The present invention relates to methods for enhancing, extending and accelerating the cosmetic benefits certain non-surgical dermal interventions, examples of which include treatment with aesthetic injectables such as botulinum toxin and dermal fillers, as well as intense pulsed light (IPL) treatments, particularly cosmetic treatments characterized by the injection of botulinum toxin compositions, such as Botox® and Dysport®, and/or dermal fillers, such as Restylane® and Juviderm®. More particularly, the present invention relates to the unexpected discovery that the combination of micron-sized particulate bioactive glass and medical grade hyaluronic acid yields a cosmetic composition that is capable of improving and prolonging the anti-wrinkle effects of such cosmetic therapies as well as to afford enhanced and improved healing and anti-microbial benefits at the site(s) of injection.
