Carmen Polanco: I have been working on my CF serum, and I want to add the most absorbable
hyaluronic acid to my serum. Would they emulsify without the polysorbate
80? I would love to hear your professional opinion on several topics, like-
what are your thoughts on more concentrated version of vitamin C- 15% or
20% Do you sell your professional advice, how may I contact you if I have
TheRiteThings: I have a question. Wouldnt the glycerin in the C serum keep the Vit E in
the emulsion? I know sometimes glycerin is used in this way. Then the
polysorbate 80 wouldnt really be necessary and therefore a more natural and
chemical free product. I would really like to make it. But I want to stay
away from the chemicals and preservatives.
Lee Ingrid: Do u care to answer this: "so as an expert do you not recommend to use
Tetrahexyldecyl Ascorbate in DIY serums?" not in ReCverin products?
Elle Dfw: Doug.... Thank you soooo much for your in-depth description of making this
Vit C Serum !!!! I'm on my second or third batch !!!! It REALLY works!!!!
And so reasonably priced! Thanks again !!!!!
Lisa Thong: Hello Doug! I just watched this video and was wondering about the amount
you made -how long will it last for? a week? or month?? Also, isn't better
to make a new batch every week??? please share your thoughts because i am
very interested in making this particular serum! thank you! ~Lisa
HesAPooka: Hi, where do you buy ferulic acid? I'm having trouble finding some.
Melatina77: Can I leave the Polysorbate 80 out and just shake really well before each
Julia L: I love your video. I'm amazed at how little viewers it has compared to
other DIY vit c skin serum videos, but I assume that viewers thinking a guy
don't know what he's talking about women skincare. You seem like a science
type of guy so I gave it a try and so far my favorite video. :) Keep up
the good work. Thanks for the recipe.
kelinhauk: isn't 2.8 pH far that too acidic for the skin?
Elida Denny: THANK U SO MUCH FOR THE RECIPE UR SKIN LOOKS VERY NICE
Tigerdeer: Could you use L-Ascorbic powder in this recipe and if so how much should
you put in? Thanks
Connor Cliche: Hey Doug. I just wanted to say thanks for the how-to! Onto my second batch
of serum I've made since last September (stopped using it for a few
months), but overall loving the results. Cheers to healthy skin mate!
Sarah Child: Gotcha, that's a great idea! I haven't purchased my items yet. But I'll be
doing that very soon. I'll pick up some liquid and powdered lecithin and
see if either one of them work. It's also great that you posted the
ingredients so that I'll have something to follow. Thank you very much for
all your help and I'll get back to you as soon as I can.
Julie C. Francis: Great DIY Serum. Thanks for the post! ooooooooooooooooooyeaaa!
Sarah Child: Thanks for such a quick response. But I thought ReCverin was one of the
main ingredients. (L-Ascorbic Acid) MMmm confused
Sarah Child: This was the most professional presentation and the best diy serum i have
seen. Most other diy serums contain water and spoil. I was just wondering
if i could use 18 drops of soy lecithin instead of polysorbate 80. Once
again, thank you
ReCverin: In my humble opinion, dermarolling is not a safe practice, and you should
not apply anything to your skin (except antiseptic) immediately after. If
you are seeking a way to better absorb vitamin C, I recommend you consider
ReCverin 50/50. This product is the best absorbed vitamin C serum in the
world, and does not require that you puncture thousands of tiny holes in
Robert Williams: You need to study dermarolling further. It is perfectly safe if done
correctly. Been doing it for 1.5 years.
ReCverin: @milagros157 Trans-ferulic acid is a synonym of ferulic acid...they are the
same chemical compound.
STARSWORK: Hi! I really like your video and how professional you are. I like to know
what will this do for my skin? Is it ok for darker skin women?
MightyRoy: Polysorbate 80 is a synthetic emulsifier. It is banned in some food
products. A natural emulsifier like lecithin might be much better.
ReCverin: @avmakeme You said, "Vit C mixed with other substances starts to oxidize."
That depends on the substance. The most important substance in cosmetics
that causes oxidation is water. This recipe is made with ReCverin C which
is anhydrous ("no water"). The ascorbic acid in this product is extremely
stable, no measurable oxidation at room temperature for at least a year!
You will note that no water is added in making the CEF serum. I can't
answer all ur ?s here, write firstname.lastname@example.org for more.
ReCverin: Although glycerin has a slippery or oily feel initially, it is not an oil
and it absorbs within minutes to leave a silky, smooth, non-greasy texture.
Some folks find it absorbs faster if used with a little water or
moisturizing lotion. It is glycerin which allows DHAA to be stabilized in
solution. This is a discovery for which we have received "Notice of
Allowance" for a United States patent. Nobody knows how to make a stable
DHAA solution that isn't in glycerin or a similar polyol.
lilqtxanq3l: When using topical vitamin c products, when should we apply them on? Day or
ReCverin: I occasionally make wine, wish I had more time for it, but ReCverin keeps
me very busy. Thanks for your nice comments!
Connor Cliche: Amazing serum! I didn't know how important an emulsifier and preservative
was! I promptly ordered some Ferulic Acid and Polysorbate-80. This stuff
looks like it's gonna last forever! Any storage recommendations? What's the
shelf life on the Ferulic and PS80?
ReCverin: There is a thorough discussion of vitamin C derivatives at our website FAQs
page, much more than I can write here. Hope you'll visit for info not only
about magnesium ascorbyl phosphate, but ascorbyl palmitate and
ReCverin: @hivespot I hope you will share this with your peers and instructors at
your school...vitamin C is so important for the skin. Thanks for your
ReCverin: Thank you. I hope it encourages you to investigate the health and beauty
benefits of dehydroascorbic acid, and to try ReCverin 50/50.
rngy33: so as an expert you do not recommend to use Tetrahexyldecyl Ascorbate in
C DAVIS: He wants to sell his Recverin product so he didn't answer your question!
Haha! I have the L-Ascorbic Acid and pure vegetable Glycerin on hand so I
can't pay an additional $35 to $40 after shipping just for an already
prepared Vitamin C/Glycerin mixture. If anyone knows how to do this please
let me know!
AV Make Me: This recipe looks brilliant. I just wonder about the oxidation process. I
am a Cidesco Beauty Therapist (Esthetician). I researched & learned that
when pure vit C is mixed with other substances is starts to oxidize
therefore losing its beneficial properties & has a short life span. Where
did you get this recipe & do you use it on you own skin, if so how long &
how long did it take for you to see results from this product? Very
ReCverin: Yes, we use USPS Priority Mail International. This service to Canada is
currently $12.95. Shipment tracking is included.
ReCverin: The serum contains 1% vitamin E, 0.4% ferulic acid, and the vitamin C
concentration depends on which ReCverin product you use: 10% l-ascorbic
acid if you use ReCverin C; or 2.5% l-ascorbic acid and 2.5%
l-dehydroascorbic acid if you use ReCverin 50/50.
dani: Thank you for the response. I do have another question about the regular
ReCverin vs. ReCverin 50/50. The formula in 50/50 absorbs faster (I believe
you said 12% faster), but isn't the concentration of Vitamin C in the 50/50
much, much lower? Can it be effective at that concentration? The Vitamin C
in the regular ReCverin is 15%, and I believe (and may be wrong) this
amount is the least one should use for it to be effective for most people.
Is this accurate?
ReCverin: Yes, the ascorbic acid concentration is the main factor in determining the
pH of the final solution.
ReCverin: At room temperature, ReCverin C will easily last a year without any
significant deterioration of ascorbic acid. At room temperature, ReCverin
50/50 will begin to develop a slight straw color after about 60 days. This
is because the DHAA in ReCverin 50/50 is less stable, but it is more
effective for the skin because it absorbs so much faster. Keeping ReCverin
50/50 refrigerated will greatly increase (many months) the stability, and
it may be kept frozen for at least two years.
Angela T: Hello, can I incorporate D-panthenol in this recipe? Thank you for the
ReCverin: Almost all glycerin you can purchase today is vegetable derived. Distilled
water is preferred in general for do-it-yourself cosmetic recipes that call
for water, but the recipe in this video does not contain water. Vitamin C
solutions that contain water break down much faster than anhydrous ("no
immandrew: do you mean an eye creme? why would you put anything IN your actual eye?!
ReCverin: I'm sorry but I haven't done any tests with hyaluronic acid powder, so I
don't know the answer to your question.
mike tan: Hi there, I am trying to make some CEF Vit C Skin Serum and I could not
find some of the ingredience in the UK.... ReCverin C; Can I make my own by
mixing L. Ascorbic acid and Glycerin??? Folic Acid powder; Can I use Folic
acid(800mcg) tablets, and it contains B12 as well??? Pls advise... Thanks.
CLARA3952: how long is this viable and does it have to be refrigerated thanks
ReCverin: We've tested our products' stability in clear plastic bottles versus dark
bottles, and found no measurable difference. They were all stored indoors
under normal room lighting. The effect on the vitamin C in our products of
18 or 24 hours exposure to room lighting is negligible. I wouldn't put the
bag in direct sunlight, mostly because of the heat rather than the light,
but also because we haven't tested the effects of extremely strong light.
Thank you for the inquiry and viewing the video!
ReCverin: The vitamin E is an oil, some people don't like the feel or appearance it
gives the skin. For you, I'd recommend using ReCverin just the way we
provide it rather than mixing in vitamin E.
coperniciaTalent: the emulsifier should have lower molecular weight than the sebum in our
skin right? (like jojoba oil) Is that the cae of lecithin too?
