LUMECCA IPL treatment, Southam, Warwickshire
If you are struggling with uneven skin tone, sunspots or general pigmentation, IPL can feel like a tempting solution. It is one of the most commonly used light-based treatments in aesthetic medicine and for good reason. When it is used correctly, IPL can significantly improve pigmentation, brighten the complexion and smooth the overall appearance of the skin. But one of the first questions patients ask me is always the same. How many sessions do I actually need to see a real difference?
The answer depends on several factors including your skin type, the type of pigmentation you have and how your skin responds to treatment. In this blog, I break down how IPL works, what influences the number of sessions required and what you can realistically expect from a full course.
What is IPL and how does it work?

IPL stands for Intense Pulsed Light. It is not a laser, but a broad-spectrum light treatment that targets pigment in the skin. The light is absorbed by melanin, which is the pigment responsible for sunspots, freckles, and uneven tone. Once absorbed, the light heats the pigment and breaks it down so that the skin can naturally clear it over the following days and weeks.
Unlike lasers, IPL can treat multiple issues at once because it uses a range of wavelengths. This means it can target pigmentation, redness, and general skin dullness in a single session. It also stimulates a mild collagen response, giving the skin a fresher, smoother appearance over time.
How many IPL sessions are needed for pigmentation?
Most patients need a course of three to six sessions to see the best results for pigmentation. For some, especially those with lighter sunspots or more superficial pigmentation, improvements can be seen after just one or two sessions. However, pigmentation that is deeper or more widespread usually requires a fuller course.
Treatments are typically spaced three to four weeks apart. This allows the skin to heal, the pigmentation to rise to the surface and the new pigmentation to be assessed before the next session.
It is important to understand that pigmentation is not always a one-time fix. While IPL can significantly reduce it, new pigmentation can form over time through sun exposure, hormones or inflammation. Many patients choose a yearly maintenance treatment to keep their results stable.

Every skin is different. These are the biggest factors that influence how many IPL treatments you will need.
The depth of pigmentation
Superficial pigmentation such as sunspots and freckles responds very quickly. Deeper pigmentation created by years of sun exposure or post inflammatory pigmentation often requires more sessions.
Your natural skin tone
IPL is safest and most effective on fair to medium skin tones. It can be used in some darker skin tones, but only with great caution and at low settings. In these cases, more sessions may be needed to avoid overstimulating the skin.
Hormonal pigmentation
Conditions like melasma are far more complex to treat. IPL is not the preferred treatment for active melasma because it can trigger rebound pigmentation. In these cases, medical skincare, chemical peels, polynucleotides or other modalities are usually safer and more effective alternatives.
Your lifestyle and sun exposure
If you have a lot of ongoing sun exposure, pigmentation will continue to reappear. Consistent sunscreen use is essential for long lasting results.
What results to expect after each session

You might notice some initial darkening of the treated pigmentation one to three days after your session. This is normal and expected. The pigment rises to the surface before shedding or flaking away. Most patients notice a clearer and brighter complexion within one to two weeks.
With each session, the intensity and number of dark patches gradually reduces. By the end of your course, skin tone is more even, sun damage is significantly lighter and the skin looks fresher overall.
What IPL does not treat well
It is important to address common misconceptions. IPL does not reliably treat melasma, hormonal pigmentation or pigmentation caused by deeper structural changes. These concerns often need a combination of skincare, peels or regenerative treatments rather than light-based therapy.
A clinical assessment is vital so that we can identify exactly what type of pigmentation you have before choosing the right treatment.
