Description:
[0001]    This application claims priority of U.S. Provisional Patent Application Ser. No. 61/656,131, filed Jun. 6, 2012. 
     
    
     FIELD OF INVENTION 
       [0002]    Lips are the most susceptible to dryness and cracking of any part of the skin. Topical lip balm products such as the present invention protect and help restore lips from the effect of dryness and cracking. 
       BACKGROUND OF THE INVENTION 
       [0003]    Lips are continuously moving and subjected to repeated stress (ultraviolet radiation, dry air, etc.). The lip area is fragile by nature and needs protection in order to overcome the deficiency, or gradual decline of dermal macromolecules. Naturally dry through the fineness of the barrier and absence of moisturizing and lipid restoring glands, the vermilion of the lips is continuously subjected to drying. The mechanisms resulting in moisturization have to be strengthened to limit chapping and cracking. The vermilion of the lips is devoid of sebaceous and sweats glands. Unlike the skin, the lips have no hydrolipid protective film. 
         [0004]    Aging of the lip zone is characterized by increased water loss, loss of volume and changes in syntheses which gives rise to a decrease in dermal density. The progressive reduction in collagens accompanied by the fall in collagen I and collagen III levels is largely responsible for the gradual loss of dermal thickness and hence the decrease in lip volume. 
       SUMMARY OF THE INVENTION 
       [0005]    This invention is an improved lip balm product, comprising hyaluronic acid, sodium hyaluronate,  Portulaca  extract, boswellic acids, cosmetic wax, honeysuckle, shea butter, and fragrance.

         [0007]    A component of the invented lip balm product is dehydrated microspheres of marine collagen and glycosaminoglycans. These microspheres have the capacity to rehydrate in the presence of water and regain their initial volume. While dehydrated, the microspheres are small enough to penetrate crevices in lips. The microspheres increase in size through absorption of moisture in the lips, which causes a smoothing of the lip surface. The microspheres are slowly degraded by enzymes in the lip, which allows the microspheres to release the moisture initially absorbed from the lips, returning the moisture to the lips. The microspheres are preferably comprised of marine atelocollagen and marine chrondroitin sulfate, as disclosed in U.S. Pat. Nos. 5,395,620, 5,420,248 and 5,622,656, as well as non-US counterparts. 
         [0008]    Another component of the invented lip balm product is a synthetic ceramide and anti-irritant compound. Skin tissue has a protective layer referred to as a lipid bilayer, which helps bind corneocytes to protect skin tissue from external damage. The lipid bilayer is itself comprised of ceramides, fatty acids and cholesterol. Skin tissue with decreased ceramide levels have been shown to suffer a variety of damage, but unlike fatty acids and cholesterol, ceramides cannot be easily replaced. A synthetic ceramide can provide similar protection to naturally occurring ceramides. The synthetic ceramide combines synthetic ceramide with an anti-inflammatory known as alpha-Bisabolol, as well as Phytosterol and Stearic acid, to supplement the lipid bilayer of skin tissue. 
         [0009]    A further component of the invented lip balm product are small particles of sodium hyaluronate. Skin tissue, including lip tissue, contains hyaluronic acid, a natural polymer. Hyaluronic acid maintains tissue hydration and helps retain water within the skin tissue. Sodium hyaluronate particles penetrate the lip tissue, and increase in size by absorbing moisture from the lip tissue as well as external moisture. The swelling of the sodium hyaluronate particles increase the volume of the lip tissue, reducing wrinkles and plumping the lips. Preferably, the sodium hyaluronate particles are delivered, in an oil-based suspension, to prevent particle expansion before penetration into the lip tissue. 
         [0010]    Yet another component of the invented lip balm product is a compound of an extract of the  Portuluca pilosa  plant with a peptide. The  Portuluca pilosa  plant, also known as “Kiss-Me-Quick,” is part of the purslane family of edible plants.” This component combines an extract of the  Poratuluca pilosa  plant with a matrikin-mimetic peptide for the purposes of restoring lip volume and firmness. 
         [0011]    While certain novel features of the present invention have been shown and described, it will be understood that various omissions, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing from the spirit of the invention.
