In neuronal senescence model studies, the active ingredient of the product can cross the blood-brain barrier (and act directly on neurons in vitro), increase NAD+ levels in nerve cells, protect mitochondrial function, reduce neuronal apoptosis, and promote the synthesis and release of neurotransmitters (such as dopamine and acetylcholine), thereby improving signal transduction in nerve cells
Results can vary based on individual skin types and conditions
