ABSTRACT

Facial rejuvenation using Botulinum toxin A is one of the most popular aesthetic procedures. Many cosmetic applications of Botulinum toxin A are under evaluation. Intradermal injection of Botulinum toxin A is a variation of the intramuscular injection technique and remains relatively new technique. This evaluates the effects of intradermal injection of Botulinum Toxin A on facial wrinkle lines. Thirty patients were included to undergo intradermal injections of Botulinum toxin A on forehead, cheek and periorbital area. Three sessions of injection were performed for 10 days. Clinical photograpahs were taken for 24 weeks, and evaluated patient's satisfaction and objective improvement of facial wrinkle lines. Improvement in patient's satisfaction and facial wrinkle line was noted in the post-treatment photographs. This effect was lasted for about 12 weeks. The intradermal injection of Botulinum toxin A is effective method for facial rejuvenation without obvious side effects.
