Vitamin C Serum

I came across this serum many years ago via Facebook because of a fan page I liked and it is a Vitamin C Serum recipe (please feel free to see original recipe) which I used for several months. I originally wrote this on my blogger account and received over 3300 views over the years, but that’s not really of importance since I’m sharing it here and that blog no longer exists; just gives you an idea that people liked this post. Vitamin C serum does cost quite a bit of money if buying from a company that offers it, so making it is a good option.  The ingredients may even cost less rather than buying this type of serum from a company that makes it especially over time and if you already have some of these tools and ingredients on hand, then it’s even more cost efficient.

I have tweaked the ingredients and my recipe is similar except I added water from the beginning, then after a few weeks started adding Castor Oil. Eventually I added Vitamin E oil and starting using hot water instead of just cool water.  With my research in the “what you need will need & why” section, I cover why each ingredient is used in this serum.  It’s important to give you the best information I know of each ingredient and why to use it in this serum, so you can understand the benefits.

Homemade Vitamin C Serum

What you will need & why:

A dark colored (amber) glass bottle and can use an empty serum bottle, just make sure it is clean.  Need to use a dark colored bottle & keep serum in a cool, dry, and dark place because it will prevent the breakdown of the components & properties of the mixture and of each ingredient.

Vitamin C powder (L ascorbic powder) can find this at your local health food store that carries products in bulk or you can a find place to purchase online.  Vitamin C helps with protecting skin cell and the skin’s support structure from UV-related damage; improve the appearance of sun-damaged skin; strengthen the skin’s barrier response; reduce inflammation; promote collagen production; enhance effectiveness of peels and microdermabrasion; lessen hyper pigmentation (at levels of 3% or greater); and boost the efficacy of sunscreen actives. It has anti-inflammatory, antioxidant, and anti-aging properties.

100% pure Vegetable Glycerine which is a great base for serums and makes your skin soft and give it a dewy glow, so it gives a healthy appearance to the face.  It is a great moisturizer and may alleviate acne problems by balancing the pH of your skin. It is hypoallergenic & has anti-bacterial and anti-inflammatory properties.  It aids in preventing breakouts and keeping pores clear. It helps with skin conditions such as psoriasis, eczema, and any dry patches one may have.

Purified, distilled, or filtered water because it will help if you have problems with getting the Vitamin C crystals to dissolve.  The water should completely help dissolve any of the grit from the crystals especially if the water is hot (boiling). Water helps combine all the ingredients together.  Our skin needs water just as much as our body needs it as our bodies are 70% made of water.  Water hydrates our body from the inside out.  We should know all the benefits of consuming water, but it’s even important for our skin. Water is the world’s best beauty elixir and helps with any kind of beauty product. Water naturally plumps skin, fills in fine lines and wrinkles, and boosts lackluster complexion.

Castor Oil helps with keeping your skin youthful and unlined (meaning helps with wrinkles) and it is claimed to be better than any store bought anti-aging crème. It is rich in ricinoleic acid, which possesses anti-inflammatory, anti-bacterial, and anti-fungal properties, so it’s good to use on ringworm, skin tags & moles (if used in conjunction with baking soda to make a paste), diminish stretch marks, calluses, & that’s just to name a few skin conditions it helps. It is extremely thick and sticky, so if you don’t like it in the serum, don’t use and just add 1/2 tsp more Vegetable Glycerine. I added Castor Oil because of the benefits to the skin and I felt it was too watery and needed a thicker consistency. With only using the serum at night, I don’t mind the slight sticky consistency. When I used this, I applied this serum before bed and dabbed straight Castor Oil around the eyes.

Vitamin E Oil has anti aging, skin healing properties (helps with dark spots and acne scars), and hydrates the skin. Adding this oil to the serum gives the ability to be applied to the skin smoothly. This helps the grainy consistency of the Vitamin C crystals to become less gritty.


Notes: Be sure to use only cold-pressed (or cold-drawn) Castor Oil that is hexane-free. Any other kind could clog your pores. Another good reason to use Cold-Pressed Castor Oil instead of Refined Castor Oil is that cold-pressed oils retain much more of their valuable nutrients.

Make sure to splash water on your face in the morning in order to remove serum. This is a winning combination of ingredients that will help improve one’s face/skin more than you can possibly imagine because of the properties of each ingredient.

Directions:   Please read entirety of directions before making the serum.

  1. 1 tsp of Vitamin C powder and crush it with a mortar and pestle.  I have found this is the best way to crush the Vitamin C powder.  Doing this helps break down the crystals. so they will become smooth and not be grainy.
  2. Transfer the vitamin C powder in a small bowl (even using a clear ramkin is a good choice, it is what I use), and mix with 1/2 tsp of Vegetable Glycerine, 1/2 tsp Castor Oil, & ½ tsp Vitamin E oil. If you don’t like Castor Oil in the serum, then don’t use and just add 1/2 tsp more Vegetable Glycerine. I do suggest making this recipe as is the first time, then if need to make modifications over time. I use a fork (from the silverware) to blend the ingredients; don’t use a plastic fork. 1 tsp purified, distilled, or filtered hot (boiling) water will help if you experience having a grit to it (I used this regardless because I think it helps with the consistency with the serum).
  3. Once mixed together, add ½ tsp more hot water.
  4. Carefully pour serum into glass serum bottle.  Can use a small funnel if you have one to help get all of the serum into the bottle & make sure all of it gets in the bottle. Once in the bottle, shake it really good.  Be sure to shake before each use in order to help mix the ingredients.  
  5. If using straight Castor Oil around eyes put that on first and then lightly use a drop of the serum on eyelids.  The Castor Oil will feel heavy around eyes, but a drop of it is all you need. Massage and pat with the pad of your fingers both the Castor Oil and the serum on eyes.   Do not use serum completely around your eyes because it will burn if you get it in your eyes. May use it on top of your eyelids only, but use it carefully. If you want totally avoid using it around your eyes.
  6. Apply 3-4 drops of serum onto freshly cleansed skin and gently massage in until fully absorbed. Use patting motions & massage techniques (think of the techniques used when getting a facial, you want to use the same technique the esthetician uses), so massage and pat with the pads of your fingers. Massage serum into skin 30 to 60 minutes before bedtime all over face and the neck and women may put it on their décolletage.
  7. Keep serum in a cool, dry, dark place.

My recommendation is to use this only at night especially if using & adding the Castor Oil. I only used this at night because of having sensitive skin and because I use a different oil blend for the day. If you think your skin can handle more go ahead and use twice a day, always do a skin test. Since this serum is all natural and does not contain any preservatives, it only makes enough to last about two weeks. Vitamin C serum may cause temporary redness and that is normal, but if you have any burning sensation remove with cool water and lower the ratio of Vitamin C powder to Vegetable Glycerine.

When I make this, I note the date on the calendar when I need to make it again, so I know when to make a new batch. After using for two weeks if there’s serum left, I usually just dispose of the contents and make a new batch. I wash the serum bottle really well before making a new batch. After using for two weeks, the serum will lose its ability to properly be beneficial to your skin since there are no preservatives in it.

What I noticed while using this serum:

After 6 days of using it, I felt and saw a noticeable difference in my face.  I had a small white bump on my eyelid and it was gone after 6 days of using this serum.

I had tiny bumps near the top of my forehead and they are gone.  Not sure how long it took for those bumps to go away.

It has tightened my skin, made my face look less puffy, and reduced the few wrinkles I have.  It’s supposed to help lighten hormonal pigmentation, but I don’t have this.

It hydrates my face and overnight gives a healthy appearance to the face.

I enjoy using this serum and how it makes my skin look, and I received more compliments on my complexion.  I have only used it during the winter and spring months as using it in the hotter months did not agree with my skin.


Know it is OK to stop using if you want; unlike medicine we ingest, we can stop using something on our skin more quickly. We may not be able to stop cold turkey with what we ingest, but our skin has more resilience where we can do that. I believe with medicine we can become immune to what we ingest and the medicine cannot properly do its jobs for whatever reason. The same is true of what we put on our skin. Know it’s important to take breaks from using skin products; use something for a while and if you tire of doing it, then stop using it. If you feel as if it’s not working, stop using it. If your skin reacts in a negative, harsh way to something you use, then please by all means don’t use that product.
