Methods For Improving Skin Quality

Abstract

A skin treatment regimen for delivery of a rinse-off personal skin care composition is provided. The rinse-off personal skin care composition includes varying ratios of a lathering agent to a hydrophobic benefit agent. The rinse-off personal skin care composition can be applied to skin of a user in phases over and/or in a treatment cycle. Each of the phases of the treatment cycle can include a ratio of the varying ratios that can be different such as higher or lower than a ratio of adjacent phase.

1 . A method for improving the quality of skin, comprising:
 dispensing from a personal care article a personal care composition that comprises a hydrophobic benefit agent,   applying the personal care composition to a user's skin together with water,   rinsing the personal care composition from the user's skin, wherein a portion of the hydrophobic benefit agent is deposited and remains on the user's skin after rinsing.   repeating the steps of applying and rinsing on at least a once daily basis over a time interval of successive days, the time interval of use sufficient to permit detection of measurable improvement in at least one skin property selected from (i) reduction of visual dryness, a reduction in trans-epidermal water loss, increased skin hydration, increased elastic extension, increased elastic recovery, increased firmness and (ii) reduction in total protein, an increase in the amount of one or more of Keratin 1, Keratin 10 and Keratin 11, and a decrease in cytokine expression.   
     
     
         2 . A method according to  claim 1 , wherein the composition comprises a lathering agent and wherein the article operates to dispense the composition in aliquots, and wherein the ratio of lathering agent to hydrophobic benefit agent varies in successively dispensed aliquots of the composition over the course of dispensing the article contents such that the amount of hydrophobic benefit agent in two or more successive aliquots is different. 
     
     
         3 . The method according to  claim 1 , wherein the measurable improvement is a reduction of visual dryness, wherein the visual dryness reduction is greater than 0.5 dryness unit vs. water control after 3 hours of product application. 
     
     
         4 . The method according to  claim 1 , wherein the measurable improvement is a reduction in trans-epidermal water loss, wherein the reduction of trans-epidermal water loss is greater than 0.2 TEWL unit vs. water control after 3 hours of product application. 
     
     
         5 . The method according to  claim 1 , wherein the measurable improvement is increased skin hydration, wherein the increased skin hydration is greater than one Corneometer Unit vs. water control after 3 hours of product application. 
     
     
         6 . The method according to  claim 1 , wherein the measurable improvement is increased elastic extension, wherein the elastic extension improvement index is greater than 5 after one hour of product application. 
     
     
         7 . The method according to  claim 1 , wherein the measurable improvement is increased elastic recovery, wherein the elastic recovery improvement index is greater than 5 after one hour of product application. 
     
     
         8 . The method according to  claim 1 , wherein the measurable improvement is increased firmness, wherein the skin firmness improvement index is greater than 4 after one of product application. 
     
     
         9 . The method according to  claim 1 , wherein the measurable improvement is reduction in total protein, wherein the total protein improvement index is greater than 10. 
     
     
         10 . The method according to  claim 1 , wherein the measurable improvement is an increase in the amount of one or more of Keratin 1, Keratin 10 and Keratin 11, wherein the Keratin improvement index is greater than 50.
