IPL hair removal: Everything you need to know about permanent IPL treatment
Why IPL is currently the most popular hair removal method
In 2025, millions of people in Germany still spend valuable time every week shaving, waxing, or epilating - often with painful or merely short-term results. This is exactly where IPL hair removal comes in, having become the preferred solution for permanently achieving smooth skin within just a few years. According to current analyses, the German market for intense pulsed light devices is growing by more than 12% annually as more and more consumers recognize the benefits of permanent hair reduction. The technology has been established in medical dermatology for over 25 years and is used millions of times worldwide. Studies show that after a complete course of 6–12 treatments, up to 90% of the hair can remain permanently removed - a result that no other non-invasive method achieves as reliably. Many people ask: Why now? Quite simply, the devices are safer, more affordable, and easier to use than ever before. Professional treatments in studios remain in demand, but more and more people are using high-quality home devices and achieving excellent results. The trend is clearly moving toward “less is more”: Instead of shaving daily or booking a monthly waxing appointment, after the initial phase, usually just one or two maintenance treatments per year are needed. This not only saves time but also a great deal of money in the long term.What is IPL? The basics of the technology
Intense Pulsed Light (IPL) is a light-based technology that uses a broad wavelength spectrum between approximately 500 and 1200 nanometers. Unlike lasers, which emit only a single, precisely defined wavelength, IPL uses polychromatic light and can therefore target various structures in the skin simultaneously. The central mechanism of action is called selective photothermolysis: The light is preferentially absorbed by the dark pigment melanin in the hair, converted into heat, and thereby destroys the hair follicle without permanently damaging the surrounding skin. Clinical studies demonstrate an average hair reduction of 70–90% after a complete treatment series. Important to know: IPL is not a laser, but a distinct technology. It is generally gentler and more versatile because different filters can adapt the spectrum to the respective skin and hair type. This is why IPL is also highly suitable for additional applications such as acne treatment, lightening pigmentation spots, or skin rejuvenation. In Germany, both professional and home-use devices are subject to strict safety requirements under the EU Medical Device Regulation (MDR). Modern devices feature skin sensors and automatic energy selection, making use even safer and easier.
This is how a professional or at-home IPL treatment works
The process of an IPL session is always the same – whether in a studio or at home:
- Thoroughly cleaning the skin and shaving the area (no waxing or plucking in the weeks beforehand!)
- Applying a special contact gel
- Adjusting the energy according to skin and hair type
- Delivering the light pulses in overlapping passes
- Removing the gel and applying a soothing product
The contact gel is not only a coolant; it also ensures better light transmission and reduces the surface temperature by up to 10 °C – a crucial safety factor.
The actual treatment takes between 10 and 40 minutes, depending on the area. Mild redness may occur immediately afterward, usually subsiding within a few hours. The treated hairs do not fall out immediately, but are gradually shed over the following 1–3 weeks – a completely normal and desirable sign that the follicles have been damaged.
In professional practices, the “In-Motion” technique is frequently used: The handpiece glides continuously over the skin while delivering many low-energy pulses. This method is particularly gentle and enables more even heating of the follicles while reducing the risk of overheating the epidermis. Studies show that the In-Motion technique can reduce pain sensation by up to 60% without compromising effectiveness.
Home devices generally use the classic “stamp” method (individual pulses with light pressure). Modern devices such as the Philips Lumea Prestige or Braun Silk-expert Pro 5 automatically measure the skin type and adjust the energy every second - a safety feature that virtually eliminates the risk of burns.
To be completely honest: The biggest difference between professional salons and home use today is no longer the technology, but the energy level and treatment area coverage. Professional devices use a significantly higher number of joules and therefore finish a little faster, but the results with consistent home use are now almost identical.
Consistent sun protection (SPF 50+) is essential during the first few weeks after treatment because the skin is more sensitive to light. There should be 4-6 weeks between sessions so that the hairs are in their next growth phase. Only about 20-30% of all hairs are in the anagen phase at the same time - this is precisely the phase in which IPL is most effective.
The major advantages of IPL technology
Permanent hair reduction is the most obvious benefit: After a course of usually 6-12 treatments, up to 90% of the hair remains permanently gone. This means not only smooth skin, but also the end of razor burn, ingrown hairs, and constant waxing appointments.
Compared with laser treatments, IPL is generally significantly more affordable and faster - especially for large areas such as the legs or back. At the same time, the treatment is virtually painless: Most people feel only a warm tingling sensation or a light snap like a rubber band.
Another major advantage: IPL is a true multitasking technology. In addition to hair removal, it successfully treats acne, rosacea, pigmentation spots, and small blood vessels - often in the same session. This makes it particularly attractive for beauty salons and dermatologists.
IPL has also advanced significantly for home use in recent years. Modern devices from Philips, Braun, or Silk’n are so safe and easy to use that millions of people now successfully treat themselves at home.
Which body areas and skin concerns is IPL suitable for?
The classic areas are the legs, armpits, arms, back, chest, and the entire bikini and intimate area. In the intimate area in particular, many people appreciate the significantly lower tendency toward ingrown hairs and skin irritation compared with shaving or waxing.
The face (upper lip, chin, cheeks, sideburns) can also be treated very effectively - but with lower energy because the skin is more sensitive. In recent years, IPL has become the treatment of choice for women with hormonally induced facial hair.
In addition to simple hair removal, IPL is excellently suited for treating acne, pigmentation and age spots, spider veins, and general skin rejuvenation by stimulating collagen production. Many studios therefore offer combination treatments.
For Fitzpatrick skin types I-IV (fair to Mediterranean), IPL is almost always possible without problems. With types V-VI, it becomes critical and should only be performed by experienced dermatologists.
Which products are really needed for optimal and safe results?
The success of an IPL treatment depends crucially on the quality of the aids used. By far the most important product is a high-quality contact gel that performs several tasks at once: it cools the skin, improves light transmission, and prevents superficial burns. Cheap gels from drugstores often contain alcohol or fragrances and can irritate the skin. Professional contact gels such as Epi-Med are pH skin-neutral (5.5-6.5), free from parabens, colorants, and fragrances, and have exactly the right viscosity to remain in place throughout the treatment. They are used both in beauty institutes and by discerning private customers. Beginners are advised to choose a complete starter set containing everything they need: safety glasses, a razor, cooling pads, and, of course, the right gel. Anyone who already owns an IPL device is best off choosing larger quantities - this saves a lot of money in the long run.

Risks, side effects, and how to avoid them
As with any light treatment, slight redness, swelling, or a feeling of warmth may occur - this is normal and usually subsides within a few hours. In rare cases, incorrect use can cause blisters or pigmentation changes, especially on freshly tanned or very dark skin. Therefore: Always perform a patch test, start with low energy, and avoid intense sun exposure for at least four weeks before and after treatment. Pregnant or breastfeeding women and people with active skin conditions should avoid IPL. Anyone who follows these rules and uses high-quality products can reduce the risk practically to zero. Dermatologists repeatedly emphasize that, when used correctly, IPL is one of the safest methods of permanent hair removal.FAQ - The 7 most important questions about IPL hair removal
Is IPL really permanent?
Yes - after a complete course of 6–12 treatments, 80–90% of the hair remains permanently removed in most people. Long-term dermatological studies spanning 10 years show that hair reduction remains at 70–85% even after a decade. This does not mean absolute hairlessness for everyone, because hormonal changes (pregnancy, menopause, PCOS, thyroid medication) can activate new follicles. In such cases, 1–2 maintenance treatments per year are usually enough to restore the result to 90%.
Does IPL treatment hurt?
Pain perception varies from person to person, but is significantly lower than with waxing or needle epilation. Modern devices with contact cooling (sapphire cooling tip) and high-quality gel reduce the sensation to a warm tingling or a light snap from a rubber band. Clinical studies confirm that over 90% of patients rate the pain scale as 0–3 out of 10 - at most 4–5 on the face and in the intimate area.From which skin type is IPL safe?
Very well and without restrictions for Fitzpatrick types I–IV (fair to Mediterranean skin). For types V–VI, IPL is only possible with special long-pulse devices (e.g., Nd:YAG-filtered IPL systems) and significantly lower energy, and should be performed exclusively by experienced dermatologists. Modern home devices have automatic skin sensors that completely block treatment when the skin is too dark.
Can IPL be used in the intimate area?
Yes, this is one of the most popular and safest areas. At low energy (usually level 1–3) and with sufficient gel, the treatment is very well tolerated there. Many dermatologists even specifically recommend IPL for the intimate area because it significantly reduces the rate of ingrown hairs and folliculitis - an effect confirmed in several studies.Why don't the hairs fall out immediately?
The light damages the follicle during the anagen phase, but the hair initially remains mechanically anchored in the skin. Over the following 7–21 days, it is pushed out by the natural growth cycle (“exogen phase”). This delayed shedding is a clear sign that the treatment was successful - immediate shedding would indicate only superficial coagulation.IPL or laser - which is better?
Both achieve comparable long-term results. IPL is more affordable, more versatile (acne, pigmentation, vascular lesions), and much better suited for home use. Lasers (especially diode and alexandrite lasers) are somewhat more precise for very dark hair and darker skin, but are more expensive and intense. A 2023 meta-analysis found no significant difference in hair reduction after 12 months between IPL and laser for Fitzpatrick types I–IV.
