If so, which one do you recommend? Thank you.
Answer
Based on the product description for Stabilized Vitamin C (Natural-C Glycol™) Serum, this product is designed as a ready-to-use serum and already contains Phenoxyethanol (0.7%) as a preservative. It is not recommended to mix additional ingredients, including other preservatives, as this can affect the stability of the vitamin C. The product is intended to be used as is, except for potentially adding fragrance (up to 1%) or coloring.
