US Patent Application 20110206625
Publication Date: Aug. 25, 2011
Assignee: SM Singh and DJ Tobin

The present invention relates to compositions and methods useful in studying or modulating melanin pigmentation in the skin. Particularly, the invention relates to compositions comprising a substance capable of modulating the activity or expression of ALK6 (SEQ ID 2) or Cdc42 which in turn are capable of modulation of the transfer of melanin from melanocytes to keratinocytes and potentially from keratinocytes to keratinocytes.

Cosmetic composition for lightening or unifying the complexion
European Patent Application EP23599
Publication Date: Aug. 24, 2011
Assignee: L'Oreal

The present invention relates to a composition comprising, in a physiologically acceptable medium, concave or annular particles, especially in the form of hollow sphere portions, the said particles comprising a matrix that is colored in the bulk. The present invention relates to a composition for topical application, intended, especially in the case of skin displaying dyschromia of the type caused by pigmentation marks, red blotches or shadows under the eyes, for lightening or unifying the complexion.

The composition according to the invention may especially be a skin care product or a makeup product, especially a foundation. It is commonplace for people with colored skin, or with pigmentation marks, red blotches or shadows under the eyes, to wish to correct these types of cutaneous dyschromia, and for this purpose use cosmetic or dermatological compositions that allow the complexion to be lightened and unified. To this end, it is known practice to use cosmetic compositions containing bleaching agents. However, it is necessary, to use these agents for a prolonged period and in large amounts in order to observe a bleaching effect on the skin. Furthermore, an effect is not observed immediately on application of the compositions comprising them. For the purpose of immediate lightening and unifying of the complexion, it is also known practice to use cosmetic compositions containing fluorescent compounds, with a particular focus on optical brighteners.
