Matrix hyaluronic acid and bilayer poly-hydroxyethyl methacrylate-hyaluronic acid films as potential ocular drug delivery platforms

This study aimed to design hydrogel based films comprising hyaluronic acid (HA) to overcome limitations of currently used eye drops. Timolol-loaded crosslinked (X2) HA-based and bilayer (B2) (pHEMA/PVP-HA-based layers) films […]

Compound K suppresses epidermal aging induced by IL-17A treatment and UVB irradiation

We evaluated the anti-accelerated epidermal skin aging effects of compound K (CK) on keratinocytes using IL-17A and ultraviolet B. CK restored epidermal functions and reduced the induction of pro-inflammatory cytokines […]

Nicotinamide Metabolism Modulates the Proliferation/Differentiation Balance and Senescence of Human Primary Keratinocytes

Nicotinamide (NAM) is the main precursor of nicotinamide adenine dinucleotide (NAD+), a coenzyme essential for DNA repair, glycolysis, and oxidative phosphorylation. NAM has anti-aging activity on human skin, but the […]

Senescent human melanocytes drive skin ageing via paracrine telomere dysfunction

Cellular senescence has been shown to contribute to skin ageing. However, the role of melanocytes in the process is understudied. Our data show that melanocytes are the only epidermal cell […]
