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.

In 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. Look for L-ascorbic acid at 10–20% in a stable, clinically tested formulation for real results.
  • Consistency and correct use matter. Apply in the morning before sunscreen and avoid pairing with benzoyl peroxide at the same time.
