This is a terrible skin condition which is a relation to acne. Its symptoms are redness across the nose, cheeks, chin and forehead and small red pustules and inflammation. It becomes supersensitive and should not be treated as though it is acne.
Sometimes it can begin in middle-aged women with a simple flush of the face, and this is the most common group of people, though middle-age men get the bulbous nose that most people associate with alcoholism. No-one knows why it happens or what causes it.
It is however agreed that stress makes it worse, digestion problems are linked and wind and temperature changes exasperate the problem, as does red wine and caffeine.
Water is one of the cures (splashing face twice daily with warm water will help).
Try taking L-Glutamine (an amino acid) to help heal the gut and detoxify the digestive tract.
Vitamin A, Vitamin C (ester-C), zinc and iodine (kelp) will play their parts in repairing the skin. Grape seed extract will help (anti-oxidant).
Start a diary of eating habits and try to find your trigger. Cut out any possibles and see if it helps, then re-introduce and see if it flares up again.
