Bryan Johnson, a prominent American biohacker and longevity advocate, recently shared his skincare routine on Instagram, claiming it has led to a 9-year skin age reversal. His regimen focuses on cleansing, hydration, and preventing cellular damage, utilizing active ingredients like hyaluronic acid, Skin Care Filter (SCF), and Nicotinamide Mononucleotide (NMN). Johnson's diet emphasizes plant protein, fiber, and polyphenols to combat oxidative stress and inflammation, which are major contributors to skin damage. Experts, including Dr. Aparna Santhanam and Dr. Richa Negi from Kaya Limited, highlight that while Johnson's routine is rigorous, the fundamentals of skincare—such as sun protection, hydration, and a balanced diet—are essential for maintaining skin health. They stress that extreme biohacking is unnecessary; simple daily practices can yield significant benefits. Additionally, they recommend washing the face with cold water in the morning, staying hydrated, and ensuring quality sleep to support skin repair. Overall, the consensus is that protecting the skin from UV damage and adopting a healthy lifestyle are vital for achieving youthful skin.
