Although Vitamin C is moretraditionally associated with keeping the body strong and helping stave off the common cold, did you know italso has many anti-aging benefits when applied topically to skin? This is especially important as we grow older as since our body’s natural antioxidant production abilities decrease.

TWO POPULAR FORMS OF TOPICAL VITAMIN C

L-ASCORBIC ACID

Vitamin C comes in many forms, with L-Ascorbic acid being the one backed by the most research as well as commonly used in skincare. This form of Vitamin C is not only known to protect skin against UV damage by fighting free radicals but also helps to increase collagen production, even out and brighten skin tone, as well as reduce hyperpigmentation (dark spots). One of the downsides is that this form of the vitamin is unstable and oxidizes rather quickly when exposed to air severely reducing the ingredient’s benefits to the skin. Another problem is L-Ascorbic acid can cause skin irritation and redness at the levels required for maximum anti-aging results.

MAGNESIUM ASCORBYL PHOSPHATE

Another popular form of Vitamin C, Magnesium Ascorbyl Phosphate, is much more stable, doesn’t oxidize as rapidly when exposed to air and is also gentler on the skin. It works effectively for certain aspects of anti-aging including collagen production, brightening and evening out skin tone, as well as reducing hyperpigmentation. The main downside is this form of Vitamin C does not have too much research supporting its UV protection abilities.

HOMEMADE VITAMIN C SERUMS: THINGS TO NOTE

  • Make small batches – the recipes below should last you up to 1 week. Be sure to check the serum’s pH levels, every few weeks to see how fresh it is, especially important when using L-ascorbic acid the less stable of the two forms of Vitamin C. If there is a yellowing/browning effect to the Vitamin Cserum, it means it has oxidized. Throw it out!
  • L-Ascorbic Acid should make up 10-20% of a formula in order to be effective, something that may take your skin some time to get used to. Anything below 10% won’thave real anti-aging benefits and above 20% will betoo harsh on the skin. Serums with this form of Vitamin C need to maintain a pH below 3.5 (ideallybetween2.5 and 3.5) in order to penetrate the skin’s barrier properly.
  • Magnesium Ascorbyl Phosphate is effective at levels as low as 10%, and though it’s considered pH independent we find that a pH of around 7 works well. This form of Vitamin Cis gentler since it’s less acidic and therefore is good for more sensitive skin types.

NOTES ABOUT VITAMIN C STRENGTH

L-ASCORBIC ACID

In order to achieve different strength serum levels, the below recipes contain progressively higher amounts of Vitamin C. Although the 5% formula may not have significant anti-aging benefits it’s recommended for beginner to start off with this one and then after 2 weeks switch to the 10% formula in order to let your skin slowly adjust and avoid irritation. Again after 2 weeks or more, level up to the 15% formula. After about 3-4 weeks or more if you feel like your skin is not seeing the results you’d like to consider trying the 20% formula.

MAGNESIUM ASCORBYL PHOSPHATE

Use the 10% recipe as per below (this is generally the maximum percentage of this form of Vitamin C recommended).

VITAMIN C SERUM RECIPES

5%SERUM

1/4 tsp of Vitamin C powder

4 tsp distilled water

3/4 tsp glycerin

10%SERUM

1/4 tsp Vitamin C powder

2 tsp distilled water

1/4 tsp glycerin

15% SERUM

3/8 tsp Vitamin C powder

2 tsp distilled water

1/8 tsp glycerin

20%SERUM

1/4 tsp Vitamin C powder

3/4 tsp distilled water

1/4 tsp glycerin

*Should you choose not to use glycerin, switch it out for the same amount of distilled water. Note this will create a much runnier texture.

INSTRUCTIONS

1. In a clean beaker dissolve the Vitamin C into the distilled water.

2. Add the glycerin into the mixture (skip this step if you’re not using this ingredient).

3. Pour into the amber dropper bottle and gently shake the serum until well mixed.

4. Use the pH kit to check the solution.

  • For serums using L-Ascorbic Acid, the pH should be between 2.5 -3.5 and 3.0-3.5 for sensitive skin.
  • For serums using Magnesium Ascorbyl Phosphate, the pH should fall between 6.0-7.0.

STORAGE

Store serum in anairtight, dark colored or opaque container in a cool dark place to prevent oxidization for up to 7 days (refrigeration can extend the shelf life). As we mentioned above, it’s wise tocheck the pH of the serum midway through the week and at the end of the 7 days to ensure it’s still within the acceptable range –if not, throw it out.

USAGE

  • Although it can be used twice daily, it’s better to start with just once until skin adjusts.
  • Apply serum and wait a few minutes before moisturizing.
  • Make sure to apply sunscreen on top of the serum if you’re wearing it in the day.

RESULTS

The results a Vitamin C Serum with an effective percentage (10-20%) can generally be seen after 4-6 weeks of usage.
