Rosacea sufferers sometimes bring up the topic of computer screens and indeed lighting in general as a trigger for their rosacea. Sadly there seems to be little conclusive literature available on this topic.
- A 1985 study in Norway, Does visual display terminal work provoke rosacea? was able to show that rosacea and seborrheic dermatitis sufferers were over represented in the their group of VDT users. They were unable to find whether their usage of computer screens aggravated those symptoms or not.
- A study in 1989, Facial skin complaints and work at visual display units. Epidemiological, clinical and histopathological studies, came to a similar conclusion, also being unable to prove why the VDU users had skin symptoms more often than non VDU users.
- A study in 1990 titled Facial skin complaints and work at visual display units. A histopathological study was unable to find any difference between VDU users and non VDU users when examining for eg. demodex folliculorum, number of mast cells and hyperplasia of sebaceous glands, occurrence of telangiectases, or intensity of inflammatory infiltrate.
It even makes me wonder if long term computer users might need a bit more sunshine to have healthy skin ? This is the trouble with proving this sort of connection, there are so many possible causes that it is difficult to isolate one factor.
This recently published paper, written in Italian, looks like it could be interesting. If you have access this journal online, please feel free to send me a copy.

Skin disorders like rosacea, seborrhoeic dermatitis, non-specific erythema and acne can be VDU work linked. At present, many environmental and individual causes are involved in the development of these disorders, but the former appear to be the issue to investigate more in depth.
What about you ? Have you found that lighting or computer use worsens your rosacea ? Have you found strategies to help ?

Allow me to suggest a possible causal link. These studies were all done before LCDs became common, so the test subjects were all using CRTs.
CRTs, like any TV tube, generate lots of static electricity and will attract dust. When the CRT is on your desk, everything around it becomes charged with static, including YOU. So dust is attracted to your body, including your face. I’ve discussed this problem with hundreds of CRT users, after they complained of eye strain. I told them this story, and suggested it’s dust in their eyes. The solution is to make sure your CRT is kept clean, is well grounded (no cheater plugs and overloaded power strips) and to ground yourself occasionally (touch something metal that’s grounded, like your CPU case) to drain the charge off your body. Most of my clients described less eye irritation after following my advice.
So there’s your possible link. Dust and environmental irritants are attracted to CRT users’ faces, due to stray static electricity charges generated by the CRT. And we all know what environmental irritants do for our rosacea.
Thanks for your thoughts Charles, I haven’t heard many explanations and I had never thought of this before.
