Abstract: A composition for topical administration to an epithelium is disclosed. The composition comprises a deconstructed matrisome including one or more enzymatically fragmented peptides derived from biological tissue. The composition further comprises one or more pharmaceutically acceptable or cosmetically acceptable excipients. The deconstructed matrisome may be fragmented through degradation by one or more enzymes to produce the one or more peptides. The one or more peptides may be configured to retain cell signaling ability, thereby promoting one or more of tissue homeostasis, tissue repair, and tissue regeneration. The composition may be used to treat a tissue such as skin tissue exhibiting scarring, acne, eczema, psoriasis, and other skin conditions.
