The present invention relates to topical glycosaminoglycan compositions, particularly hyaluronan compositions, that facilitate the penetration of modified glycosaminoglycans through the skin barrier into the epidermal and dermal layers of the skin, thereby allowing for the dermal administration of a glycosaminoglycan, such as hyaluronan, without requiring an injection. Through their ability to deliver hyaluronan to the epidermal and dermal layers, the present formulations are therefore suitable for use in dermal rejuvenation, enhancement, hyaluronan replenishment and protection therapy. The glycosaminoglycan compositions are also useful as delivery devices to facilitate the dermal and transdermal delivery of cosmetically and pharmaceutically active substances, including pharmaceuticals, polypeptides, proteins and similarly sized biomacromolecules, through the skin barrier.
A non-particulate glycosaminoglycan composition comprising a glycosaminoglycan modified through the covalent linkage of a lipid moiety to about 1-15% of the repeating disaccharide monomer units of the glycosaminoglycan wherein:
