Collagen production enhancer
European Patent Application EP2438922
Publication date: April 11, 2012
Assignee: SofSera Corp.

This invention describes a collagen production-enhancer containing calcium phosphate fine particles that act on fibroblasts and ameliorate aging phenomena such as wrinkles and sagging; the particles also reconstruct damaged collagen fibers in tissues to convert them to normal tissues. According to the inventors, the average particle diameter of the calcium phosphate fine particles is very small, therefore they also ameliorate skin texture by coating the skin surface. Further, when a sintered body is used, significantly increased collagen production is exhibited. According to the invention, an effect of promoting rapid penetration into the dermis and astringent, moisturizing, and anti-inflammatory effects are also exhibited by the materials.

Anchoring compositions for topical film-forming and sustained release
European Patent Application EP2438908
Publication date: April 11, 2012
Assignee: Vectum Pharma S.L.

Disclosed herein is an amphiphilic copolymer that can be used in film-forming compositions for dermal applications. The copolymer is characterized by a defined structure with a hydrophilic polymer backbone and pendant hydrophobic groups. It rearranges when it comes into contact with the lipid-rich domains of the outermost layer of skin, resulting in stable film formation. When containing active ingredients that are covalently attached, such as sunscreens, humectants or colorants, the copolymer immobilizes the active ingredient on skin. It may also contain agents such as fragrances, cosmeceuticals or dermatologically active drugs covalently attached that can be degraded under the physiological conditions found on skin, resulting in sustained release of the immobilized active ingredient.
