Intense pulsed light, or IPL, has become one of the most popular treatments for evening out and refreshing the skin. It is non-invasive and can tackle several concerns in one session. The rise of cheaper professional treatments and at-home devices has only added to the buzz. Whilst appealing, IPL is not a laser, it does not suit every skin tone and the results are not permanent. In this article, we explore what IPL actually does, who it suits, risks, how it compares with laser and where good skincare fits alongside it.
Please note, we are an online skin clinic so we do not offer IPL or any in-clinic light treatments. We have written this article because we believe people deserve clear, honest information about all of their options.
What is IPL and How Does it Work?
IPL uses short, high-intensity pulses of broad-spectrum light to rejuvenate the skin. The light is absorbed by pigments in the skin and converted into heat. The main targets are the melanin in dark spots and the haemoglobin in small blood vessels. That heat breaks down unwanted pigment and warms the deeper layers, which prompts the skin to make new collagen. DermNet describes IPL as a form of photorejuvenation that can treat several concerns at once.
Here is the single most important thing to understand. IPL is not a laser. A laser emits one precise wavelength of light, whilst IPL releases many wavelengths across a broad band. That difference runs through everything else. It shapes which concerns each treats best and how they behave on different skin tones.
What Can IPL Treat?
Because it covers a broad band of light, IPL can address several concerns at once. It works best for:
- Dark spots and sun damage: IPL can noticeably fade hyperpigmentation such as sun spots and freckles, lifting overall tone.
- Redness and visible vessels: the light targets haemoglobin, so it helps with facial redness, thread veins and the flushing of rosacea.
- Texture and early ageing: by nudging collagen production, IPL can soften fine lines and improve mild acne scars, for a smoother and brighter complexion.
Who is IPL Best For?
IPL is not equally safe or effective on every skin tone. This is where many people come unstuck. Because the light is drawn to melanin, it works most predictably when the target stands out clearly from the surrounding skin. Think a brown spot or a small vessel against paler skin.
That makes IPL safest and most effective on lighter to medium skin, around Fitzpatrick types I to III. On deeper skin tones (types IV to VI), the surrounding skin holds more melanin, so it can absorb the light too. This raises the risk of burns, along with hyperpigmentation or patches of lightening. Some newer devices have lower-energy settings intended for darker skin. Even so, the safety margin is narrower and the results less reliable. If your skin is deeper in tone, a longer-wavelength laser such as the Nd:YAG is often the safer light-based option. For pigment specifically, prescription skincare is frequently the lowest-risk route of all.
What Does IPL Treatment Involve?
A course of IPL usually starts with a consultation and often a patch test. This lets the practitioner check your skin type and confirm that IPL is suitable. You will normally be asked to pause active ingredients such as Retinoids. Avoiding the sun for a few weeks beforehand also helps.
On the day, you wear eye protection and the practitioner applies a cooling gel for comfort. They set the device to your skin type and concern. Then they move the hand piece across the area in pulses of light. Afterwards they apply a soothing gel and give aftercare advice. The treated skin often looks pink and feels like mild sunburn for a day or two. Diligent moisturising and daily sun protection are essential whilst it settles.
How Many Sessions Will You Need?
IPL is a course, not a one-off. Most people need between 3 and 6 sessions to see the best results. These are usually spaced 4 to 6 weeks apart, so the skin can recover and respond. More stubborn hyperpigmentation or extensive sun damage can need more, whilst minor concerns may need fewer. Many clinics then suggest a maintenance session once or twice a year to keep results topped up.
Are the Results Permanent?
IPL has a good track record for skin rejuvenation. Some studies report success rates of up to 80% for hyperpigmentation, vascular marks and texture. The improvements are real, but they are not permanent. Your skin keeps ageing and the sun keeps causing new damage, so fresh pigment and vessels can appear over time. Daily sunscreen and a good skincare routine do most of the work of making a result last.
What are the Risks?
IPL is generally safe in trained hands, but it is not risk-free. The common effects are mild redness and swelling that settle within hours to a couple of days. Some people also notice a sunburn-like warmth and light peeling. Less often, IPL can cause blistering, bruising or changes in skin colour. This usually happens when the device is set wrong for the skin type or aftercare is poor. There is also a real risk of eye injury without proper protection. The best safeguard is the person holding the device. The NHS advises checking that whoever treats you is suitably qualified and experienced. They should also assess your skin type before treating it.
How Much Does IPL Cost?
Cost varies with location, the practitioner’s expertise and the size of the area. In the UK, a single IPL session typically runs from £200 to £500. A recommended course usually totals between £600 and £1,500. It can be more for larger areas or extra sessions. Watch for the extras too, such as consultation fees, aftercare products and follow-up visits. Some clinics include these and others charge separately.
What’s the Difference Between IPL and Laser?
IPL and laser are often confused, but they are not the same. The distinction matters when you are choosing. The main differences are:
- The light itself: IPL uses a broad spectrum of wavelengths, whilst a laser uses a single focused one. IPL is the generalist, treating several mild concerns at once. A laser is the specialist, better for precise or stubborn targets.
- Skin tone: IPL suits lighter to medium skin best. Lasers cover a wider range, including specific devices that treat deeper skin tones more safely.
- Recovery: both can be low-downtime. Ablative resurfacing lasers can need a week or more, whereas IPL rarely needs more than a day.
- Cost: IPL is usually cheaper per session, partly because it can cover several concerns at once.
For most stubborn or deep concerns a laser wins. For broad, mild hyperpigmentation and redness on fair skin, IPL is often the more sensible choice.
IPL at Home or in Clinic?
At-home IPL devices promise the same idea at a fraction of the price. For the right person, they can help. Clinic treatments use powerful machines that a trained practitioner tailors to your skin. They tend to work faster, go further and carry a higher margin of safety. Home devices run at much lower energy to stay safe for unsupervised use. That makes them gentler, but also slower and more limited. If you have a pre-existing skin condition, are prone to hyperpigmentation or have a deeper skin tone, see a professional before trying either.
Where About Skincare?
Whether or not you ever try IPL, prescription skincare does much of the same work with far less risk. It also protects any IPL result afterwards. For hyperpigmentation and melasma, the most effective topical actives are things like tretinoin, hydroquinone, azelaic acid and tranexamic acid. They fade existing marks and slow new ones without any heat. For the redness and flushing that draw people to IPL, topical rosacea treatment with metronidazole, ivermectin and azelaic acid is well established. For texture and early ageing, Retinoids rebuild collagen over time and niacinamide supports the barrier. A good vitamin C adds antioxidant protection against fresh sun damage. Where you want a professional step beyond creams, chemical peels and radiofrequency microneedling sit alongside light treatments as options worth weighing. Whatever you use, daily sunscreen is the one active none of the others can replace.
IPL can be a genuinely useful treatment for the right skin and the right concern, particularly broad hyperpigmentation and redness on fairer skin. It is not a laser, not suitable for everyone and not permanent. So it pays to understand what you are buying and who is delivering it. For a great many people, consistent prescription skincare achieves much of the same result more safely. It also makes any in-clinic treatment last longer. As ever, the best first step is honest advice from a qualified professional.
At City Skin Clinic, we don’t provide IPL or any in-clinic light treatments. We do however offer personalised prescription skincare for hyperpigmentation, melasma, rosacea and skin ageing using ingredients like tretinoin, hydroquinone, azelaic acid and tranexamic acid where appropriate.
