Eyeseryl® is a tetrapeptide with anti-edema properties with proven efficacy in reducing puffy under eyebags in as little as 15 days.  It can be incorporated in cosmetic formulations such as gels, serums, and emulsions where a reduction of puffiness under the eyes is desired. Studies were performed with Eyeseryl® at a very low concentration (1%) in order to define a minimum concentration for which an effect could be measured. Both eyebag volume and dark circles were moderately, but significantly reduced.  Up to 10% of the solution can be incorporated into formulations to obtain significant eyebag-reducing activity.
