The first impression of a person is influenced by facial appearance and improved by cosmetic surgery.
The researchers wanted to determine whether or not the use of botulinum toxin A (Botox) would contribute to a person receiving higher scores on a variety of first impression scales.
During the study, the researchers took photo of the participants before and after the treatment with the botulinum toxin A.
The photos were randomly divided into books with each subject represented only once per book.
Blinded evaluators completed a survey rating their first impression on various measures of success for each photo in the book.
The participants who received the injections improved first impression scores for scales of dating success, attractiveness, and athletic success.
However, they did not find any positive correlation between Botox injections and increased scores regarding social skills, financial, or relationship success.
The study was presented at the 2008 American Academy of Otolaryngology - Head and Neck Surgery Foundation (AAO-HNSF) Annual Meeting and OTO EXPO in Chicago, IL.
