ClinConnect Summary

This clinical trial is looking at how botulinum toxin, often known as Botox, can be used to slim the neck by injecting it into a muscle called the sternocleidomastoid (SCM). While Botox is commonly used for cosmetic reasons, this study aims to see if it can also help create a more youthful and feminine neck appearance by reducing the size of this muscle.

To participate in the study, you need to be between the ages of 18 and 75 and be interested in achieving a more feminine neck look. However, you cannot have had any Botox injections in the SCM muscle in the last year, nor can you be taking certain medications like blood thinners or planning to lose or gain significant weight during the study. If you are pregnant, breastfeeding, or have had an allergic reaction to Botox in the past, you would also be excluded from the trial. If you are eligible and decide to join, you can expect to receive injections and help researchers understand the effects of this treatment on neck appearance.
