treatment depends on the cause
if it is hormonal, treatment is hormonal balance
if it is food, and yes I don’t care what they say some foods can cause breakouts (had chocolate several times in the last couple of weeks, after several months w/o and am now broken out again)
if it is allergic reaction or sensitivity you have to hunt down and eliminate the cause
if it is medication related, you might have to wait until you stop taking the meds
and so forth.
it can be allergies, sensitivities to some agent, excessive oil production (or not enough) due to some cause, sebhorrea (sp.) which can also cause what looks like dandruff, rosacea, or drug reaction.
the generic cleanser and cosmetic that seem to work best for em is witch hazel and aloe vera. I use tea tree oil based lotion on skin eruptions that seem to be caused by yeast or fungus (common among diabetics and often requires sytemic treatment).
and just when you figure out the cause it may go away by itself. or not.
