The article reports an up-to-date classification of complications of cosmetic procedures and two clinical cases where multicomponent gel based on troxerutin, heparin sodium and depanthenol was used to rehabilitate patients after cosmetic procedures complicated by ecchymosis, hematomas and edema. In the first case a 30-year-old patient had a procedure to give greater volume to her lips and to correct their asymmetry with hyaluronic acid filler. The procedure was complicated by the formation of hematomas and edema. To minimize the edema and hematomas and to avoid the risk of infection the patient was prescribed 0.05% aqueous solution of chlorhexidine bi-gluconate once per day and taking of multicomponent gel based on troxerutin, heparin sodium and depanthenol two times per day for seven days. By the fifth day there was observed a significant decrease in edema of the lip area and almost complete resorption of hematomas. In the second case a 42-year-old patient had a procedure of a biorevitalization with unstabilized hyaluronic acid complicated by the appearance of ecchymosis up to 12 mm in diameter and edema in the periorbital zone. A 0.05% aqueous solution of chlorhexidine bi-gluconate once per day and a multicomponent gel based on troxerutin, heparin sodium and dexpanthenol twice per day for seven days were prescribed as post-procedural rehabilitation. By the fourth day clinical improvement was noted. The edema disappeared, the color changed, the size of the ecchymosis decreased to 4 mm. The ecchymosis disappeared completely on the sixth day. In addition, the main characteristics of troxerutin, heparin sodium and depanthenol as components of a multicomponent gel were considered. A multicomponent gel based on troxerutin, heparin sodium and depanthenol as supportive aid helped to get complications completely cleaned out and significantly reduced the rehabilitation period for these patients. The authors consider it possible to recommend it as a means of post-procedural rehabilitation. © 2021, Remedium Group Ltd. All rights reserved.
