Abstract

Crow's feet are a sign of skin aging. Currently, Botulinum toxin injection is considered safe and highly effective treatment. We conducted a study on 60 patients diagnosed with crow's feet at the Department of Stem Cell Research and Application of the National Hospital of Dermatology, from July to December 2020 to evaluate the effectiveness and side effects of Botulinum toxin type A injection. The effectiveness is evaluated based on the reduction of Facial wrinkle scale. The results showed that after 1 month of treatment, all patients improved, of which 83.3% improved significantly. Side effects were low, 3 patients (5%) had post-injection bruising and 3 patients (5%) had a feeling of eyelid tightness during the first week which subsides after one month.
