These darks spots are signs of postinflammatory hyperpigmentation (PIH). This This is a frequent and transient (so temporary) complication of croton oil peeling. Permanent problems have not been seen. Best is to continue the daily application of tretinoïn- and hydroquinone-ointment that you have received from us before the peeling for 3 to 6 weeks. It will help to remove the hyperpigmentation. Also it is very important for you to stay out of the sun until 6 months after the peeling and use the sunblocker that we gave you.
