Skin exposure to ultraviolet B (UVB) irradiation has increased significantly in recent years due to ozone depletion, and it represents the main cause of many skin diseases. Hesperidin methyl chalcone (HMC) is a compound used to treat vascular diseases that has demonstrated anti-inflammatory activities in pre-clinical studies. Herein, we tested the antioxidant activity of HMC in cell free systems and the in vivo effects of a stable topical formulation containing HMC in a mouse model of skin oxidative stress and inflammation induced by UVB irradiation.

The purpose of this study was to evaluate the physicochemical and functional antioxidant stability of NGN containing formulations, and the effects of selected NGN containing formulation on UVB irradiation-induced skin inflammation and oxidative damage in hairless mice. NGN presented ferric reducing power, ability to scavenge 2,2'-azinobis (3-ethylbenzothiazoline- 6-sulfonic acid) (ABTS) and hydroxyl radical, and inhibited iron-independent and dependent lipid peroxidation.

Naringenin (1) has been reported to have anti-inflammatory and antioxidant properties, but its effects and mechanisms on UVB irradiation-induced inflammation and oxidative stress are still not known. Thus, the present study aimed to investigate the potential of naringenin to mitigate UVB irradiation-induced inflammation and oxidative damage in the skin of hairless mice.

Thus, the purpose of this study was to evaluate the effects of systemic administration of HMC in skin oxidative stress and inflammation induced by UVB irradiation. To induce skin damage, hairless mice were exposed to an acute UVB irradiation dose of 4.
