       9 . The cosmetic system of  claim 8  wherein the at least one wax particle maintains at least some of its size and shape through processing and application onto lashes.  
   
   
       10 . The cosmetic system of  claim 1  wherein the primary particle is select from the group consisting of thermoplastic polymeric particles, thermoset polymeric particles, and mixtures thereof.  
   
   
       11 . The cosmetic system of  claim 10  wherein the primary particle has a glass transition temperature (Tg) of from about −100° C. to about 300° C.  
   
   
       12 . The cosmetic system of  claim 1  wherein the primary particle comprises at least one plasticizer.  
   
   
       13 . The cosmetic system of  claim 1  wherein the primary particle is an inorganic material.  
   
   
       14 . The cosmetic system of  claim 7  wherein the primary particle is structured to absorb a liquid.  
   
   
       15 . The cosmetic system of  claim 1  wherein the cosmetic composition further comprises at least one secondary particle that is from about 1 micron to about 49 microns in equivalent diameter and is structured to pack between the primary particles in the cosmetic composition.  
   
   
       16 . The cosmetic system of  claim 15  wherein at least one secondary particle is selected from shapes consisting of spheres, ovals, irregular, platelets, and mixtures thereof.  
   
   
       17 . The cosmetic system of  claim 16  wherein the secondary particles are platelets having a dimension of at least about 10 microns to about 200 microns.  
   
   
       18 . The cosmetic system of  claim 15  wherein the ratio of a combined volume of primary and secondary particles to a volume of the total composition is from about 1:20 to about 10:1.  
   
   
       19 . The cosmetic system of  claim 15  wherein the primary and secondary particles are coated.  
   
   
       20 . The cosmetic system of  claim 1  wherein the composition is selected from the group consisting of anhydrous, oil-in-water emulsions, water-in-oil emulsions, water-in-silicone emulsions, silicone-in-water emulsions, multiple emulsions and mixtures thereof.  
   
   
       21 . The cosmetic system of  claim 19  wherein at least some of the primary particles are structured to swell to at least about 5 microns in equivalent diameter.  
   
   
       22 . The cosmetic system of  claim 21  wherein at least some particles are swelled by a solvent that is applied as a topcoat.  
   
   
       23 . The cosmetic system of  claim 1  wherein the cosmetic system is packaged as a product selected from unitary packaging and separate packaging.  
   
   
       24 . A cosmetic system comprising, in combination: 
 (a) a cosmetic applicator comprising a substantially longitudinal stem having a major axis A and a plurality of protrusions extending therefrom, wherein each protrusion is spaced from one another at a distance R along the base of the stem;    (b) a cosmetic composition comprising primary particles that are at least about 5 microns in equivalent diameter in a dermatologically acceptable carrier; and    (c) a cosmetic composition comprising primary particles that are at least about 5 microns in equivalent diameter    wherein the system is structured such that (c) is applied as a secondary coat to the combination of (a) and (b).
