it's the most common cause of IPL complications, and it's why treatment is deferred rather than performed on recently sun-exposed skin.
Fitzpatrick IV and above. IPL is generally appropriate for types I to III. Higher than that, melanin absorption becomes the dominant effect and safer options exist. See device selection by skin tone.
Most patients booking IPL for redness have rosacea, whether or not it's been named.
IPL treats the vascular component well — the background colour, the visible surface vessels, some of the flushing. That's a real improvement and it's often significant.
It does not treat rosacea. Rosacea is an inflammatory condition with triggers, flares, and a medical management side that light can't address. Papules and pustules need medical treatment. Flares will still happen.
The honest framing: IPL manages the visible redness, and results are maintained rather than permanent, because the underlying tendency doesn't go away. Patients who understand that are consistently happier than those told it's a cure.
More than with most treatments. IPL works by absorption into pigment, so the less baseline pigment in the skin, the safer and more effective it is.
That means avoiding sun exposure and self-tanner for two weeks before, and protecting rigorously afterward. In coastal Orange County that's a real constraint — and patients who can't commit to it are usually better served by a different device.
Moving pigment off IPL entirely was a deliberate decision. IPL for brown spots works well in fair, untanned skin and produces the worst complications I see in everything else — and in this part of California, a lot of patients are tanned without thinking of themselves that way. Pico does the same job with a fraction of the risk. IPL still earns its place for redness, which Pico can't touch.
What does IPL treat?
At Plump Medical Spa, IPL is used for diffuse facial redness, flushing, background erythema associated with rosacea, and generalised vascular colour across an area. It is not used for brown pigment. Sun spots, melasma, and post-acne marks are treated with picosecond laser instead, which carries lower risk of worsening pigmentation.
Why don't you use IPL for brown spots?
Because IPL is absorbed by melanin as well as by haemoglobin. That dual absorption is what allows it to treat both pigment and redness — and it is also the source of its main risk. In skin with more melanin, or skin that is tanned, the light is absorbed throughout the epidermis rather than only by the target, which can cause burns, blistering, and post-inflammatory hyperpigmentation. Picosecond laser fragments pigment photoacoustically with far less heat, which makes it both safer and more precise for pigment.
Is IPL safe for darker skin tones?
IPL is generally appropriate for Fitzpatrick I to III. Above that, melanin absorption becomes a meaningful risk and other devices are more appropriate. It should also not be performed on tanned or recently sun-exposed skin at any Fitzpatrick type, since tanning increases epidermal melanin and therefore the risk of a burn.
Does IPL help rosacea?
It helps the vascular component — the background redness, flushing, and visible surface vessels. It does not treat rosacea as a condition and does not prevent flares, which are managed medically. Patients with rosacea usually need both: light-based treatment for the visible redness and a medical plan for the underlying inflammation.
What is the difference between IPL and laser?
IPL is not a laser. It emits filtered broad-spectrum light across a range of wavelengths, which is absorbed by multiple targets at once. A laser emits a single wavelength selected for a specific target. That makes IPL well suited to treating diffuse colour across an area, and lasers better suited to treating a specific structure precisely.
IPL or Nd:YAG for facial veins?
IPL is better for diffuse background redness spread across an area. Nd:YAG is better for discrete visible vessels — an individual spider vein or broken capillary — because energy is delivered into that vessel rather than scattered across the region. Many patients have both problems and benefit from both treatments.
How many IPL sessions are needed?
Typically three to five sessions spaced three to four weeks apart, with periodic maintenance afterward. Redness is a chronic tendency rather than a one-time problem, so results are maintained rather than permanent.
What is the downtime after IPL?
Minimal. Mild redness and warmth for a few hours, occasionally into the following day. Makeup can generally be worn the same day once the skin feels calm. Sun protection afterward is essential.
If you're not sure which you have — and plenty of patients have both — that's what the consultation sorts out.
