Review: Only 3 days in but so far, so good! - I feel a bit silly writing a review for a beauty product that I've only used for a few days but I made the serum everyone's talking about (CEF serum) with the three products here (when you scroll down and it says, "buy all three") and call me crazy but I think it's really making a difference! I saw my mom today (when I gave her the one I made for her, that SHE requested) and I told her when we were in the bathroom together while shopping, "I'm sure it's just wishful thinking but I really do think this serum is making my skin more radiant!" Now, you don't know my mom, so you couldn't possibly understand how shocked I was when she said, "I think so, too!" I almost fell over! My mom is NOT a fan of ANY of my homemade concoctions! She has no use for my essential oils or any of the 20+ toiletries I regularly make with them (not even my hair-growth serum and I've grown my hair almost twice the thickness and over 10 inches in length in less than 7 months!). She IS impressed with this! Even my 22 yr old daughter wanted some (and she sees me every day)! I have severe acne scars, moderate-to-severe rosacea, have been a heavy drinker for 15 years, have been a heavy smoker for 25+ years, and I swear- I'm starting to get my radiance back! I haven't seen any improvement in the scars yet but it's only been THREE days! My huge pores are noticeably smaller, my skin is starting to take on a healthy glow, and if I'm not mistaken, I surely feel that my complexion is starting to even out a bit! I'll update later when I've used it for a while but so far I'm VERY impressed! I will add a couple of notes that I haven't seen in the reviews of the CEF serum, though (and none I saw put any Vitamin E in theirs anyway so technically not CEF [Vitamin C, Vitamin E, Ferulic Acid]). (1) When I made the first one for myself, I mixed the Ferulic Acid (with 91% rubbing alcohol, not vodka) and added it to the bowl before adding a pinch of baking soda. When I mixed it for my mom and daughter, though, I mixed the Ferulic Acid and added it to the bottle, not the bowl I was using to mix everything else, and the baking soda caused a fizzing reaction. I hope that doesn't mean the Vit. C was completely eradicated by the reaction but in any case, I would avoid that by mixing and adding the Ferulic Acid to the mixture before adding any baking soda. (2) No one warned me that Hyaluronic Acid would gel up IMMEDIATELY, making it practically impossible to get the mixture into the bottle. I found it easiest to add the mixture to the bottle first, THEN, with a COMPLETELY dried funnel, add the Hyaluronic Acid last and shake it like a crazy person. Funny thing happened when I did it that way too, though; every time I took my finger off the top of the bottle, it spewed a ton of air and a little spray of the mixture a few times. I can't help but wonder how others are doing this- mixing it first and getting it into the bottle, or adding it later without exploding bottles. If you DO decide to add it last after the mixture is in the bottle, please DON'T put the lid on right away before shaking it! I imagine after a few shakes there would be quite a bit of pressure built up in there! I don't know if refrigerating the mixture is necessary (I read somewhere it was for one of the ingredients but I can't remember which or why now, I think to help the Hyaluronic Acid to gel) so I put them in the refrigerator overnight. All of mine gelled well, even though I only used about half the Hyaluronic Acid on the second two batches because mine is a bit tacky when I first apply it. I'm okay with that bc I don't wear makeup very often but my daughter preferred hers to be a bit less thick so she could apply moisturizer and makeup sooner without waiting for it to dry. Hope this helps, and if anybody has any advice to add or questions to ask, please comment!
Review: SO WORTH IT - I've been using this for 3 weeks, yesterday when i looked in the mirror, i did i double take... IT'S WORKING, IT'S WORKING! Whenever i buy new products I'm optimistic at first, then after several weeks and no changes, I'm left disappointed. I'm so happy that I finally get the excitement of something actually working! My dull skin is brightening, sun spots are starting to disappear, tighter, smoother skin, even the hallows under my eyes seem to be thickening up. I always drop out too much, so I also use all over my hands, they are looking much younger. And I use on my neck and decollete, skin is much brighter and smoother. Recipe: *1 tablespoon vitamin c powder *4 tablespoons water *A few small drops of ferulic acid powder dissolved in an alcohol base. This is optional and will help stabilize the vitamin c and add additional antioxidant properties. *A small squirt of glycerin *½ tsp hyaluronic acid powder Add the vitamin c, ferulic acid and glycerin to the water first and once everything else is dissolved, add the hyaluronic acid powder. This will make about a 10% vitamin c solution. It will chunk up at first. You must leave it in the fridge overnight to disolve and settle. I mix my serum in a small plastic container, then after it settles over night in the fridge, i transfer everything into an old, cleaned out, glass serum bottle with a dropper. I don't want to keep it in the plastic container and dip my fingers in and contaminate the serum. I leave my bottle in the fridge after every use. Based off the reciped I'm using, it makes about 2 weeks worth of serum when using a generous amount twice a day. I wear the serum alone during the day and a retinol moisture on top at night. This stuff is amazing! I'm so excited to see more improvement! Photos are from day one and after 3 weeks.

## Questions & Answers

**Q: Can you add more vitamin C to make it a 60% solution? What would happen?**
A: If 20% is good, more must be better, right? Not necessarily. A medical university that did studies on the percentages of vitamin c applied topically concluded that 15% is the minimum to see results and 20% percent maximum for best results. Anything under 15 is about useless and above 20 won't absorb into the dermis. I've used 30% before but got no better result than a 20%. I don't think 60% would be beneficial and may strip your skin or even damage and or discolor it.

**Q: Can you add this to a non water based formula? Such as beeswax and oil based creams?**
A: Mix it with your water or try these alternatives rosewater, aloe vera juice and then mix it in to your cream lotion etc.

**Q: What is the expiration and what is the safest place to keep the unused portion?**
A: As long as you seal it with no or little air in the bag you should run out way before it ever expires. I've been on the same bag for about 6 months or so and its as potent as the day I bought it. I keep it in the bag it came in along with my other diy products in a paperbag under the bathroom sink cabinet.

**Q: Is this a non-GMO product?**
A: Yes, this is non-GMO

### ⭐⭐⭐⭐ Perfect for my needs, leftovers store well.
*by L***R on January 19, 2017*

I mixed this with a little distilled water, Art Naturals aloe vera gel and vitamin e oil to make a serum for my skincare routine at a fraction of the cost of a store bought product. I keep the serum and the left over vitamin c powder in the fridge. My skin tingles a bit when putting the serum on, just for a minute, so I know it's potency is intact. The packaging of the powder is fantastic as it reseals airtight (if you close it right) and it is not transparent so the light doesn't degrade the product prematurely. I didn't give it 5 stars because this is the first time I have used Vitamin C powder and I have nothing to compare my experience to. But I'm very satisfied and would buy this again. UPDATE 2/20/17: I've been using the serum every other day for almost 6 weeks, and I do notice an improvement in the appearance of my skin. Nothing earth shattering, but a definite improvement, skin is a little tighter, pores are a little less noticeable. I'm super pleased with the outcome. I could probably use it every day without irritation.
