“…It is believed that considerable preventive effects of whey peptides against chronic UVB radiation-induced skin ageing in melanin-possessing male hairless mice may be attributed to their antioxidant activities and immune functions (through which the increases in the expression of matrix metalloproteinase (MMP), vascular endothelial growth factor (VEGF), Ki-67-and 8-hydroxy-2 0 -deoxyguanosine (8-OHdG)-positive cells were prevented) (Kimura et al, 2014). The contribution of extracellular peptides of UV-irradiated yeast Saccharomyces cerevisiae, Kluyveromyces fragilis and Candida utilis to the protection against UV radiation through antistress mechanisms was also reported (Vorob'eva et al, 2011). A super potent melanotropic peptide, melanotan-1 (MT-1, or [Nle4-D-Phe7] alpha-melanocyte-stimulating hormone), was found safe to be included as part of the UVB light or sunlight treatment and can act synergistically in the tanning response to light (Dorr et al, 2004).…”

Summary Appropriate exposure to sun is beneficial to humans and living organisms. However, excessive exposure to ultraviolet (UV) radiation can lead to photoageing, severe health risks and even death. Nowadays, the health risks of excess UV exposure have greatly increased due to the significant changes of global climate and human lifestyle as well as the thinning of the stratospheric ozone (a natural and effective filter for solar UV radiation). Therefore, protecting against UV radiation‐induced damage is a serious challenge. Research needs to address the understanding of the mechanisms underlying the UV‐induced damages and also explore the potential use of natural substances to combat the harm caused by UV radiation. Plant‐based substances have been found to exert significant protective effects against UV radiation. This review explores the most recent hypothesis of natural bioactive compounds (such as flavones, peptides, polysaccharides and terpenoids) as potential protective agents against UV radiation. The similarities and differences in UV photoprotective mechanisms among these different classes of compounds are also discussed.
