Why are essential oils with Vitamin C not mentioned? They are much more stable, there are many which are very unlikely to cause negative reactions, and Do cross the skin barrier. Which essential oils are the best for adding vitamin C to the skin? How do they compare to the powders you are mentioning in reguards to aiding the skin?
PLEASE research before you reply, because I can see that before I mentioned this it has not been looked into. However, I am curious what you will come up with AFTER research.
Thank you in advance.
