This composition based on lipid vesicles dispersed in an outer phase is characterized in that it contains at least one melanin pigment in the aqueous outer phase. The melanin pigments may be carried on mineral or polymeric fine particulate or lamellar fillers. The composition obtained can be used in the field of cosmetics where it makes it possible to obtain a highly homogeneous dispersion of the melanin pigment that can be distributed evenly over the skin or hair; it increases the period of protection of keratinous substances against the harmful effects of ultraviolet radiation; it promotes tanning of the skin and gives it an even color and better appearance; it colors grey hair; and it causes improved storage of the melanin pigment in the stratum corneum. |

The invention relates to a preparation for topical use, having light protection properties and in a special application form. In the known light protection agents containing the naturally occurring active compound melanin, the problem is inadequate transport of the melanin to its site of action. According to the invention, this problem is solved by a preparation for topical use which is characterised in that it contains melanin, dissolved or dispersed in one or more fluorocarbons, which are present as asymmetric lamellar phospholipid aggregates in an aqueous system together with a phospholipid, with a particle size of the aggregates in the range from 200 to 3000 nm. |

A melanin that is soluble in an aqueous solution at a pH between 5 and 9 at a temperature of 0.degree. to 100.degree. C. Advantageously, the melanin is capable of being filtered through at least a 0.45 micron size filter, and has a molecular weight of greater than 10,000 kilodaltons. The melanin is useful for providing a naturally-appearing tan to mammalian skin and hair. Such melanin can be produced by combining dopachrome and an appropriate enzyme, or by incubating 5,6-dihydroxyindole-2-carboxylic acid alone or with 5,6-dihydroxyindole, or with 3-amino-tyrosine. The melanin is also useful for providing a sun-screen to mammalian skin and hair, to treat post-inflammatory hypo- and hyperpigmentation, to tint glass and plastic, to protect industrial materials against ultraviolet damage, and as a coloring agent in foodstuffs such as coffee, tea, soda, whiskey and liquors. |

C., the rubber component being present in the paste composition in the range of about thirty percent to about seventy percent by weight. The present inventive paste compositions can be freely formed with the fingertips or a spatula; they are less irritating to the skin, mucosa and/or the injured area; and they are less susceptible to a viscosity change when exposed to the atmosphere, thus assuring an ease of application and a stable paste formulation when stored in a container. |

Solubilized melanin based compositions supply melanin to skin, scalp and/or hair. The compositions consist of melanin, as an active ingredient, and a substance to solubilize the melanin blended together in a vehicle suitable for topical application. A melanin-based composition applied to the skin provides photoprotection of the human epidermis from exposure to ultraviolet rays. A melanin-based composition applied to wounds in the skin accelerates healing of the wounds. A melanin-based composition applied to the hair and scalp strengthens the hair. |

Color modified melanin compositions are produced by exposure of a natural or synthetic melanin starting material to a color modifying agent under controlled conditions. By treating the melanin starting materials for a preselected time period, melanin products having a desired final color may be obtained. The color modified melanin may be employed in a variety of cosmetic and other topically applied formulations. Prior to incorporation in such formulations, the color modified melanins will be cleaned to remove the color modifying agent and low molecular weight degradation products of the melanin. |

Melanin compositions include a melanin pigment incorporated within polymeric particles, usually within an internal pore network defined by a polymeric particle matrix. The melanin compositions may be produced by in situ oxidation of melanin precursors within the pore network, or by absorption of a melanin pigment in a suitable vehicle or carrier. The melanin compositions are found to display enhanced absorbance of ultraviolet radiation and better cosmetic attributes when compared to melanin pigments which are not incorporated in such a polymeric particle matrix. |

A method of altering skin tissues by application of light energy. Hair coloring is altered by introduction of melanin to the hair and hair follicle. Delivery of melanin is enhance by encapsulation in a liposome. Liposomes are specifically selected for the ability to bind to the tissues of the epidermis. Light energy is applied to release the melanin and assist binding to the targeted tissues. Light energy is preferably provided by one of several laser light sources. The light energy is matched to the absorption of the melanin to reduce absorption and damage to surrounding untargeted skin tissues. |
