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. |
