Vitamin C Serum

Hi Everyone!  This week I’ve been a guest blogger for an awesome blog, Primally Inspired!  I’ve been busy working to perfect an old beauty secret that I’ve used for years!  It’s a Vitamin C serum!  Vitamin C is so amazing for your skin-it promotes collagen production, fades sun and age spots and is a powerful antioxidant!  This is another super simple recipe with easy to find ingredients that are going to give your skin that boost it’s looking for!

Head over to Primally Inspired to check out my Vitamin C serum post!


  1. 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?

  2. 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?

    • 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!

    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!!


    • 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!

      • 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?

  5. 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!

    • 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!

      • 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! ^^

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

        • 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!

          • 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?

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

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

  7. 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,

    • 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!

  8. Jennifer Fisher says:

    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

    • 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 says:

        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!

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

  10. 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!

    • 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!

      • 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 🙂

        • 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. 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

    • 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.

  12. Anna Wallace says:

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

  13. 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.

  14. Gina Martinez says:

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

    • 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. 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

    • 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. 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!

    • 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!

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

        • 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?

          • 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. 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.

  18. 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!

    • 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. 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 🙂

  20. 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?

  21. 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?

  22. 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

    • 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. Hi Jenni-

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


    • 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. Jenni-
    Great, thanks for responding 🙂 I truly value your opinion!
