Beauty tech is taking anti-aging to a cellular level. Emerging innovations now blend AI, biotechnology, and nanotech for hyper-personalised skincare solutions. Products include DNA-coded serums tailored to individual genetics, wearable nanobots managing hormone and skincare delivery in real-time, and exosome-based treatments to stimulate skin regeneration and reduce inflammation. Novel injectables like GLP‑1 and microbiome-targeted supplements recalibrate metabolism. Leading beauty firms—from Estée Lauder to niche biotech startups—are investing heavily in these precision treatments, which aim to transform aging care from surface sensitivity to deep biological repair.
