Vitamin C serum Active Ingredient : 1-1.2 grams Vitamin C (L-ascorbic acid) (approximately 1/4 teaspoon) (The active ingredient must be L-ascorbic acid, not vitamin C tablets, or calcium Ascorbate) This can also be purchased from Skin Actives.
Base Ingredients. 5 ml glycerine (1 teaspoon) 5ml water (1 teaspoon) You should be able to buy both the L-ascorbic acid and glycerine from your chemist store.
Process. 1. Dissolve 1gram of L-ascorbic acid in 5 ml of water (preferably distilled), in small glass container using a stirrer. Make sure it is fully dissolved before proceeding to next step.
2. Add 5 ml of glycerine and mix.
3. Put in a sealable jar, (not clear glass as this allows light in, and light degrades vitamin C.) Store in cool dry place.
Voila – your own fresh vitamin C serum. Apply to skin once per day to start with (preferably at night), and increase to twice daily if tolerated.
