Sun, pollution, and even your phone screen constantly stress your skin. At the Science of Skin Summit, Dr. Patti Farris broke down what actually works to defend against that daily onslaught—and why vitamin C remains the MVP when formulated and used correctly. We translate the science into plain English, explaining how free radicals damage collagen and DNA, how oxidative stress shows up as wrinkles and brown spots, and why topical vitamin C outperforms diet alone by directly saturating skin and complementing SPF against visible and infrared light.

Dr. Farris also walks through how to pick the right formula: L-ascorbic acid for potency, THD ascorbate for sensitive skin, and the powerhouse combo of vitamins C + E + ferulic acid for all-day antioxidant defense. Expect clear, practical takeaways—a morning routine that starts with antioxidant serum, ends with mineral sunscreen, and shifts your mindset from “anti-aging” to everyday skin resilience.
