    Hi, I was wondering why the directions say to make in small batches and use in 3-5 days, is it perishable? Also is it ok to use daily?

    • February 20, 2014 / 4:43 pm

      Hi Laurianne, yes, when you mix L.Ascorbic acid with a liquid it goes bad within 3-5 days. It is ok to use daily!

    Hi Jenni,
    I just made your Vit. C serum and tried it tonight. I followed the instructions, but couldn’t get the vitamin C powder to dissolve completely in the solution. When applied it felt granular still. It also has a slightly uncomfortable burning sensation. Is this normal?

    • February 24, 2014 / 3:46 pm

      Stephanie-unfortunately it is normal. I have found a brand of L.Ascorbic acid that is water soluble though-I haven’t tried it but I will as soon as mine runs out. The burning is normal but if it’s too much you should reduce the amount of l.ascorbic acid next time you make it. A little burn is fine, but not too much. Since it’s an acid there’s no way around a little burning. Thanks!!

        Hi Jenni, Just seen this post and I know it is 4 years old, but I have found a company called Deciem and they do a range of beauty products called The Ordinary and they have recently launched a Vitamin C powder which is soluble in oil and water and it is brilliant. I just add it to my facial oil and apply to my face.. They are a Canadian based company but they have stockists in a few countries including the U.K. Hope this helps.

          Nuria-Thanks for this info! I have heard there are better options now for Vitamin C but I hadn’t looked into it!

    Hi Jenni!

    I love your products! I was wondering….I’ve seen others that say if you store this serum in the fridge it lasts a lot longer. Is that true? I love using this but making it every 3 to 5 days is a bit much. Thanks!!


    • February 26, 2014 / 7:00 pm

      Hi Gayle! I’m afraid there is no way around it-Vitamin C is so unstable, but I think you’ll find the results make it worth it. It really is so easy to mix up too. I don’t believe the fridge will help. Thanks!

      • Gayle
        February 27, 2014 / 4:47 pm

        Ok, thanks so much! It’s hard to know what’s true when there are so many “experts” saying different things. But I trust that you know!

    This sounds amazing, if it works on sun damage, I’ll be using it on my chest and hands as well as my face! You mentioned the water soluble L.Ascorbic acid, have you used it yet? What do you think of using Rosehip oil and Frankincense for an added boost for repairing sun damage?

    • February 26, 2014 / 5:11 pm

      Jennifer-I love the idea of Rosehip and Frankincense-that would be AWESOME to add to your l.ascorbic acid! No, I haven’t tried the water soluble yet-as soon as I’m out of my current vitamin C, I will.

    • Nicole
      March 28, 2014 / 10:30 am

      I have a lot of sun damage too! How would you mix it up with rosehip oil and frankincense??

      • March 28, 2014 / 12:15 pm

        Nicole-I would replace glycerin with rosehip then add about 3 drops of frankincense!

  5. Mel
    March 12, 2014 / 8:14 pm

    Hi Jenni, can I know if I can use the L-ascorbic acid to the Vitamin C serum? and also the same glycerine for both recipe? or does it have to be different? and after apply the serum and the mask on back of arms, do I need to moisturise further? Thanks!

    • March 12, 2014 / 9:59 pm

      Mel-I’m not sure I understand-The serum has l. ascorbic acid. You can mix just about anything you want with the l.ascorbic acid-aloe, almond oil, water etc. Glycerin was my suggestion. If your skin feels dry and tight after applying the serum/mask you can use a moisturizer but otherwise, you don’t need to. Thanks!

      • Mel
        March 13, 2014 / 2:05 am

        i’m so sorry! I thought that I was in the VIT C MASK page. it seem that the ingredients are quite similar and am wondering if I can use the same glycerine for both the serum and the mask. anyway, I have ordered the ingredients for the serum! excited! ^^

      • Mel
        March 19, 2014 / 4:14 am

        Jenni, can we apply the serum to the eye as well?

        • March 19, 2014 / 7:45 am

          Mel, yes, but be so careful, the serum will burn if it gets in the eyes. Remember that eye creams and serums do travel so apply them at least 1/2 an inch under the eye. Thanks!

          • mel
            March 20, 2014 / 9:57 am

            Thanks again Jenni. I hv tried out tonite. Vit c dissolved,added half of glycerine ratio to water (0.5 : 1). the serum feels watery bt after application its really sticky even when i put very little glycerine. Is this normal?

          • March 20, 2014 / 6:50 pm

            Mel-Yes, it’s not the most luxurious serum. You can always try omitting the glycerin and using a carrier oil instead.

  6. Nicole
    March 28, 2014 / 10:28 am

    If we aloe instead of glycerin, does water need to be mixed with it as well? Would I would the same ratio? Thanks!

    • March 28, 2014 / 12:15 pm

      Nicole, if you replace anything just keep it the same amount as the glycerin would have been. No water necessary!

    Hi jenni!
    I would like to congratulate you for your blogg and your knowledge.
    I would like to know the difference between the vitamine C mask and the vitamine C serum.
    Do they have the same effect?
    If I use the serum, how often should I apply it on my face? Should I left it during the all night?
    I have a mixed skin, what type of tonic do you recommend me?
    Thank you for your help and professionalism.
    Best regards,

    • April 20, 2014 / 4:16 pm

      Hi Tamara! Thank you so much! I created the Vitamin C mask for people that didn’t want to commit to using the Vitamin C serum daily. The results are the same, they will just come quicker if you use a serum daily.
      If you do the serum you apply it at night after cleansing your skin-you do not remove it. Hope this helps!

    Hey, J! Just found my way to you and this serum a week or so ago. Very excited to get into it and the rest you have to share! 2 questions: I saw you mentioned coconut oil could be subbed for glycerin. How do you get around the coconut oil being solid? I’ve been trying to mix up my recipe but the coconut oil won’t dissolve. AND with this recipe, how much should one apply? A whole dropper full? Thanks! Jennifer

    • June 5, 2014 / 4:33 pm

      Jennifer-It won’t stay solid, you’ll have to scoop it out unless you use fractionated coconut oil-it stays liquid. I would apply enough to cover you face lightly. Don’t use too much since it can be sticky and also too strong. Hope this helps!!

      • Jennifer Fisher
        June 5, 2014 / 7:12 pm

        Thanks for responding…. I’m a little confused though. I use organic virgin coconut oil – for cooking and many other things….. It’s always solid in the jar unless it’s super hot. Are you saying there’s a coconut oil I could get that stays liquid? Thanks!

        • June 7, 2014 / 11:11 am

          Jennifer-Yes! Fractionated coconut oil has the fats removed so it stays liquid always. Spark Naturals has some that I like-

          • Jennifer Fisher
            June 9, 2014 / 3:49 pm

            Awesome, thanks!! I’ll check it out!

          • Jennifer Fisher
            June 17, 2014 / 12:40 am

            One last question! 🙂 Can I use the Macadamia nut oil in your anti-aging serum recipe as the carrier oil for the Vitamin C serum? It smells and feels so good. Thanks!

          • Jennifer Fisher
            June 18, 2014 / 1:12 am

            Awesome! That anti-aging serum smells so yummy, I wanna eat my face off! 😉

          • Jennifer Fisher
            June 27, 2014 / 12:30 am

            J…. Me again, with (hopefully) one last Vit C serum question! I used the macadamia nut oil but the serum was much drier. The Vit C crystals were just kind of sitting there on my skin. I used the macadamia nut oil alone. Should I be mixing it with the glycerin or something else? Thank you…AGAIN! J

    Hi I have organic camu camu powder. Would I be able to sub this for the L-ascorbic acid?

    • November 26, 2014 / 2:51 pm

      Grace, I have heard Camu Camu is an acceptable substitute but I’ve never tried it!

  10. Lisa A
    January 21, 2015 / 8:44 pm

    I bought the Health Force brand of vitamin C today but noticed that it doesn’t list L-absorbic acid as an ingredient. I’ve read on other sites that is the important ingredient for this serum to work. Should I buy a different brand or will this work? Also, can I used rose water instead of distiller water? Thanks so much and I love your blog!

    • January 23, 2015 / 12:46 pm

      Lisa-I would purchase only pure L.Ascorbic acid. It is not a synthetic gmo vitamin C like ascorbic acid and comes in a powder form. I have linked what I specifically used on the recipe. I’m not sure if what you have will work since I’ve never used it but I wouldn’t take a chance. This isn’t the most enjoyable serum so if you are using it, you want to make sure it’s effective! Thanks!

      • Lisa A
        January 23, 2015 / 2:39 pm

        Hi Jenni,
        Thanks for the reply! The Health Force brand of vitamin C that I referenced in my last comment was the one that you linked to at Should I return that bottle and buy L.Ascorbic Acid instead? If so, what brand would you recommend? Thanks again 🙂

        • January 28, 2015 / 10:38 am

          Lisa-Primally Inspired linked that product and honestly I trust her because she is so aware of GMOs and staying natural. I’m sorry-I didn’t realize she had linked something other then the L.Ascorbic acid that I had linked originally! HERE is the brand I use.

  11. February 2, 2015 / 12:24 am

    hii.. im a newbie in this DIY thing.. i’ve tried different kind mixing (all easy one though) for vit C (ferulic+sea kelp,vit e) and now i want to use this ingredient but i dont know how many i should use.. pls help
    -vit c powder
    -vit e
    -aloe vera
    -almond oil
    -(should i use?) distilled water

    thanks so much

    • February 3, 2015 / 8:33 pm

      KeeKee-I’m not sure I would make this recipe this complicated. The thing is, Vitamin C is very unstable so you only want to make enough to last you about 5 applications. Otherwise it’s pointless. If you need some nourishment along with your vitamin C (which you will bc vitamin C is an acid and can be drying), I would make a serum to use after you have removed the Vitamin C serum. Something like almond oil, vitamin E and lavender oil. Your skin would appreciate that after the vitamin C serum! Does this make sense? Also, be careful not to mix waters and oils. You will have bacteria issues, big time. Aloe is water based so I wouldn’t mix it with oils either.

    I love this! I have been using this for a week and can already see a difference in my skin.

  13. Kris
    February 15, 2015 / 2:29 pm

    Could this be mixed at each application rather than every few days? Would it work in a hyalauronic acid carrier? I currently use philosophy vitamin c powder and add it to my serum in my palm each morning. Easier for me than mixing batches every few days.

    • February 17, 2015 / 9:30 pm

      Kris, Yes you could mix everyday-In fact, this is the best way to do it. This way you make sure it is pure and potent!

      • Rose
        May 15, 2015 / 9:23 am

        If you mix it daily as Kris does, how much Vitamin C powder and carrier oil would I use in the palm on my hand?

        • May 20, 2015 / 7:48 am

          Rose, That all depends on how it feels on your skin. You will have to experiment to see what works. You don’t want your serum to sting. Maybe a little is ok but not much. I would just play with your proportions each day.

  14. Gina Martinez
    June 16, 2015 / 11:44 pm

    Hi jenni. How long should the vitamin c serum be left on? Tia!

    • June 23, 2015 / 7:30 am

      Gina, You should be using a small amount and leave it on. If it is uncomfortable then you should reduce the l.ascorbic acid. If it’s sticky then I would leave it on as long as you can, then remove when you need to. Hope this helps!

  15. August 17, 2015 / 6:36 pm

    I have made the Vitamin C Serum with ascorbic acid and Vitamin C powder – followed the recipe very carefully but
    it is granulated – is it still efficient – the vitamin C I used is CAMU POWDER organic 100% – but I keep grinding it and it is still granulated – should I still use it – Looking forward to hearing from you – Thank you

    • August 18, 2015 / 7:20 am

      Jacqueline-Unfortunately with this serum it will be a bit granulated. It’s one of the most effective diys but not the most luxurious and comfortable! It is still effective-no worries. That’s why I prefer doing my vitamin C in mask form. Go HERE for that!

  16. Nicole D
    September 13, 2015 / 9:17 pm

    Hello Jenni! I love the idea of a homemade C serum, especially considering how expensive and unstable pre-mades are. However you mention using pH strips to make sure the serum sits right around a 3.5- I have checked mine and it’s about a 2! Do you know of any way to adjust the pH up to 3.5?
    Thank you!

    • September 17, 2015 / 8:51 am

      Nicole-I just read that you can go as low as 2.5. 2 is a bit low. I’m not good with pH but I think you could add more of your liquid-dilute the vitamin C a bit more and your pH should rise. Good luck!

      • Nicole D
        September 17, 2015 / 9:10 pm

        Jenni- Thank you for this! I have also since discovered that a tiny amount of baking soda is an effective pH raiser.
        Best regards!

        • Lisa
          September 18, 2015 / 3:55 am

          I recently made a small batch. Can this be used every day? Also if I don’t have ph strips and it happens to not be in the range you suggest, is it just not effective at all? Or will I get some benefits?

          • September 28, 2015 / 9:32 am

            Hi Lisa! Yes, you can use it daily. The thing with pH is that if it’s too low it could burn and be too strong. If it’s too high it won’t be effective. You can tell what proportion you need by how your skin feels. Tingly is good-burning is bad and nothing could be ineffective. Hope this helps!

  17. CherryS
    September 21, 2015 / 10:14 am

    If you place the vitamin C serum in a one ounce roller ball container, will this help it last longer? The theory is the roller ball prevents air from oxidizing the Vitamin C.

    • September 21, 2015 / 11:09 am

      Cherry-I don’t know, I haven’t heard of that but I like that idea-it does make sense. I guess there is really no way to tell how long it adds to the shelf life though.

  18. Yvonne
    January 11, 2016 / 5:24 pm

    I’m 63 and now face the horror of a crepey neck and jowls (thanks Dad). Thankfully I don’t have crows-feet or other aging signs to deal with. I’ve purchases organic rosehip oil and vitamin c serum and wanted to know if I can mix the two somehow, and use nightly. What would be the proper ratio? Could I use coconut oil with these as well?
    Thanks for any advice!

    • January 14, 2016 / 1:30 pm

      Yvonne-Hi! Well, vitamin C is water soluble so it has to be dissolved in a water based substance such as glycerin, aloe vera gel, witch hazel or distilled water. I’m afraid in order to use both Vitamin C and rosehip, you would have to do to different products. I just posted a recipe with rosehip-it’s a super easy serum that you could make and apply after you vitamin C serum soaks in. Find that serum HERE. Hope this helps!

  19. Tin
    February 10, 2016 / 2:17 pm

    Hi! The Vitamin C on the link says that it contains 270mg of Vitamin C per 7.5 grams of the powder. Basically, it contains 3,6% of vitamin C per 100% of powder. Is this correct? What if I use some other form of Vitamin C? How much Vitamin C in mg or grams should I use per 1 tsp water? Thanks 🙂

    • February 28, 2016 / 10:26 pm

      Tin-This recipe, since it is not on my blog does not contain my links to the products. I have not used this type of vitamin C for this product. I use THIS Vitamin C powder that I believe is more pure. Sorry for the confusions!

  20. Rosa
    February 11, 2016 / 2:15 pm

    If I get rid of the glycerin and distilled water and replaced them with aloe vera gel, would it still work? And would the shelf life for it be any different?

    • February 14, 2016 / 4:05 pm

      Rosa-Yes it would work! Aloe is water based so the Vitamin C should dissolve. It doesn’t effect the shelf life-it’s still very short.

      • Rosa
        February 16, 2016 / 10:49 pm

        Could a preservative like Natapres keep it from going bad too quickly?

        • February 21, 2016 / 1:36 pm

          Rosa-Unfortunately it’s all about the L.Ascorbic acid becoming ineffective not about bacteria or mold.

  21. Nanette
    April 10, 2016 / 1:14 pm

    On a whim today I bought a bottle of liquid V C (500mg). Then went to the internet looking for a way to use it on skin and ended up here. Any suggestions for using the liquid in lieu of the L ascorbic powder?

    • Jenni
      April 10, 2016 / 1:19 pm

      Nanette-I have never worked with a liquid form of vitamin C-I’m intrigued! Is it for internal use or topical?

  22. Mary M
    April 16, 2016 / 5:17 pm

    Hi Jenni,

    I have mixed Acerola Cherry Extract powder (can this be used for the Vitamin C?), glycerin and distilled water using the amounts you stated. I must say that it smells awful and is extremely sticky! When I first applied it, I had to wipe the excess off my hands as it was so sticky. Is this, (and the smell) normal?

    Many thanks
    Mary M

    • Jenni
      April 19, 2016 / 9:38 am

      Mary-Sticky is normal with glycerin. You could cut the glycerin amount in 1/2 and use aloe or more water in it’s place. The smell is not normal with L.Ascorbic Acid so it might be your extract. Does it fade after a time? You might check out the L. Ascorbic acid instead. Good luck!

  23. Lisa
    June 27, 2016 / 9:17 pm

    Hi Jenni-

    I got my L. Ascorbic Acid from Lotion Crafter. It mixes great but do you think it’s an acceptable product?


    • Jenni
      June 28, 2016 / 2:51 pm

      Lisa-I think so. I like that company-they aren’t the most natural with everything but I’m not so sure we can get super natural L. Ascorbic Acid.

  24. Lisa

    March 18, 2017 / 9:35 pm

    Hello Jenni!
    I’m going to attempt your recipe using Camu Camu powder because I already have it. But I’d like to know in case I do need to purchase the vitamin C powder, if vitamin C (L. Ascorbic Acid) is so unstable, how can it be sold in quantities? If only 1 tsp is needed for your recipe and only good for up to 5 days, wouldn’t the remainder of the powder have lost potency as well?

    • Jenni
      March 25, 2017 / 4:41 pm

      Von Marie-It only starts to go bad once it’s mixed with a liquid. The powder itself is stable. I have heard Camu Camu powder is great to use!

    Hi Jenni,
    I’m trying to make your vitamin c serum and I am using everything you suggested but the powder. I purchased this vitamin c powder before I found your blog. I cannot get it to dissolve enough to use it. I read a comment some body else left that was having the same problem and you said you were going to try another kind of powder your self. I was wondering if you found a vitamin c powder that works better as my funds are very limited?

    • Jenni
      October 10, 2017 / 5:14 pm

      Debbie-I have not found another Vitamin C powder that dissolves better. It seem to me that this is a problem with all vitamin C powders. I have ended up adding a pinch to my face cream and that seems to help. Plus it’s easy and isn’t sticky. I wrote about it HERE.

  28. February 12, 2018 / 6:08 am

    I bought BFC L-ASCORBIC ACID LR (Vitamin C) – 25gm CAS No. 50-81-7. (C6H8O6) . by Amazon.
