IPL for facial blushing is rarely effective
Intense pulse light (IPL) is rarely effective in treating facial blushing (flushing). Facial blushing is a variant of hyperhidrosis and is best treated with sympathectomy, not IPL. IPL is effective in treating facial blushing in about 10% of cases and is quite expensive, costing approximately 3000 dollars for 6-8 treatment sessions.
IPL is useful for facial redness caused by rosace. In a recent article published in the British Journal of Dermatology (September 2008), IPL was shown to "significantly reduces erythema and telangiectasia of rosacea and this is sustained for at least 6 months".
