5 Mistakes to Avoid When Using IPL Hair Removal at Home

At-home beauty tech has come a long way, and one of the most popular innovations is IPL (Intense Pulsed Light) hair removal. These devices are marketed as a safe, effective alternative to professional treatments, offering long-term hair reduction in the comfort of your own home. With regular use, they can significantly reduce hair growth, and for many people, that means ditching razors, waxing appointments, and ingrown hairs for good.

But like any skincare or beauty tool, IPL devices come with a learning curve. Misusing them can lead to ineffective results—or worse, skin irritation and injury. If you’re considering adding IPL to your routine or you’ve already started but aren’t seeing the results you expected, here are five common mistakes to avoid when using IPL hair removal at home.

1. Using IPL on Unsuitable Skin or Hair Types

IPL works by targeting the pigment (melanin) in hair follicles. This means it’s most effective on people with lighter skin tones and darker hair. If your skin tone is darker, the device may not be able to distinguish between your skin and hair pigment, which can increase the risk of burns or discoloration. On the flip side, if your hair is too light—such as blonde, red, grey, or white—there may not be enough pigment for the light to target effectively.

Many modern devices include safety sensors to detect skin tone compatibility, but it’s still crucial to read the product’s guidelines carefully before use.

What to do: Always do a patch test on a small area first. If your device includes a skin tone sensor, use it! And if you’re unsure whether you’re a good candidate, consult a dermatologist before starting.

2. Skipping the Shaving Step

One of the most common and misunderstood steps in IPL prep is shaving. Many people assume they should wax or epilate before IPL since those methods remove hair from the root. However, this is counterproductive. IPL targets the hair follicle beneath the skin, so you need the follicle intact for the treatment to work.

Shaving, on the other hand, removes hair at the surface while leaving the root in place, making it the perfect pre-IPL step.

What to do: Shave the area 12–24 hours before your session. This reduces the risk of surface burns and allows light to travel efficiently to the root.

3. Being Inconsistent With Treatments

Consistency is key when it comes to IPL hair removal. Many people expect instant results after one or two sessions and feel disappointed when the hair grows back. But IPL isn’t a quick fix—it’s a gradual process that requires regular use over several weeks or months.

Hair grows in cycles, and IPL can only target hair that is in the active growth phase (anagen phase). That’s why multiple treatments are necessary to catch all the follicles over time.

What to do: Stick to the treatment schedule outlined by your device’s manufacturer—typically once every 1–2 weeks during the initial phase, then once a month for maintenance. Set calendar reminders or use a treatment tracker to stay on top of your sessions.

4. Using IPL on Tanned or Sunburned Skin

Using IPL on freshly tanned or sunburned skin is a big no-no. When your skin is exposed to the sun, its melanin levels increase, which can confuse the IPL device. This can lead to burns, hyperpigmentation, or irritation. Even a light tan can increase your skin’s sensitivity to the light pulses.

What to do: Avoid tanning—whether it’s from the sun or a tanning bed—for at least two weeks before and after IPL treatments. Also, avoid using the device on sunburned or irritated skin, and always wear SPF on treated areas if they’re exposed to sunlight.

5. Starting on the Highest Intensity Level

It might be tempting to turn your device to the highest setting, thinking it’ll give faster results. Unfortunately, this can backfire—literally. Higher intensity settings can cause redness, swelling, or even blisters if your skin isn’t used to it or if the level is too strong for your skin tone.

Most devices offer multiple settings, allowing you to ease into the treatment and give your skin time to adjust.

What to do: Start at a low or medium-intensity level, especially for your first few sessions. If your skin handles it well, you can gradually increase the intensity over time. Never exceed what feels comfortable, and stop immediately if you feel burning or sharp pain.

Final Thoughts

At-home IPL devices can be a fantastic investment for long-term hair reduction, provided they are used correctly. Avoiding these five common mistakes—using it on incompatible skin or hair, skipping the shave, being inconsistent, treating sun-exposed skin, and overdoing the intensity—can make all the difference in your results.

Be patient, follow the instructions, and take care of your skin before and after each session. With consistent use and the right approach, you’ll be well on your way to smoother, hair-free skin—all without leaving home.
