  The invention relates generally to intradermal, transdermal, and/or transmembrane delivery of biologically active substances in the epidermis and/or through the skin, sub-dermal tissues, blood vessels and cellular membranes without causing damage to the cellular surface, tissue or membrane. The biologically active substances may have a molecular weight no less than about 5.8 kDa to about 2,500 kDa, such as Hyaluronic Acid (HA). The biologically active substances may be deposited in a dermal patch containing a red algae polysaccharide-based matrix, wherein the red algae polysaccharide is an extract of Chondrus crispus at 2% by weight of the dermal patch. The invention provides systems and methods for enhanced intradermal, transdermal, and/or transmembrane delivery of such biologically active substances using pulsed incoherent light. The invention further provides a device for the application of the pulsed incoherent light to cellular surfaces and membranes using those compositions and methods.
