What effects does it have?

What is it?

Permanently reducing the amount of hair by burning the hair and follicle using an extremely bright light pulse.

It's also known as Intense Pulsed Light.

How long does it last?

The effects of IPL hair removal are permanent and cannot be reversed. IPL reduces the amount of hair significantly, but does not guarantee all hairs will be permanently removed, so later 'top-up' sessions may be needed.

More information

Intense pulsed light (IPL) therapy is an alternative to laser hair reduction.

It uses a bright flash of light from a xenon flashbulb that produces many different wavelengths - rather than the single wavelength used by a laser.

Medical studies have yet to come to a clear conclusion about whether IPL is more or less effective than laser hair reduction. Some studies have suggested that treatment with IPL is less effective 1,2, while others have found no difference 3,4.

IPL is less suitable than laser hair reduction for people with darker skin 3.

IPL hair reduction may be painful or uncomfortable. You can reduce the discomfort by asking your GP to prescribe you lidocaine and prilocaine cream, also known as EMLA cream. This is a local anaesthetic, applied directly onto the skin, which numbs the skin so you feel less pain from the treatment. You will normally need to apply the cream around an hour before your treatment.
