Abstract

The present invention discloses a plant extract-mediated drug transdermal introducing system and a transdermal method thereof. The plant extract-mediated drug transdermal introducing system comprises a transdermal introducing agent prepared from at least one plant extract, and biological macromolecules or a preparation thereof. The transdermal method includes: using the transdermal introducing agent to promote penetration, then performing transdermal penetration for the biological macromolecules or the preparation thereof; or mixing the biological macromolecules or the preparation thereof with the transdermal introducing agent to prepare a composite formula preparation for transdermal penetration. The present invention also provides the application of the plant extract-mediated drug transdermal introducing system or the transdermal method thereof in the preparation of skin health products. Preparing skin health products by the system, the biological macromolecules can penetrate into the skin to achieve a better therapeutic effect.

Description

technical field [0001] The invention relates to a drug transdermal delivery system mediated by plant extracts and a transdermal method thereof. Background technique [0002] Abnormal local skin pigmentation caused by excessive and uneven secretion of melanin will form spots or plaques on the face and back of the hands, such as: pregnancy spots, acne marks, birthmarks, moles, freckles, sun spots and age spots. [0003] For centuries, people have used a variety of topical creams to lighten the skin and reduce hyperpigmentation. In recent years, people have used hydroquinone (HQ), magnesium L-ascorbic acid-2-phosphate (MAP), hydroquinone monomethyl ether, N-acetyl-4-S-cysteinephenol and arbutin and other chemical substances to remove pigmentation, but these substances will cause side effects such as local depigmentation, dermatitis, and even canceration and brown and yellow disease, forcing people to look for alternatives (Parvez S et al., Phytother Res.2006, 20 (11): 921-34)...
