3 1/2 teaspoon distilled water (at room temperature)
1/2 teaspoon L-ascorbic acid powder (vitamin C)
1 1/2 teaspoon vegetable glycerin
1 dark glass bottle
Clean the bottle with rubbing alcohol or boil it in hot water. Let the bottle to cool and dry. Add the L-ascorbic acid to the bottle. Add the distilled water. Shake the bottle o use a something to stir it up, until all the L-asorbic acid is dissolved. Add the vegetable glycerin. Put on the cap and shake well, until everything is blended. Use up and make a new batch every 5 to 7 days. L-ascorbic acid is highly unstable, so you have to make a new batch frequently.
