I  am not using Ascorbic acid, Tetrahexyldecyl Acorbate is  oil-soluble Vitamin C.
I wrote this post asking for advice if adding those vitamins will increase effectiveness of the product.

I am thinking of preparing my own the cream base using it for different purposes. Just wanted to confirm if I add those actives, botanical extracts, niacinamide, proteins, ceramides, etc will they still perform as they should after adding them to the cold cream?

Ok, here I am formulating a face cream for a mature, dry skin. I am trying to stick to the “natural” ingredients  as much as possible. This product feels good on the face, but I would like to add more antioxidants. 
my formulation contains: green tea extract, glycerin, honeyquat, silk proteins, oat proteins, Panthenol, niacamide, n-acetylglucosamide, hyialuric acid, borage oil, squalane, cocoa, Olivem 1000, cetyl alcohol, vit E, optiphen ND,

Hmm, thank johnb. So which antioxidant is on the top of your list? I appreciate if you can share… Tetrahexyldecyl ascorbate, ascorbyl palmitate? Idebenone or Astaxanthin perhaps? I am beginning Formulator so please advise me, which of antioxidants would be pretty easy to use and quite stable in my formulation.
