Abstract
Natural plant oils have been used as a translational alternative to modern medicine. Particularly, virgin coconut oil (VCO) has gained popularity because of its potential benefits in pharmaceutical, nutritional, and cosmetic applications. Cultured coconut extract (CCE) is an alternative end product of VCO, which undergoes a further bacterial fermentation process. This study aimed to investigate the effects of CCE on human skin. We analyzed the expression of skin barrier molecules and collagens after applying CCE on human explanted skin. To evaluate the anti-inflammatory properties of CCE, the expression of inflammatory markers was analyzed after ultraviolet B (UVB) irradiation. The CCE-treated group showed increased expression of cornified cell envelope components, which contribute to protective barrier functions of the stratum corneum. Further, the expression of inflammatory markers was lower in the CCE-treated group after exposure to UVB radiation. These results suggest an anti-inflammatory effect of CCE against UVB irradiation-induced inflammation. Additionally, the CCE-treated group showed increased collagen and hyaluronan synthase-3 expression. In our study, CCE showed a barrier-enhancing effect and anti-inflammatory properties against ex vivo UVB irradiation-induced inflammation. The promising effect of CCE may be attributed to its high levels of polyphenols and fatty acid components.
