Our Vitamin C Serum contains a 5% pure Vitamin C solution. We use a form of Vitamin C that is very concentrated thus making a small amount more effective. Because of this high concentration when using the Vitamin C Serum, "less-is-more". We have found that using 1-2 drops is sufficient for the application.
When you start using this product we highly suggest applying less product as this should allow for the skin to acclimate to the high concentration of Vitamin C.
We always suggest doing a patch test before using or introducing any products into your skincare routine.
