IPL for under eye circles

IPL may provide modest benefit at best for under eye circles. Unfortunately there is nothing currently outstanding for this troublesome observation. There are various factors that can cause dark circles under the eyes (e.g. eczema, dry skin, genetics, superficial blood vessels etc) which should be assessed by your dermatologist. Sometimes there is simply a shadowing effect due to a too prominent tear trough, and in this case an injectable hyaluronic acid filler is an excellent option. Vitamin C and retinol/tretinoin based creams can provide some modest benefit as well, but don't overdo it since irritation of the thin skin around the eyes will make things even darker.
