## Abstract

Compositions comprising a moisturizing agent, a desquamating agent, a mattifying agent and an agent that increases skin luminosity are disclosed herein. The compositions are useful for moisturizing, desquamating, mattifying, and increasing the luminosity in skin of an individual having a Fitzpatrick Skin Type IV, V, or VI. Also disclosed are methods for moisturizing, desquamating, mattifying, and increasing the luminosity in skin, comprising administering to an individual having a Fitzpatrick Skin Type IV, V, or VI, the present compositions.

## Claims

### Claim 1

A method of treating skin of an individual with Fitzpatrick Skin Type IV, V, or VI having: (i) dry skin due to deficient ceramide production; (ii) dead cells and debris on skin surface; (iii) skin that has an oily, shiny appearance due to excessive sebum production; and (iv) an ashy, chalky skin tone comprising administering to the skin of a person having Fitzpatrick Skin Type IV, V, or VI a composition comprising effective amounts of (a) a moisturizing agent that replenishes ceramide on the skin surface and/or enhances ceramide production in skin cells selected from the group consisting of Ceramide 1, Ceramide 2, Ceramide 3, Rosmarinus officinalis extract, rosmarinic acid, ursolic acid, ascorbic acid, esters of ascorbic acid, wheat germ, barley extract, shea butter, and mixtures thereof; and (b) a desquamating agent selected from the group consisting of acetyl glucosamine, Castanea sativa extract, salicylic acid, lactic acid, glycolic acid, maltobionic acid, gluconolactone, Acacia Senegal gum, Salix alba bark extract, yeast extract, glucono-heptono lactone, D-mannose-6-phosphate, polylysine, mushroom extract, galactoarabinan, sodium cholesterol sulfate, N-lactoyl phytosphingosine, forskolin, Coleus barbatus extract, phytic acid, cysteamine lactate, mandelic acid, hydroxylauric acid, and mixtures thereof; and (c) a mattifying agent that reduces sebum production in skin cells and/or absorbs sebum produced by skin cells selected from the group consisting of a silicone elastomer, Serenoa serrulata extract, NDGA, and mixtures thereof; and (d) an agent that increases skin luminosity selected from the group consisting of silica, fluorescent glass, polyvinylalcohol crosspolymer, fluorescent brighteners, disodium distyrylbenzene sulfonate, polydodecaamideaminium triazadiphenylethenesulfate, HDI/PPG/polycaprolactone crosspolymer mica, boron nitride, nylon, and mixtures thereof wherein the composition containing combined amounts of ingredients (a)-(d) is effective to moisturize, desquamate, mattify, and improve skin luminosity in an individual in need thereof.

### Claim 2 (depends on 1)

The method of claim 1 wherein the moisturizing agent acts by replenishing ceramide on the skin surface.

### Claim 3 (depends on 1)

The method of claim 1 wherein the moisturizing agent acts by enhancing ceramide production in skin cells.

### Claim 4 (depends on 1)

The method of claim 1 wherein the desquamating agent is acetyl glucosamine.

### Claim 5 (depends on 1)

The method of claim 1 wherein the mattifying agent reduces sebum production in skin cells.

### Claim 6 (depends on 5)

The method of claim 5 wherein the mattifying agent is a silicone elastomer.

### Claim 7 (depends on 1)

The method of claim 1 wherein the moisturizing agent is Rosmarinus officinalis extract, rosmarinic acid, ursolic acid, or mixtures thereof.

### Claim 8 (depends on 1)

The method of claim 1 wherein the desquamating agent is acetyl glucosamine, Castanea sativa extract, salicylic acid, Salix alba extract or mixtures thereof.

### Claim 9 (depends on 1)

The method of claim 1 wherein the mattifying agent is a Serenoa serrulata extract.

### Claim 10 (depends on 1)

The method of claim 1 wherein the agent that increases skin luminosity is silica, mica, boron nitride, nylon, or mixtures thereof.

### Claim 11 (depends on 1)

The method of claim 1 wherein the moisturizing agent is wheat germ extract, barley extract, Rosmarinus officianalis extract, or mixtures thereof; the mattifying agent is Serenoa serrulata extract; the desquamating agent is Castenea sativa or Salix alba extract; and the luminosity increasing agent is HDI/PPG/polycaprolactone crosspolymer.
