Hi.Dark circles or Periorbital darkening is a very common problem.But eliciting the cause is very important.It may be hereditary or due to vascular causes.Periorbital Melanosis responds well to Retinoic Acid derivatives and Arginine peels. But if the darkening is due to a vascular cause,then RF tightening may be of help.Please visit your Dermatologist for guidance regarding the same.
