IPL (Intense Pulsed Light) hair removal is a highly sought-after treatment among women in the UK who wish to achieve a permanent solution for unwanted hair. It works to progressively suppress hair growth by targeting hair follicles with pulses of broad-spectrum light. Given the availability of inexpensive and convenient home devices, it's a viable option over costly salon treatments.
However, knowing about IPL hair removal side effects is necessary to ensure safety and effectiveness. Outcomes may differ based on skin colour, hair colour, quality of device, and how well you adhere to safety precautions. Disregarding precautions can result in problems such as irritation, burns, or unsymmetrical outcomes. Here are five typical mistakes, and easy tips to make smoother, safer treatments at home.

What are IPL Hair Removal Side Effects?
For long-term hair reduction, IPL hair removal is a popular choice in the UK. IPL hair removal side effects can range from minor skin irritation to less common, more severe reactions, so it's important to be aware of them like you would with any cosmetic procedure.
Common IPL Hair Removal Side Effects After Treatment
For most women using IPL at home or in clinics, side effects tend to be temporary and mild. It’s perfectly normal to notice some redness or sensitivity immediately after a session—that’s a sign the light pulses have effectively targeted the hair follicles.
Common little reactions include:
- Redness that sticks around for a day or two
- Slight swelling around the hair follicles
- Skin feeling a bit tender, like after a gentle sunburn
- Itching or tingling sensations
- Temporary changes in skin colour—either darkening or lightening
These usually settle within a few days. To help your skin heal and feel comfortable, using soothing aloe vera, avoiding too much sun, and staying well-hydrated can make a difference.
More Serious Risks to Consider
While many people have smooth sailing with IPL, some more serious IPL hair removal side effects can happen, especially if the device isn’t used correctly or if your skin isn’t a good fit for IPL treatment.
Potential risks include:
- Burns or blistering, especially on darker or recently tanned skin
- Persistent hyperpigmentation (dark spots) or hypopigmentation (light patches)
- Scabbing or crusting over treated areas
- Scarring in extreme cases
- Bacterial infections due to poor hygiene or improper aftercare
These side effects are more likely if the wrong settings are used, if treatment is repeated too frequently, or if proper skin prep and aftercare are neglected.
Factors That Influence IPL Hair Removal Side Effects
IPL (Intense Pulsed Light) hair removal is a popular choice, but side effects can vary depending on your individual characteristics. Key factors like skin tone, hair colour, device use, and health status all influence how your skin might react.
Skin Type
If you have a darker skin tone (Fitzpatrick types V and VI), or have recently been tanning—whether outdoors or on a sunbed—you may be more prone to burns or pigmentation issues. Always consult a trained practitioner before treatment.
Hair Colour
IPL is most effective on dark hair. If you’re naturally blonde, red, or grey-haired, the treatment may not deliver the best results and could cause more skin sensitivity.
Proper Use of the Device
Whether you’re going to a clinic or using a home IPL device (which is widely available in the UK), improper use is a common cause of side effects. To stay safe: • Read the manufacturer’s instructions carefully • Start on the lowest setting for your skin tone • Don’t treat sunburned or broken skin.
Medical Conditions and Medications
Some medications, including certain antibiotics and hormone treatments (like the pill or HRT), can increase light sensitivity. Skin conditions such as eczema or rosacea may also be aggravated. Always check with your GP or a skin specialist before starting IPL.
5 Common Mistakes That Lead to Side Effects in IPL Hair Removal Treatments and How to Avoid Them
IPL hair removal is successful, largely depending on skin tone and hair colour contrast. High contrast, like light skin with dark hair, usually works best. The IPL machine can easily be directed at the dark hair pigment without influencing the surrounding light skin.
On the other hand, with little contrast, like dark skin and hair, the IPL machine may target the skin by mistake. This can lower its effectiveness.
Mistake 1: Skipping Patch Tests Before Full IPL Treatment
Many skip the patch test before starting IPL hair removal, but it's a vital safety step. This simple test helps identify how your skin will react, especially in sensitive areas, and can prevent serious side effects.
Patch testing shows whether IPL is suitable for your skin tone and type. Even if you’ve had treatments before, reactions can vary. By testing a small 2–3 cm area first (ideally on the same body part you plan to treat), you reduce the risk of issues like burns or pigmentation problems. Use the lowest setting, follow all prep steps, and monitor the skin for 24–48 hours.
Skipping this step means you’re going in blind. Without testing, IPL hair removal side effects can include:
- Blistering or burning
- Dark or light patches on the skin
- Long-term marks or scarring
- Wasted money on unsuitable treatment
Those with darker or recently tanned skin are especially at risk and should be extra cautious. Always perform a separate patch test for areas like the face or bikini line, as they’re more sensitive.Taking a few extra minutes to test first can save you from long-lasting skin damage.
Safety
Prevents adverse skin reactions.
Mistake 2: Improper Shaving Technique Before Treatment
To reduce IPL hair removal side effects, shaving 12 to 24 hours before your session is key. This timing allows your skin to calm down from any irritation while ensuring the hair is short enough for IPL to work effectively.IPL targets the pigment in the hair root. If the hair is too long, the light can heat the hair above the skin, causing discomfort or even burns. That’s why shaving—not waxing or using hair removal creams—is essential. Those methods remove the root, making IPL ineffective.
Tips for Safe Shaving:
- Use a clean, sharp razor
- Shave in the direction of hair growth
- Moisturise afterwards to soothe the skin
Avoid These Common Mistakes:
- Shaving right before treatment – can lead to sensitivity and stinging
- Leaving hair too long – raises the risk of burns
- Using blunt razors – increases cuts and irritation
- Skipping shaving – results in patchy treatment and more side effects
For sensitive areas like the bikini line, use a separate razor and take extra care. A smooth, properly shaved surface helps IPL deliver safe, even results with fewer risks.
Mistake 3: Ignoring Skin Preparation & Aftercare Guidelines
Neglecting skin prep and aftercare is a major cause of IPL hair removal side effects. Many unknowingly apply products like retinoids or acids too close to treatment, leading to irritation, burns, or pigmentation.
Before Treatment: Stop using strong skincare products—like retinol and acid-based toners—at least 48 hours beforehand. These make the skin more sensitive to light. Cleanse gently with a fragrance-free wash and skip moisturisers, deodorants, and especially fake tan. If you've used self-tanner, wait two weeks before treating that area.
After Treatment: Your skin will be more vulnerable, so go easy on it.
- Wear SPF 30+ daily , even in cloudy British weather
- Avoid tight clothing ; choose loose cotton fabrics
- Skip heat —no hot showers, gyms, or sunbeds for 48 hours
- Simplify skincare with gentle, hydrating products only
IPL might seem simple, but your skin needs proper care before and after. Do it right, and you’ll get smoother, safer results with fewer side effects.
Mistake 4: Overusing the IPL Device on the Same Area
With the growing popularity of at-home IPL hair removal, it’s tempting to think more frequent treatments mean faster results. But overusing your device can do more harm than good. Treating the same area too often increases the risk of IPL hair removal side effects such as redness, irritation, sensitivity, and even long-term skin damage.
Most trusted at-home IPL devices recommend waiting at least 48 hours between treatments in the same area. This schedule supports skin recovery and ensures hair is targeted during its active growth phase. Ignoring these guidelines may reduce effectiveness and raise your risk of:
- Burns and blistering , especially on delicate areas
- Hyperpigmentation , more likely in medium to dark skin tones
- Scarring or texture changes due to repeated skin stress
Over-treating is like over-exercising—your skin needs time to recover.
Use a calendar or app to track sessions, and if your skin feels irritated, take a longer break. A steady, well-spaced routine helps avoid side effects and leads to smoother, safer results.
Mistake 5: Not Wearing Protective Eyewear During Treatment Sessions
IPL devices use intense pulsed light, which can seriously harm your eyes if not properly protected. The flashes can damage the retina, leading to light sensitivity, eye strain, or even permanent vision loss.
Simply closing your eyes isn’t enough—light can pass through your eyelids. Unlike sunglasses, IPL safety goggles are designed to block this specific type of light. In UK clinics, wearing eye protection is mandatory during IPL treatments, and the same care should be taken at home.For added safety, use protective stickers or shields on closed eyelids during facial treatments.
Eye Safety Tips:
- Always wear the goggles provided with your device
- Ensure a snug fit with no gaps
- Replace scratched or damaged goggles
The NHS has reported eye injuries from improper IPL use, highlighting how vital eye protection is. No beauty result is worth damaging your vision—prioritise safety every time.
Conclusion
Safe IPL hair removal isn’t guesswork—it’s about proper prep, smart habits, and protecting your skin. Across the UK, achieving smooth, hair-free skin at home is completely possible when you follow best practices and avoid common mistakes.
Stick to your treatment schedule, protect your eyes, and pause if anything feels off. Your skin deserves careful attention, not rushed decisions. By respecting your skin’s needs and learning from others’ missteps, you reduce the risk of IPL hair removal side effects like irritation, burns, or uneven results.
