Cosmetic compositions and methods for their use in firming skin

Abstract

A method of reducing the appearance of loose, sagging, or flaccid skin is disclosed. The method can include topically applying to skin in need thereof a composition that includes 0.0001 wt. % to 10 wt. % Argania spinosa kernel extract, 0.0001 wt. % to 10 wt. % dill extract, 0.0001 wt. % to 10 wt. % Myrciaria dubia fruit extract, and 0.0001 wt. % to 10 wt. % Croton lechleri extract or Morus alba fruit extract. Topical application of the composition can increase elastin expression, increase elastin secretion, or increase elastin fiber formation in the skin in need thereof, and the appearance of loose, sagging, or flaccid skin can be reduced.

1 . A method of reducing the appearance of loose, sagging, or flaccid skin, the method comprising topically applying to skin in need thereof a composition comprising 0.0001 wt. % to 10 wt. %  Argania spinosa  kernel extract, 0.0001 wt. % to 10 wt. % dill extract, 0.0001 wt. % to 10 wt. %  Myrciaria dubia  fruit extract, and 0.0001 wt. % to 10 wt. %  Croton lechleri  extract or  Morus alba  fruit extract, wherein topical application of the composition increases elastin expression, increases elastin secretion, or increases elastin fiber formation in the skin in need thereof, and wherein the appearance of loose, sagging, or flaccid skin is reduced. 
     
     
         2 . The method of  claim 1 , wherein topical application of the composition increases skin elasticity in the skin in need thereof. 
     
     
         3 . The method of  claim 1 , wherein topical application of the composition increases elastin expression in the skin in need thereof. 
     
     
         4 . The method of  claim 1 , wherein topical application of the composition increases elastin expression by at least 75% in the skin in need thereof as compared to skin which has not been treated with the composition. 
     
     
         5 . The method of  claim 1 , wherein topical application of the composition increases collagen expression in the skin in need thereof. 
     
     
         6 . The method of  claim 1 , wherein topical application of the composition increases laminin or fibronectin production in the skin in need thereof. 
     
     
         7 . The method of  claim 1 , wherein topical application of the composition increases fibulin-5 production in the skin in need thereof. 
     
     
         8 . The method of  claim 1 , wherein the skin in need thereof is skin of a jowl. 
     
     
         9 . The method of  claim 1 , wherein the skin in need thereof is neck skin. 
     
     
         10 . The method of  claim 1 , wherein the skin in need thereof is facial skin. 
     
     
         11 . The method of  claim 1 , wherein the composition is an emulsion. 
     
     
         12 . The method of  claim 11 , wherein the emulsion is an oil-in-water emulsion. 
     
     
         13 . The method of  claim 1 , wherein the composition is a gel. 
     
     
         14 . The method of  claim 1 , wherein the composition is an aqueous solution. 
     
     
         15 . The method of  claim 1 , wherein the composition is a hydro-alcoholic solution. 
     
     
         16 . The method of  claim 1 , wherein each extract is an aqueous extract, an alcoholic extract, or an aqueous-alcoholic extract. 
     
     
         17 . The method of  claim 1 , wherein the composition is applied daily. 
     
     
         18 . The method of  claim 1 , wherein the composition comprises 0.0001 wt. % to 10 wt. %  Croton lechleri  extract. 
     
     
         19 . The method of  claim 1 , wherein the composition comprises 0.0001 wt. % to 10 wt. %  Morus alba  fruit extract. 
     
     
         20 . The method of  claim 1 , wherein the composition comprises 0.1 wt. % to 5 wt. %  Argania spinosa  kernel extract, 0.1 wt. % to 5 wt. % dill extract, 0.1 wt. % to 5 wt. %  Myrciaria dubia  fruit extract, and 0.1 wt. % to 5 wt. %  Croton lechleri  extract or  Morus alba  fruit extract.
