Benefits of technology

[0022]The compositions for treating, or ameliorating at least one symptom of, a skin pigmentation disorder or condition, in a subject in need thereof, are formulated for topical administration. By way of non-limiting example, the compositions of the invention can be in the form of a solution, an oil-in-water emulsion, a water-in-oil emulsion, a gel, an ointment, a patch, a paste, a liquid, a foam, a mousse, a spray, an aerosol, a triple emulsion, a nanoemulsion, a microemulsion, a hydrogel, a jelly, a dispersion, a suspension, and / or a tape. The compositions are stable, substantially free of calcium, do not cause an acnegenic / comedogenic response, and / or produce only minor skin irritation upon administration.

Problems solved by technology

However, the processes of melanosome maturation and melanosome transfer into the keratinocyte are currently far less studied and not yet understood.
However, melanogenesis and skin pigmentation can be disturbed or disorder, which may lead to undesirable pigmentation patterns.
Many of these previous examples were not acceptable or were of limited efficacy in treating skin pigmentation.
Most of these compounds have been described to address only a few steps of the multiple steps leading to melanin formation and ultimately skin pigmentation, which may result their limited efficacy.
In addition, many of these compounds have been found to be irritating to the skin and, therefore, undesirable for use.

[0110]Exemplary compositions formulated in accordance with the present invention are presented in Table 19. These compositions serve as illustrative formulations which provide several of the advantageous features of the invention, namely, mildness to the skin after application with no or only limited skin irritancy; clearness and non-greasiness upon application (transparent) to face and other skin areas other than the palms and the soles; and quick-drying, particularly when the compositions are preferably formulated as water-in-oil formulations.

Abstract

The present invention provides compositions containing one or more calcium sequestration agents and methods for topical application of such compositions to the skin to treat skin pigmentation disorders, such as melasma, post-inflammatory hyperpigmentation, pigmentation changes due to skin aging, or any other skin conditions related with normal such as skin of color or abnormal pigmentation such as hypo- or hyper-pigmentation in humans.

Description

RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 12 / 688,107, filed Jan. 15, 2010 which claims priority to U.S. Ser. No. 61 / 145,325, filed Jan. 16, 2009, both of which are herein incorporated by reference in their entirety.FIELD OF THE INVENTION[0002]The invention relates generally to compositions containing one or more calcium sequestration agents and methods for topical application to the skin to treat skin pigmentation disorders, such as melasma, post-inflammatory hyperpigmentation, pigmentation changes due to skin aging, or any other skin conditions related with normal such as skin of color or abnormal pigmentation such as hypo- or hyper-pigmentation in humans.BACKGROUND OF THE INVENTION[0003]In humans, skin color arises from a complex series of cellular processes that are carried out within a group of cells known as melanocytes. Melanocytes are located in the lower part of the epidermis and their function is to synthesize a pigment...
