Dr Jo left a message to me, asking me to check out this site about Vitamin C and how to make our own Vitamin C serum. Thanks Dr Jo!
I tried on Vitamin C before, just pure Vitamin C on my face when I was pregnant with Isabelle. I had some skin problem due to pregnancy hormone. I couldn’t put on anything put that Vitamin C and some treatment serum.
She got a point that about this……
Do not buy vitamin C preparations that are tinted yellow or orange
The second problem with using a colour test is that many vitamin C serums are tinted and you will not be not be able to detect if it is oxidised by visual checking. Why a company would do this is beyond me, when they know the difficulties of instability of vitamin C formulations oxidising. If you didn’t trust them you would think they are deliberately trying to mislead. Do not buy tinted formulations of vitamin C.
The one I bought was placed in a glass bottle, with a pipette for me to withdraw the concentrate liquid. If you don’t use it carefully, the whole bottle will be oxidized and changed colour. I guess the one I bought was pure, as the colour was not brightly yellow. And it’s really expensive!
Nonetheless, if you would like to have intense whitening on your face, go for pure vitamin C, and remember to put sunblock in it when you are using during the day.
BTW, if you are as vain as me, please link Skin Revision and bookmark the site. It’s really informative.
