Let there be light! LED treatments claiming to cure acne are now available as home kits - but are they safe?

When you’ve got acne or wrinkles, the last thing you want is for someone to come along and shine a light on your imperfections.

But an innovative home-use device requires you to do exactly that — with the promise of results that match up to professional-strength machines.

Treatments using the skin-repairing power of LED (light-emitting diode) light therapy are firm favourites with dermatologists and facialists.

Carla Bruni, Natalie Imbruglia and Sienna Miller are all said to be disciples.

But typical salon or clinic-based LED light treatment can cost more than £100 a go, and require six to 12 sessions.

Enter the Tanda Light Therapy Skincare System, a hand-held gizmo that mimics the light frequency used in clinic-based treatments, with the added bonus that you can use it in your own home, in your own time and at a fraction of the cost.

Developed in Canada, the mini-machines work by exposing the skin to different wavelengths of coloured light to gently and painlessly treat blemished complexions.

There are two devices, available only in Harvey Nichols.
