The color of vitamin C, specifically in serum form, can vary from clear to light yellow or light brown.
Understanding Vitamin C Color Variation
It's important to note that the color of a vitamin C serum can change due to oxidation, which is a natural process. Factors contributing to oxidation include:
- Exposure to air
- Exposure to light
- Exposure to heat
Even with a change in color, like turning a bit yellow or amber, the serum is still generally considered effective and the active ingredients remain potent according to What Does it Mean if My Antioxidant Serum is Gold or Amber in Color?.
Vitamin C Color in Different Forms
While we've focused on serum form, remember that vitamin C, also known as ascorbic acid, is often a white powder in its pure state. However, when dissolved into other solutions, the color will depend on the formulation and if oxidation has occurred.
