Anti-Photoaging Effects of Nanocomposites of Amphiphilic Chitosan/18β-Glycyrrhetinic Acid

Molecules, 2023
Improving the transdermal absorption of weakly soluble drugs for topical use can help to prevent and treat skin photoaging. Nanocrystals of 18β-glycyrrhetinic acid (i.e., NGAs) prepared by high-pressure homogenization and amphiphilic chitosan (ACS) were used to form ANGA composites by electrostatic adsorption, and the optimal ratio of NGA to ACS was 10:

Potential use of medicinal plants from Argentinean highland as agent anti‐photoaging [PDF]

Journal of Cosmetic Dermatology, 2020
AbstractBackgroundThe overexposure to sun ultraviolet (UV) radiation produce photoaging by effect of free radicals on lipid, protein, and nucleic acid or by direct activation of responsible enzymes of cleavage of extracellular matrix components (EMC).AimsTo develop new anti‐photoaging agents, the anti‐aging activity of four “jarillas” standardized ...

Anti-photoaging activities of Sorbaria kirilowii ethanol extract in UVB-damaged cells

Cytotechnology, 2021
Sorbaria kirilowii (Regel) Maxim, a plant found in China, Korea, Japan, and east of Europe, is a common herb used for traditional medicinal purposes. However, its ability to prevent photoaging has not been studied. In this study, we investigated the anti-photoaging functions of an ethanol extract (Sk-EE) of S.

Anti-photoaging effect and mechanism of flexible liposomes co-loaded with apigenin and doxycycline

Biomedicine & Pharmacotherapy, 2023
Prolonged exposure to UV light can lead to photo-ageing of the skin. Therefore, the development and application of anti-photoaging drugs is urgent. In this study, we co-loaded apigenin (Apn) and doxycycline (Doc), a broad-spectrum inhibitor of matrix metalloproteinases (MMPs), into flexible liposomes to exert anti-photoaging effects by combating ...

Preparation and Evaluation of Liposomes and Niosomes Containing Total Ginsenosides for Anti-Photoaging Therapy

Frontiers in Bioengineering and Biotechnology, 2022
Ginsenosides are the principal bioactive compounds of ginseng. Total ginsenosides (GS) contain a variety of saponin monomers, which have potent anti-photoaging activity and improve the skin barrier function. To enhance the efficiency of GS transdermal absorption, GS liposomes (GSLs) and GS niosomes (GSNs) were formulated as delivery vehicles.

Dieckol Isolated from Eisenia bicyclis Ameliorates Wrinkling and Improves Skin Hydration via MAPK/AP-1 and TGF-β/Smad Signaling Pathways in UVB-Irradiated Hairless Mice

Marine Drugs, 2022
Repetitive exposure to ultraviolet B (UVB) is one of the main causes of skin photoaging. We previously reported that dieckol isolated from Eisenia bicyclis extract has potential anti-photoaging effects in UVB-irradiated Hs68 cells.
