Impact of visible light on skin health: The role of antioxidants and free radical quenchers in skin protection

Henry W. Lim et al.

Summary: Until recently, the focus of photobiology has been on the impact of UV radiation on skin health, but the significant effects of visible light (VL) on skin have been underreported. VL can cause erythema in light-skinned individuals and pigmentary changes in dark-skinned individuals. These effects are important in dermatologic diseases and may worsen conditions aggravated by sun exposure. One driving mechanism of VL-induced skin pathologies is the induction of free radicals, which leads to melanogenesis and hyperpigmentation. Clinical studies have shown the effectiveness of topical sunscreen with antioxidants in inhibiting VL-induced erythema and reducing pigmentation. Antioxidants can help prevent the worsening of pigmentary disorders and can be incorporated into photoprotective strategies.

Summary: The study found significant chemical changes in the composition of willowherb during fermentation, resulting in the discovery of a new antioxidant substance, melanoidin. Melanoidin exhibited strong antioxidant properties in in vitro bioassays, and its stability and antioxidant activity were confirmed in a simulated gastrointestinal digestion model.

Expanding the spectrum of polydopamine antioxidant activity by nitroxide conjugation

Fabio Mollica et al.

Summary: Polydopamine (PDA) nanoparticles have been studied for their antioxidant activity, with purified PDA unable to quench alkylperoxyls while copolymerized PDA nanoparticles show good antioxidant activity. Theoretical calculations suggest that PDA has an onion-like structure, with a catechol-rich core and a quinone-represented surface.

Autoxidation vs. antioxidants - the fight for forever

Julian Helberg et al.

Summary: Autoxidation limits the longevity of hydrocarbons and materials by leading to complex mixtures of compounds that alter their physical properties. Antioxidants can inhibit this process by intervening directly in the chain reaction. Understanding the mechanistic considerations of autoxidation is important across various contexts.

Extending photocatalysis to the visible and NIR: the molecular strategy

Alexandra Mavridi-Printezi et al.

Summary: Photocatalysis utilizes light for processes like solar fuel production and environmental purification, but most semiconductor nanoparticles are only efficient in the UV spectrum, leading to the need for sensitization strategies such as using organic molecules and metal complexes for enhancing photoactivity.

Regulation of redox balance using a biocompatible nanoplatform enhances phototherapy efficacy and suppresses tumor metastasis

Qunying Jiang et al.

Summary: The article discusses a highly effective phototherapy method that inhibits tumor growth and metastasis by regulating redox homeostasis using a biocompatible and versatile nanotherapeutic. By eliminating the endogenous ROS scavenging system, the phototherapy is amplified, leading to effective suppression of tumor growth both in vitro and in vivo. This innovative approach may offer a clinically relevant method for cancer treatment.
