Effect of botulinum toxin A on facial wrinkle lines in Koreans.

Two kinds of botulinum toxin type A were clinically evaluated in rhytidectomy. Twenty Korean patients with facial wrinkles were fully assessed following treatments with random injections. The mean degree of wrinkles before the injections was 2.83 and the mean corrective effect was 70.0% at least 3 months afterward. The effect lasted less than 6 months in only 9 cases. The complications were tingling sensations in 3 cases (15.0%), temporary lid swelling in 5 cases (25.0%) and lagophthalmos in 3 cases (15.0%). No serious or permanent adverse effects were observed. Botulinum toxin type A rhytidectomy was a very effective method of removing various facial wrinkles although the treatment for complications and side effects will need to be considered.
