Post-inflammatory hyperpigmentation (PIH) developing after cosmetic procedures, like chemical peeling and laser therapies is always a concern, but has not been reported with Plasma Exeresis (PlexR®). Plasma exeresis is considered to be a safe method suitable for all skin types, because of the minimal dermal damage according to the manufacturer and as shown in research. It is an effective non-surgical treatment as an alternative for surgical upper and lower blepharoplasty. Plasma is formed by this device through the ionization of atmospheric gas. After the treatment a crust on the treated part will form that falls off in about a week, normally leaving no bruising or scarring. In this article we describe two cases of PIH after plasma exeresis. The PIH in the first patient (Fitzpatrick skin type II) was successfully treated after four months with topical application of hydroquinone 5%/tretinoin 0.05% and with a superficial herbal peel. In the second patient (Fitzpatrick skin type IV) the same treatments were used with limited result after which four times thermo-mechanical ablation (Tixel® on mode 10/500) was used which leaded to further improvement but not a complete disappearance of the PIH after 9 months.
