Ceriporia lacerata Mycelium Culture Medium as a Novel Anti-Aging Microbial Material for Cosmeceutical Application

Skincare is very critical in preventing aging and skin trouble, which is difficult to recover if progressed. However, the development of effective anti-aging solutions is still on the horizon. The purpose of this study was to evaluate the functional efficacy of Ceriporia lacerata exo-pharmaceutical substance (CLEPS) in view of its use in innovative skin care cosmetics. CLEPS was found to have no cytotoxicity against normal human dermal fibroblasts and B16 melanoma cells in a wide concentration range of 0.05–7 mg/mL. It exhibited a whitening effect by inhibiting melanin synthesis comparable to that of the respective reference compound (arbutin). Notably, CLEPS not only substantially increased collagen (65.4%) and filaggrin synthesis (36%), but also significantly inhibited the activity of collagenase (93.4%), suggesting that CLEPS could prevent skin barrier damage or skin wrinkles. In addition, it showed an excellent anti-inflammatory effect and wound-healing effect. Overall, CLEPS exhibited exceptional anti-aging effects in human skin cells, designating as a potential natural cosmeceutical ingredient.
