Ascorbic acid is an organic acid with antioxidant properties. Its appearance is white to light yellow crystals or powder. It is water soluble. The L-enantiomer of ascorbic acid is commonly known as vitamin C.

Vitamin C is used in skin care products in the form of ascorbic acid. At a 10% concentration and low ph, ascorbic acid has been shown to stimulate collagen, decrease wrinkle depth and have lightening effects on pigmentation. It was thought that a minimum 10% concentration was required but newer information indicate that lower concentration (5%) may have benefit.

When Ascorbic acid is applied topically at levels ranging from 0.3-10%, the benefits are:
  • Potent antioxidant, particularly in regard to protecting skin cells from UV-induced damage
  • Delays tumor formation after (animal) skin is exposed to extensive UV damage
  • Has a low risk of skin sensitization at concentrations up to 10% in the form of ascorbic acid
  • Reduces transepidermal water loss, thus strengthening skin's barrier response
  • Promotes collagen production and has the potential to thicken the dermis
  • Reduces inflammation
  • Ascorbic acid at levels of 5% and above has a positive effect on hyperpigmentation (though the results are not as impressive as hydroquinone, suggesting a combination of the two would be optimal)
  • Improves the appearance of sun-damaged skin by strengthening skin's repair mechanisms
  • Enhances the effectiveness of dermatologist-performed procedures such as peels and microdermabrasion

The kit includes:

  • 2 packs 1g L-Ascorbic Acid (USP)
  • 2 bottles 5ml vegetable glycerine
This recipe makes a serum with approximately a 10% concentration of vitamin C. There will be 2 portions, 1 for each week, to maintain freshness since L-Ascorbic Acid is unstable, prone to oxidation. Do keep the prepared serum in the fridge for longer lifespan.

Take care- these are active ingredients At this concentration it will have a relatively low ph, and in some people this will be too irritating for the skin. If this is the case, try making a half or even quarter concentration to start with (ie using less of L-Ascorbic Acid). Use this for a week or two until you know you skin is tolerating this, and then slowly increase to a higher concentration. If after you apply it, you find your skin is tingling excessively, wash off immediately.

Process:

  1. Dissolve 1 gram 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/bottle (you may use the containers we provide, do not use clear glass as this allows light in, and light degrades vitamin C.)
  4. Store in cool dry place.

If you have access of L-Ascorbic Acid vs Glycerin, fret not. Simply dissolve the L-Ascorbic Acid with water and mix into your favourite face cream. We advise a storage of 3 days supply and preferably in the fridge.
