Abstract
BACKGROUND
Collagen is a major component of the extracellular matrix that supports the epidermal layers of the skin; thus, many strategies have been made to enhance the topical delivery of collagen for antiaging purposes. In addition, our previous study indicated that liposome can help the penetration of active ingredients into the skin.
AIMS
To produce stable collagen-encapsulated liposomes to improve the topical delivery of collagen.
METHODS
Collagen-encapsulated liposomes were fabricated using high-pressure homogenization method. The colloidal stability and adhesion ability were confirmed using dynamic light scattering, and spectrofluorophotometer, respectively. Keratinocyte differentiations of 3D skin before and after treatment with collagen-encapsulated liposomes were confirmed by real-time PCR.
RESULTS
In comparison with native collagen, collagen-encapsulated liposomes enhanced collagen retention in artificial membranes by twofold, even after repeated washings with water. In addition, real-time PCR results indicated that 3D skin treated with collagen-encapsulated liposomes exhibited higher levels of collagen, keratin, and involucrin, even after ethanol treatment.
CONCLUSION
Liposomes could serve as efficient delivery vehicles for collagen, thereby enhancing its antiaging effects.
