Intense pulsed light (IPL) is used to treat unwanted body and facial hair. The light emitted from IPL devices reduces hair growth by damaging individual hairs and therefore preventing their re-growth.

This technology has been used in specialist salons and clinics since the late 1990s, and home-use devices came on the market in America and Europe around 2007.

The challenge

Whenever a product moves from professional use to consumer use, there are a number of safety hurdles to overcome. In the case of IPL, manufacturers of home-use devices have put in place 'smart' controls to minimise the risk of injury to a user's skin or eyes through accidental exposure to the device's light.

However, these controls have to be balanced with the need to deliver effective treatment to the user.

This is achieved through measurement.

The solution

NPL scientists, together with academic and industrial partners, have developed standardised measurement methods for IPL devices.

These methods can be used to define an IPL device's output in terms of its energy measurement (fluence), pulse duration (exposure time on tissue), (homogeneity on tissue), spectral output ( or band of wavelengths), and time-resolved spectral output.

The impact

If applied correctly by manufacturers, these new measurement methods will safeguard people using home-use IPL devices.

This product (and others developed by CyDen) was rigorously tested during research and development using the new measurement methods NPL, CyDen and other partners devised. Therefore it would seem CyDen have the edge in a crowded market as they can offer their customers real assurances that they are using a safe, but effective in their own home.
