Is IPL healthy? The facts about safety, radiation, and your skin

October 24, 2025

What exactly is IPL?

IPL stands for Intense Pulsed Light, a technology that uses flashes of light to reduce hair growth at the root. It has now become a popular method for long-term hair removal, both in professional salons and at home with specially developed devices.

However, we often get the question: is IPL healthy? Understandably. Because as soon as light and skin meet intensively, questions arise about safety, radiation, and possible risks to the skin. In this blog, we will provide an honest and clear answer to that.

IPL and radiation: is it harmful?

No UV radiation

The term 'flash of light' can quickly conjure up associations with UV radiation, which we know from sunlight and tanning beds. UV radiation can damage the skin and, in the long term, even contribute to skin aging and skin cancer.

Important to know:
An IPL device uses flashes of light that have a different wavelength than UV. UV light is actively filtered from the light spectrum used by IPL devices. So your skin is not exposed to extra UV radiation during a treatment.

IPL does not increase the risk of skin cancer.

Is IPL safe for your skin?

IPL technology is designed to work in a targeted manner. The light flash is directed through the pigment in the hair to the hair follicle. There, the light is converted into heat, which temporarily weakens or disables the hair root.

What does this mean for your skin?

The skin itself is not damaged, as long as you use the device correctly.
IPL devices for home use, such as those from Laesera (Nova One), are equipped with built-in safety filters and skin detection.
IPL is non-invasive; nothing is inserted into or damages your skin.
The skin may feel slightly warm or pinkish immediately after use. This is temporary and normal.

Tip: Use a soothing cream or aloe vera gel after treatment for extra comfort.

Side effects and contraindications

As with any technology, it is important to know when you should not use IPL, or when you should be extra careful.

Possible side effects (temporary and rare):

Redness or slight swelling (often gone within a few hours)
Sensitivity if the intensity is too high or if used on an unsuitable skin type

When it is best not to use:

During pregnancy or breastfeeding
On sun-tanned or sunburned skin
With certain skin conditions such as eczema, psoriasis, or active acne
When using medication that causes photosensitivity

Advice: Always consult the device's manual and, if in doubt, consult a doctor or skin therapist.

How reliable are IPL devices for home use?

This question is very common among people considering using IPL themselves. Rightfully so. Because while the technology is good, safety also depends on application.

What to look for in home use?

CE-certified devices with skin safety sensors
Multiple light intensities, so you can adapt to your skin type
A clear, understandable manual
Positive user experiences and transparency from the brand

Reliability is not only in the technology, but also in how honestly and carefully a brand communicates what the product can and cannot do.

Honest about effectiveness

An IPL device is not a miracle cure, we are happy to add that.
It gradually reduces hair growth, usually after 4 to 12 weeks, depending on your hair type, skin type, and frequency of use. Completely hairless? That's not realistic, but long-lasting smoothness? Absolutely achievable.

Key message: IPL is effective, provided it is used correctly and consistently.
