20 grams / 0.7 oz of pure vitamin C powder (L-Ascorbic acid) to be used in a freshly made skin serum as per our dermarolling instructions. Dissolves easily.

Due to the fineness of the powder it can also be mixed into creams but it does not dissolve into pure oils/fats, it needs the presence of some water to dissolve.

Note that almost all vitamin C available from pharmacies is the "buffered" non-acidic variety, neutralized with for example Sodium bicarbonate. Such buffered, non-acidic vit. C is not suitable for a microneedling skin serum.
Vitamin C is necessary for collagen synthesis. This vitamin C is made in Germany and purchased in a pharmacy, so it is excellent for use in salads as well.
Vitamin C skin creams or serums need to be freshly prepared to be effective. "Aesthetic Surgery of the Facial Mosaic" by Dimitrije E. Panfilov:
