DIY Vitamin C (I have been using this for FIVE YEARS and have so much left. I make a fresh batch whenever I need it.
INGREDIENTS
Vitamin C https://amzn.to/2Xu6hJ7
Hyaluronic Acid https://amzn.to/2U98dEZ
Glycerin https://amzn.to/36WoaDP
Funnel https://amzn.to/2zO3wcV
Amber Glass Bottles https://amzn.to/3gSILxp (I use the other bottles for oils, or rebottling larger clumsy bottles of things)
If you put the glycerin in first, it may mix either. I find it is runny unless I use the hyaluronic acid (which I love!). I hope that you enjoy.

DIY Vitamin C
1/8 tsp Ascorbic acid powder
1 7/8 tsp water
1/2 tsp Glycerin
10% solution
1/4 tsp Ascorbic acid powder
1 3/4 tsp water
1/2 tsp Glycerin
15% solution
3/8 tsp Ascorbic acid powder
1 5/8 tsp water
1/2 tsp Glycerin
20% solution
1/2 tsp Ascorbic acid powder
1 1/2 tsp water
1/2 tsp Glycerin
Directions
1) Add Vitamin C, Water. Glycerin to a CLEAN and DRY 1 oz. Amber Glass Treatment Bottle.
2) SHAKE vigorously. Set it aside while you go do something else. Come back later and shake it some more. Do this until there is no powder left. If there are a few crystals left at the bottom, this is okay. They will dissolve. If there are A LOT of crystals left and you’ve been shaking a while, you may not have added enough liquid.
NOTE: Glycerin is optional. BUT if you left out glycerin, you MUST add water for that portion of the recipe or the concentration will be too high and the crystals may not dissolve properly.
Hyaluronic Acid Serum
You can make a large batch of this recipe and store it in the refrigerator. Small amounts of this BASE can then be taken from the batch and powders can be added directly to that smaller portion. This method (See Combo recipe below) is a faster way to make your weekly serums.1/4 tsp Glycerin
1/4 tsp Hyaluronic Acid Powder
1 oz distilled water
This mixture can last in the fridge for up to a month so feel free to double as desired.
How to use this serum base:
-Use as a serum in the morning and evening (just as it is) before applying facial moisturizer/
-Add serum base to shampoo and/or conditioner for added hydration in your hair!
-Use as a BASE SERUM RECIPE and add vitamins, peptides, etc., to create your own personalized serum.
-Mix a SMALL amount of the BASE SERUM RECIPE with some hydrosol and add to Moisturizer Cream
Vitamin
C and Hyaluronic Acid Serum Combo
There are two methods to making this serum.Method 1: put it all together from scratch.
Method 2 use THE BASE SERUM RECIPE above
Method 1 Combination Serum with 20% Vitamin C.
Makes 1 oz. of serum. This may be too much for most people to use up within 5-14 days. If you prefer this method and don’t want to throw a bunch away at the end of the week, put it ALL OVER you body to use it up faster or cut in half or use Method 2 below.
1/4 tsp Hyaluronic Acid Powder
1 1/2 tsp Vitamin C Powder (L-Ascorbic Acid)
1/4 tsp Glycerin
1 1/2 tsp Distilled water
Directions:
In a tinted glass bottle, add powders, then glycerin then water. Shake well. Shake well again 4 hours later.
This mixture should be discarded as soon as it beings to oxidize (turn yellow). Go by the color but it is usually around 2 weeks for me (storing in a dark cool location)
Method 2 Combination Serum with 5%-20% Vitamin C
Prepare the recipe for Hyaluronic Acid Serum base (recipe above). The prepared Hyaluronic Acid Serum will be the total liquid part of your recipe. Take small amounts of this each week and put the vitamin C powder into it to prepare the combination serum. You can make as much Hyaluronic Acid Serum as you will use for one month and keep it stored in the refrigerator.
Choose the recipe below for the concentration of Vitamin C you wish to prepare.
Combination Serum with 5% Vitamin C
1/8 tsp Ascorbic acid powder
2 3/8 tsp Hyaluronic Acid Stock Solution
Combination Serum with 10% Vitamin C
1/4 tsp Ascorbic acid powder
2 1/4 tsp Hyaluronic Acid Stock Solution
Combination Serum with 15% Vitamin C
3/8 tsp Ascorbic acid powder
2 1/8 tsp Hyaluronic Acid Stock Solution
Combination Serum with 20% Vitamin C
1/2 tsp Ascorbic acid powder
2 tsp Hyaluronic Acid Stock Solution
Directions:
1) Place the Hyaluronic Acid Stock Solution into a 1 oz. Amber Bottle
2.) Add the Vitamin C powder.
3.) Using the stem of your bottle stir the powder into the gel.
4.) Cap the bottle and SHAKE vigorously to dissolve the powder.
Sometimes it takes a few minutes longer for the Vitamin C powder to dissolve into the gel vs. in plain water, because the gel is a little thicker. You can let this solution sit and shake it once in a while until it’s dissolved. -Product can be used immediately on the face or anywhere on the body where benefits are desired. This mixture should be discarded after 5-14 days or when it begins to oxidize (turn yellow).
Oh, that is a great idea! I am going to give it a try as well. I might try putting a few drops into a dish or plate and mixing in the powder first just to make sure it works before adding it to the whole bottle.
ReplyDeleteI want to make the Method 2 Combination Serum with 20% Vitamin C, and I just want to verify that you mean teaspoons (vs tablespoons, so many recipes accidentally abbreviate them wrong!) I have 1 oz airless pump bottles, which really seem to prolong the life of my oxygen-sensitive oils, so I thought I'd try doubling your recipe and seeing how long the result lasts before changing color.
ReplyDeleteWhat other vitamin c powder can I use
ReplyDeleteThis is a great post! I've been making my own combo vit c and hyaluronic acid serum for about 2 years. The serum I use is about the same recipe as your 20% serum. I use it on my face, neck, chest and arms. Sometime I also make a second serum without glycerin for my hair. I often make a large batch and freeze half to use later.
ReplyDeleteThanks Elle for all the great info and ideas you share!
Isn't it fun being a mad chemist :-)
ReplyDeleteElle
ReplyDeleteI’d
Ike to try the hyaluronic acid plus the vitamin C together. When you say “stock” do you mean the large amount of of hyaluronic recipe above?
Yes! I hope that you love it.
DeleteI came across your blog by accident. Great info. Where would I buy hyaluronic acid? Thank you so much for posting all your info.
ReplyDeleteMaureen
I have links near the top of the blog post to all the products I purchase from Amazon.
DeleteHow long do uou leave these on?
ReplyDeleteAll day or overnight. It is part of my skincare routine.
DeleteThank you!!!
ReplyDeleteCan I use normal bottle water or does it have to be distilled water
ReplyDeleteYes, you could use bottled water. I wouldn't use tap water due to the impurities that could grow and shorten the life of the vitamin c
DeleteThank you for reply
DeleteThat is a great question, and I wish someone who knows would answer this one. If it helps, I did make a plain water/hyaluronic mix with bottled water, which I keep in the fridge and have been using for weeks. This could still could be so "wrong" for all I know, but my skin hasn't fallen off! ;-)
ReplyDeleteI used 1/4 tsp Ascorbic Acid powder, 1/4 tsp hyaluronic acid powder, 1/4 tsp glycerin and up to 2 tsp water but it did not dissolve well and was so thick I would even shake loose. I added more and more water but it’s stll horribly thick. What did I do wrong?
ReplyDeleteI have no idea as if anything, it usually isn't super thick until after you have shaken it a few times and it sets up overnight. Did you use the same products as I have linked above or did you use different products?
ReplyDeleteYes. I ordered all of them from Amazon from the links you provided. I watched your video a few times and did it as instructed. After I shook it up initially, I came back a little later to see that the powder was not completely dissolved. I could see chunks of it in the gel. But it was also already so thick that I added more water and shook it up again. I came back later and again it was so thick it would t shake up. I added MORE water and some more glycerin and it didn’t help. It’s super thick and clumpy. When I try to get it out of the bottle, it is all stuck together. I just can’t figure out what I did wrong. This was my first attempt so I’m trying to make sure I don’t do that again.
ReplyDeleteI have no idea - maybe it is your elevation? If I was you, I would mix the powder and water and shake that up and then shake it again a few hours later. Since both the hyaluronic and glycerin thicken, I would add the hyaluronic and shake it and leave it a bit and then add the glycerin if needed. As I said, most people have the opposite problem but hopefully that helps you!
ReplyDeleteGreat thank you for the reply
ReplyDeleteAssuming an error in Vitamin C measure on Hyaluronic Acid Serum Combo. 20% vitamin C previously 1/2 tsp, but combo indicates 1 1/2.
ReplyDeleteI am not clear what you are referring to with the 20% solution you make it as per the Vit C direction and then add in the HA.
DeleteThe same thing happened to me about the thickness. should I fill the 1 oz bottle with water, or is it really just 1 1/2 tsp of water?
ReplyDeleteThank you girl!! It is perfect!! ❤️
ReplyDeleteAwww, thank you! ♥
DeleteIt is because of the hyaluronic acid, hyaluronic acid can hold the water very strong, try adding up from 0.1g, increase it until you got the texture you want. Hope this could help.
ReplyDeleteWhat can I add to this to make it last longer? I would like to sell in the future
ReplyDeleteso if I follow the recipe for the 20% vitamin c serum it comes out to 2 1/2 tsp of total serum?
ReplyDeleteExactly, Vitamin C is the most effective and essential nutrients for our body, Vitamin C is most important for everyone,
ReplyDeleteThe hyaluronic acid should sit in the water/glycerin mixture overnight in the fridge, without shaking!! When you check it in the morning it will be perfect. Add the appropriate amount of ascorbic acid and shake. Leave for 5 minutes or so, shake again, and it should be ready.
ReplyDeleteI have been making it for years and years without doing it the night before and it always comes out perfectly.
ReplyDeletehi, if I want to add preservative so it has a longer shelf life, what do you recommend?
