Peptides for skin rejuvenation and methods of using the same
The invention provides compositions for stimulating the formation of one or more extracellular matrix components that contain a lipoaminoacid derivative of the tripeptide carnosine such as N-Octanoyl Carnosine. Also provided are compositions containing N-Octanoyl Carnosine in combination with selected tripeptide and/or tetrapeptides as well as pharmaceutical and/or cosmetic compositions containing such compositions. The invention further provides methods of using the compositions and compositions of the invention to treat, alleviate, and/or ameliorate a symptom, condition, disorder, or disease of the skin or mucosa, wherein the symptom, condition, disorder, or disease is associated with changes in extracellular matrix components.
1. A method of improving or rejuvenating the appearance of skin in a patient in need thereof comprising administering an effective amount of a composition for stimulating the formation of collagen III in skin or mucosa to the patient, wherein the composition comprises N-octanoyl carnosine and N-palmitoyl-GHK and one or more carriers or excipients suitable for topical administration or subcutaneous administration, and wherein the composition stimulates the formation of collagen III to a higher degree than the formation of collagen I.
2. The method of claim 1 , wherein the method results in improving the appearance of aged skin.
3. The method of claim 1 , wherein the composition is administered to the patient in the form of a cosmetic, a personal care product, a feminine care product, a hygiene product, a dermatology product, a pharmaceutical preparation, a medicament, or any combination thereof.
4. The method of claim 1 , wherein the composition is administered topically to the skin or mucosa of the patient.
5. The method of claim 1 , wherein the composition is administered subcutaneously to the patient.
6. The method of claim 1 , wherein the composition stimulates the formation of collagen Ill by at least 120% and the formation of collagen I by at least 38%.
7. The method of claim 1 , wherein the composition is administered to the face of the patient.
8. The method of claim 1 , wherein the composition further comprises the tetra-peptide GEKG (SEQ ID NO:1), and wherein the weight ratio of N-octanoyl carnosine:N-palmitoyl-GHK:GEKG (SEQ ID NO:1) is 4:1:5.
9. The method of claim 8 , wherein the composition further stimulates the formation of hyaluronic acid.
10. The method of claim 9 , wherein the combination of active ingredients N-octanoyl carnosine, N-palmitoyl-GHK, and GEKG (SEQ ID NO:1) stimulates the production of extracellular matrix components in skin or epithelial cells to a greater degree than any one or two of the active ingredients alone.
11. The method of claim 1 , wherein the composition comprises between about 0.0001% to 10% per weight of N-octanoyl carnosine.
12. The method of claim 1 , wherein the composition comprises about 0.004% per weight of N-octanoyl carnosine; and further comprises about 0.001% per weight of N-palmitoyl-GHK, and about 0.005% per weight of GEKG (SEQ ID NO:1), and one or more acceptable carriers or excipients suitable for topical application in humans on skin, aged skin, damaged skin, skin after cosmetic and dermatological procedures, wounded skin, atrophic skin, atrophic mucosa, atrophic vulva, and/or atrophic vagina.
13. The method of claim 1 , wherein the composition is a pharmaceutical composition and further comprises one or more pharmaceutically acceptable carriers.
14. The method of claim 1 , wherein the composition is a cosmetic composition and further comprises one or more cosmetically acceptable carriers.
15. The method of claim 1 , wherein the composition further stimulates the formation of elastin, laminin, hyaluronan synthase 2, fibrillin 1, and/or heparan sulfate proteoglycan.
16. The method of claim 1 , wherein the method further results in one or more of the following: improving the state of aged skin, reducing the signs of aging, reducing scarring of damaged skin, restoring damaged skin, enhancing the restoration of skin after cosmetic and dermatological procedures, restoring aging vulvar vaginal tissue, reducing scarring of damaged skin, or restoring damaged skin.
17. The method of claim 1 , wherein the composition is administered to
a) one or more areas of skin selected from the group consisting of neck, neckline, decollete, scalp, hand, palm, arm, leg, foot, sole, chest, breast, back, abdomen, buttock, vulva, penis, scrotum, and anus; or
b) one or more mucosal areas selected from the group consisting of eye, mouth, nose, nipples, vulva, vagina, vaginal introitus, penis, and rectum.
