The combined effect of commercial tilapia collagen peptides and antioxidants against UV-induced skin photoaging in mice

Abstract

A proposed mechanism for a mixture of collagen peptides (CP) and natural antioxidants against UV-induced photoaging.

Clinical Efficacy in Skin Hydration and Reducing Wrinkles of Nanoemulsions Containing Macadamia integrifolia Seed Oil

“…Antioxidants play a vital role in skin rejuvenation by neutralizing harmful free radicals and reducing oxidative damage to skin cells [ 16 , 17 ]. Antioxidants have been reported to protect the skin against UV-induced damage [ 18 ], reduce collagen degradation [ 19 ], reduce inflammation [ 19 ], and thereby enhance the skin’s barrier function, resulting in more skin vitality and youthful-looking skin, as well as diminished visible signs of aging and maintenance. Hyaluronic acid has both structural and signaling roles [ 20 ].…”

“…Antioxidants play a vital role in skin rejuvenation by neutralizing harmful free radicals and reducing oxidative damage to skin cells [16,17]. Antioxidants have been reported to protect the skin against UV-induced damage [18], reduce collagen degradation [19], reduce inflammation [19], and thereby enhance the skin's barrier function, resulting in more skin vitality and youthful-looking skin, as well as Oxidative stress is a primary contributor to skin aging, leading to the formation of wrinkles and other signs of aging [15]. Antioxidants play a vital role in skin rejuvenation by neutralizing harmful free radicals and reducing oxidative damage to skin cells [16,17].…”

The extract from Portulaca oleracea L. rehabilitates skin photoaging via adjusting miR-138-5p/Sirt1-mediated inflammation and oxidative stress

“…Triethanolamine was used to adjust the pH until the gel became transparent. Before UV irradiation, 0.2 mL of purslane extract (VE) gel was applied to the shaved area of the mice for 0.5 h, three times a week, for eight weeks [ 33 , 34 ].…”

Moringia oleifera Lam. seeds isothiocyanate against skin photoaging by regulating p38MAPK-dependent autophagy signalling pathway

“…At present, VC and retinoic acid are often used in the market to treat skin aging [18,19] , but excessive retinoic acid may lead to osteoporosis [19] . Vc is considered to be an important antioxidant that protects the skin by releasing solvated electrons during singlet excitation and neutralizing ROS generated when exposed to sunlight.…”

“…Vc is considered to be an important antioxidant that protects the skin by releasing solvated electrons during singlet excitation and neutralizing ROS generated when exposed to sunlight. In biological systems, it reduces oxygen and nitrogen free radicals through redox reactions, thereby delaying the ageing process [18] . Vc has multiple functions in the skin, such as collagen synthesis, decolorization and antioxidant activity.…”
