Patent

CA 2695386

Visible light-activated polymer cosmetic filler preparations useful in a variety of applications are provided. In some embodiments, the photo-activated polymer composition comprises a conventional polymeric material, such as HA, together with a modified, cross-linkable polymer, such as PEG or PEODA, to permit the formation of crosslinks within the polymer matrix in situ on exposure to a visible light source, such as an IPL device. The preparations provide for a more stabilized composition that is contourable during gelation.

L'invention concerne des préparations de charge cosmétiques polymères activées par la lumière visible utiles dans une variété d'applications. Dans certains modes de réalisation, la composition polymère photo-activée comprend un matériau polymère classique, tel que le HA, combiné à un polymère réticulable modifié tel que le PEG ou le PEODA, pour permettre la formation de réticulations au sein de la matrice polymère in situ au moment de l'exposition à une source de lumière visible, telle qu'un dispositif IPL. Les préparations produisent une composition mieux stabilisée qui peut être profilée en cours de gélification.
