       6 . An oil-in-water emulsion or silicone-in-water emulsion composition according to  claim 5 , wherein the oil phase or the silicone phase comprises less than about 20% by weight of the total composition. 
   
   
       7 . An oil-in-water emulsion or silicone-in-water emulsion composition according to  claim 6 , wherein the oil phase or the silicone phase comprises less than about 15% by weight of the total composition. 
   
   
       8 . An oil-in-water emulsion or silicone-in-water emulsion composition according to  claim 6 , wherein the oil phase or the silicone phase comprises less than about 10% by weight of the total composition. 
   
   
       9 . A topically-applied personal care or dermatologic composition of  claim 1  which is anhydrous. 
   
   
       10 . A topically-applied personal care or dermatologic composition of  claim 1  further comprising further comprising at least one colorant. 
   
   
       11 . A topically-applied personal care or dermatologic composition of  claim 1  that helps to reduce the appearance of and/or prevent a skin condition selected from the group consisting of fine lines, wrinkles, age spots, sallowness, blotchiness, redness, dark circles under the eyes or skin oiliness. 
   
   
       12 . A topically-applied personal care or dermatologic composition of  claim 1  that helps to reduce transepidermal water loss, improve skin retention of moisture or improve skin elasticity.
