Pour into a colored glass dropper bottle. It is important to use colored glass because Vitamin C oxidizes fast!
This serum has a shorter shelf life than most cosmetics because the Vitamin C oxidizes in the water over time. So, make it pretty often. I find that I make it about every 1-2 weeks.
Notes
Note: You might find it tingles when applied, this is normal. If it burns, then make a weaker dilution or use it every other day.I apply Vitamin C Serum to my face every morning when I wake up and every night before bed. It can be applied morning and night!
