Neurocosmetics and Longevity: Shaping the Future of Well-Being

Cosmetic science is undergoing a paradigm shift, moving beyond superficial and narrowly defined anti-aging targets toward holistic and longer-term interventions designed as an integral part of daily lifelong self-care, and addressing the fundamental biological processes underlying skin health and beauty together with overall user well-being in the wider context of longevity. Neurocosmetics, positioned at the critical interface between the skin and the nervous system, represents a unique opportunity as a tool for such holistic interventions, and has been making remarkable progress of its own in recent years. We explain the reframing around longevity and briefly review the biological foundations of neurocosmetics, centering on the bidirectional skin-brain communication network through which topical neurocosmetic interventions may benefit both dermatological outcomes and psychophysiological states, improving visible skin appearance while also promoting positive psychological effects such as stress reduction, mood enhancement, and improved sleep quality. We explore advanced measurement tools, including functional magnetic resonance imaging (fMRI), electroencephalography (EEG), and artificial intelligence that have enabled objective assessment of holistic conscious and unconscious neurocosmetic effects, progressing the field beyond superficial or subjective evaluations. We pause to address critical ethical, safety, and regulatory considerations that this field will need to observe, in particular around avoiding the trap of addiction-promoting product development or promotion strategies, and ensuring the transparency that informed consumer choice requires. We review holistic formulation approaches including tactile perception, olfactory stimulation, and multisensory integration, and active ingredients including neuropeptides and neuroactive botanicals. Chronobiology in skin health is discussed, as well as the burgeoning understanding of the gut-skin-brain axis as an intervention pathway. This review aims to provides a framework for positioning neurocosmetics as a scientifically grounded approach to promoting holistic well-being in longevity.
