IPL, or Intense Pulsed Light, is often grouped alongside gentle, non-ablative laser treatments, but in clinical dermatology it occupies a distinct and valuable role. Used appropriately, it can address a range of vascular and pigment-related skin concerns with precision, while maintaining a relatively gentle profile compared to more aggressive modalities.
At Dr Haus Dermatology in Harley Street London, we view IPL not as a cosmetic “quick fix”, but as a versatile medical tool with an important role in both dermatology and regenerative skin medicine. Its effectiveness depends on accurate diagnosis, personalised treatment planning, and the experience of the practitioner delivering it. Every IPL treatment is tailored to the individual, taking into account factors such as skin type, the underlying skin condition, and treatment goals rather than following a one-size-fits-all approach.
What is IPL (Intense Pulsed Light) and how does it work?
IPL is a light-based treatment that delivers broad-spectrum wavelengths into the skin. Unlike a single-wavelength laser, IPL emits multiple wavelengths, allowing it to target different chromophores such as haemoglobin and melanin.
Put simply, it works by:
Because of this mechanism, IPL is particularly effective for concerns involving redness, visible vessels, and pigmentation irregularities. It is commonly used to help manage conditions such as rosacea, acne-related redness, post-inflammatory hyperpigmentation (PIH), sun damage, and diffuse facial flushing.
A common misconception is that IPL is interchangeable with laser therapy. In reality, the lasers we use in the clinic are often more targeted and intense, whereas IPL offers broader coverage with a slightly softer approach. The choice between them depends on the condition being treated and how the skin is behaving.
IPL is useful for conditions involving redness or pigmentation.
In the clinic we often see patients with persistent background redness or flushing that has not responded well to topical treatments. IPL can help reduce the inflammation to address:
For milder cases of rosacea, we would usually start with skincare and medical management. If that is not settling, IPL becomes a very effective next step, particularly for vascular components.
IPL can target areas of excess melanin, making it useful for:
For more stubborn cases, IPL can be combined with treatments such as Chemical Peels, which help accelerate skin turnover and improve overall clarity.
Small visible vessels, particularly around the nose and cheeks, respond well to IPL. The light energy is absorbed by haemoglobin, causing the vessels to collapse and gradually fade.
While IPL is not a primary acne treatment, it can be helpful for post-inflammatory redness. For active acne, we are more likely to use targeted approaches and then introduce IPL later to address residual redness.
IPL is highly effective, but it is not always the first or best option.
In practice, treatment planning is about combining approaches to address different layers and mechanisms within the skin.
IPL is generally well tolerated, with minimal downtime.
Most patients require a course of treatments rather than a single session. We usually recommend a series spaced a few weeks apart, followed by maintenance if needed.
At our Harley Street clinic in London, IPL is always delivered as part of a broader dermatology-led plan.
We start with a detailed consultation to assess:
From there, we determine whether IPL is appropriate or whether another treatment would deliver better results.
In some cases, IPL is the primary treatment. In others, it forms part of a staged approach alongside options such as Laser Treatments, Chemical Peels, or Medical-Grade Skincare.
The key difference is that treatment is guided by diagnosis, not just availability.
No. IPL uses a broad spectrum of light, while lasers use a single wavelength. Lasers are more targeted, whereas IPL is more versatile for generalised concerns.
Most patients require a course of 5 to 6 sessions, depending on the condition being treated.
It is generally well tolerated. Most patients describe it as mildly uncomfortable rather than painful.
A common misconception is that IPL is only suitable for lighter skin tones. At Dr Haus Dermatology, we have extensive experience treating Fitzpatrick skin types 1–6. Different skin types respond differently to light-based treatments, which is why treatment settings are carefully tailored to the individual. Careful diagnosis, practitioner expertise, and a personalised treatment plan are essential to achieving safe and effective results rather than taking a one-size-fits-all approach.
It can significantly reduce these concerns, but maintenance is essential, particularly for conditions like rosacea.
IPL can be an extremely effective treatment when used correctly, but its success depends on careful diagnosis and clinical expertise.
If you are considering IPL, the most important step is to book a consultation to determine whether it is the right option for your skin, or whether a different or combined approach would deliver better results.
At our Harley Street clinic, we take a measured, dermatology-led approach to ensure treatments are both safe and effective.
