Vitamin C: Form, Function and the Barrier
Use Left/Right to seek, Home/End to jump to start or end. Hold shift to jump forward or backward.
Vitamin C is one of the most used ingredients in skincare. It’s associated with brightness, collagen, and protection and often treated as non-negotiable.
In this episode, we slow the conversation down to look at how vitamin C actually behaves, how form, stability, pH, packaging, and delivery systems shape the results and benefits. We explore the difference between traditional ascorbic acid and oil-soluble alternatives and the role of whole vitamin-C–rich ingredients.
This is a deeper look at a familiar ingredient, through the lens of barrier health, repair, and long-term skin resilience.
