Blue light for skin problem

tHiS week: Philips BlueControl, £259, philips.co.uk

THIS device emits blue light and is designed to treat psoriasis, where skin cells are replaced too quickly, leading to raised patches of silvery scales known as ‘plaques’, which can become inflamed and painful.

The device is designed to be used for 30 minutes a day for three months.

EXPERT VERDICT: Although blue light therapy has been used to treat conditions such as eczema, this is the first time it’s been used for psoriasis at home, says Dr Anton Alexandroff, a consultant dermatologist at Leicester Spire Hospital. ‘This new device is innovative and exciting and research so far suggests it is safe.’ He adds: ‘When exposed to blue light, skin cells produce chemicals that reduce the rate at which the cells proliferate. Studies have been very encouraging, with 84 per cent of people noting an improvement after using this daily for three months. ‘It is too early to say how effective it’ll be long-term, but there are no reasons to expect harmful side-effects. ‘However, unlike taking a tablet or using a cream, which can reduce inflammation in the whole body, this device can only treat small areas of skin at a time, so may be impractical to treat severe psoriasis affecting large areas.’
