In this fascinating episode of Beauty Bytes, I am joined by Dr. Kay Linker, a brilliant neuroscientist, aging researcher, and the founder of Aionion, the first longevity-focused supplement brand created specifically for women. We dive deep into what actually happens to our brains as we age—hint: it's not just the neurons, but the support cells like astrocytes and microglia that change the most. Dr. Linker breaks down the "longevity gap" for women, explaining how the steep drop-off in estrogen during perimenopause and menopause severely impacts dopamine, serotonin, and mitochondrial biogenesis, meaning women need to start preparing for brain aging in their 30s. We also tackle modern threats to brain health, from how scrolling on social media destroys our attention span via random dopamine rewards, to the terrifying reality of microplastics accumulating in the brain
