33. A Dermatologist’s Guide to Vitamin C

Do you ever wonder why your dermatologist keeps asking about antioxidants? In this episode, Dr. Elizabeth Rostan walks through the role of topical vitamin C in an anti-aging routine and why it shows up in so many of our recommendations at Charlotte Skin and Laser. She explains how daily sun exposure, pollution, and even normal metabolism create oxidative stress that breaks down collagen and accelerates visible aging. You’ll hear what makes a vitamin C actually effective, how to use it in your routine, and why consistency over time is what protects your skin and keeps it looking healthy for years to come.Products mentioned:SkinCeuticals CE FerulicSkinCeuticals Phloretin CFSkinCeuticals Silymarin CFSkinBetter Science antioxidant productsCharlotte Skin & Laser Triple Defense Antioxidant CreamCharlotte Skin & Laser Triple Defense Antioxidant SerumIn this episode you’ll learn:Vitamin C is prevention, not a quick fix. Its biggest impact happens over time by protecting collagen, elastin, and DNA from daily damage.Not all vitamin C is created equal.
