Energy-saving light bulbs can be bad for your skin, doctors are warning.
The fluorescent devices produce a more intense light and can aggravate a range of existing problems, especially in those with light-sensitive conditions.
There have been growing concerns that low-energy light can trigger migraines, as well as dizziness, loss of focus and discomfort among those with epilepsy.
There have also been complaints from sufferers of lupus - an auto-immune disease causing many symptoms including pain.
The latest warning was issued by Spectrum - an alliance of charities working with people with
light sensitive conditions - and the British Association of Dermatologists (BAD).
Critics complain low-energy lights are either "cold" or "green," take up to a minute to warm up properly and because they are fluorescent, flicker.
