Victoria Feru: 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!
Doug Kitt: I'm glad you like it, thanks for your nice comments.
BumbleBearCrafts: Thank you fr sharing, I enjoyed your video and can't wait to make my own CEF and CDEF serums.

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?
GloriaHieser: Great video and wonderful information. Thank you! I will definitely make my own CEF serum following your recipe. :)
Protected1: Is there a natural substitute for the polysorbate?
Doug Kitt: Thanks!
Monalisaknew: Thank you so very much. Extremely clear and a pleasure to watch.
Cesar Armando Escobar Posada: Skincare companies would like everyone to give their products a try to demonstrate how good they are.
Have you ever noticed the cosmetics area set-up in your neighbourhood mall offering free samples?
Well you must check out this website that will send free test products to your home, its the best way to get free skin products :)
You can get them here bit.ly/15PM8rW?v=piyjq
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.
KimmiK BoutiK: Hi there. Thank you for sharing this video. I would like to know if Hyaluronic acid in powder form can be incorporated. If so how much? Many Thanks
ReCverin: Thanks for the nice comments! I'd suggest viewing the videos I refer to below for a basic understanding of what dermatologists believe about topical vitamin C, even though one of the doctors makes an erroneous statement about the oxidized form of vitamin C. You will see that Vit C is good for everyone, no matter what their skin color. ww.doctoroz.com/videos/1-secret-ingredient-youthful-skin-pt-1 and ww.doctoroz.com/videos/1-secret-ingredient-youthful-skin-pt-2
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?
Angela T: Thank you.
ReCverin: I haven't tried so I can't be sure. According to Wiki, panthenol is slightly soluble in glycerin, so it is likely that some amount of panthenol can be incorporated in this recipe.
Angela T: Hello, can I incorporate D-panthenol in this recipe? Thank you for the video!
ReCverin: FA would be described as "slightly" or "sparingly" soluble in glycerin, similar to its solubility in water. The amount added in this recipe at 0.4% is soluble, but is very close to the maximum that will dissolve. That's why I've emphasized careful measurement, dispersing it well, and allowing it to sit long enough to dissolve. It's also why commercial CEF serums contain only about 0.5%, since their base is mostly water. Thanks for your inquiry.
19651971199119972000: I thought ferulic acid wasn't dissolvable in glycerin?
ReCverin: We ship to all countries, and we charge only the current USPS Priority International shipping rate. Furthermore we discount the shipping charge by $5 on international orders over $50. Current (April 2013) shipping to Germany is $23.95, and $18.95 on orders over $50. Sorry, but I cannot post our trade secrets for manufacturing ReCverin products.
Faredin Agaj: Hello, can i make this serum with these products:
Natural Vitamin E Oil - tocopherol - 50ml
Vitamin C (L-ascorbic acid) powder pure- 1.8oz / 50g
NOW Solutions Glycerine Vegetable, 16-Fluid Ounces
Polysorbate 80 - 4.2floz / 125ml
I can find these products in Germany, bcs i can not get them from usa!!
ReCverin: If you use this serum at night, there is no point in adding FA.
I believe the brand you mention uses a chemical derivative of vitamin C called Ascorbyl Palmitate. I recommend that you read the discussion of vitamin C derivatives on the FAQs page of our website. The reasons for not-using various derivatives are many and complex. These YouTube comments only allow 500 characters; there is not enough space for a proper discussion here. Thank you for your comments!
ReCverin: We recommend 3-5 drops for a surface area of skin the size of the face. Thanks for your interest!
jan jones: very informative video, Two questions: 1. Why use sunscreen ingredients when used for night? 2. Dr. Perricone uses Ester C because is is less harsh on the skin etc. Any reason for using ester c or others? Thanks for your good work
Judy Weinstein: Great video, if I just want to use the ReCverin 50/50, how much do you put on when you apply it directly from the bottle to your face? Thanks!!!
ReCverin: As you have already discovered by reading the FAQs on our website, Tetra is a synthetic, man-made derivative of ascorbic acid. It can provide very little (if any) of either of the natural chemical forms of vitamin C because of its gigantic molecular size and the need for enzymic action to remove the unnatural chemical attachments. I doubt that it is harmful, and if you like to put it in a DIY recipe for some other reason (i.e., texture), by all means do...it just won't provide much vitamin C.
ReCverin: Thank you for the nice comments about the info on our website...I am always very pleased when someone recognizes the effort we have made to provide comprehensive, truthful information about vitamin C and skin care.
Robert Williams: yes very safe...go to owndocdotcom for best info
Robert Williams: You need to study dermarolling further. It is perfectly safe if done correctly. Been doing it for 1.5 years.
rngy33: i have visited your web side, i am impressed by your research! i definitely will try both serums!!! thanks for sharing this video. have you ever considered to create multivitamin "skin food" serum? Since you have all the equipment and lab and knowledge why stop on only 2 products.
I like to make my own skin care--and i am too ordering my Ingredients like Co Q10 and Tetrahexyldecyl Ascorbate from Lotioncrafter :)
rngy33: so as an expert you do not recommend to use Tetrahexyldecyl Ascorbate in DIY serums?
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 water") ones.
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 your skin.
ReCverin: Yes, the ascorbic acid concentration is the main factor in determining the pH of the final solution.
ReCverin: Ferulic acid is a weak sunscreen. The polyoxy- compound is an emulsifier to create a stable emulsion of Vitamin E oil. I understand your confusion about vitamin C forms, and suggest you visit our website and read the FAQs section. It discusses the many forms of vitamin C in much greater detail than can be done here. Thanks.
missy elliot: Is using vegetable glycerin and distilled water a no no?
missy elliot: Is this recipe safe to apply straight after Dermarolling?
missy elliot: Does it depend on how much Ascorbic acid etc etc used to determine the PH balance?
Look forward to your reply! :)
missy elliot: Thank you for such an amazing video! - I am a little confused about the dry ingredients you've used though (Ferulic acid and Poloxyethylenesorbitan Monooleate). Can you please tell me what they are and what benefits they have? - Also, would you recommend Camu Camu powder and Ester C? - Is Ester C powder the same as L-Ascorbic acid/Vitamin C powder? What would you suggest about Tetrahexyldecyl Ascorbate? There are many suggested ingredients for Vit C serum. I am officiallyconfused.
ReCverin: I see...sorry I didn't help. The video was made in spring of 2011, prices were what I paid then; I haven't bought FA since. FYI: FA adds a weak sunscreen to this serum, nothing more. You might consider leaving it out and just using a good sunscreen on top when you need it.
BTW, the ReCverin prices are still current as of Jan. 2013.
83msmoon: Thanx . I found some websites but all of them are expensive. In your video, you said got 1mg of ferulic acid for $2 .that's way I asked you about the website.
ReCverin: I bought this from Lotioncrafter, but there are many other online stores that sell it. Just Google DIY ferulic acid.
83msmoon: Hi.. I like your video. Can you please post the websit for the ferulic acid, I really wanna buy some of this acid. Thanx
ReCverin: One practical thing to note, however, is that AA absorbs very slowly, so it is good to put it on and leave it there as long as possible. If you apply a serum just before you go to bed, and then most of it is wiped off on your pillow slip, it can't do you very much good.
ReCverin: You describe making ~11 mL of serum per week. If you use 10 drops a day, you'll use 4 mL and discard the other 7. One bottle ReCverin C at 10 drops per day will last 120 days. You will make 17 batches in that time. Many would think the trouble alone is worth $1.71 per week. BTW, your recipe has flaws; it is very hard to dissolve 1 tsp AA in 1 tsp water; undissolved AA won't go into skin and is gritty; if it did dissolve, your recipe'd be 35-45%; 10-20% absorbs better. Advice: Use 1/2 tsp AA.
trastokorn: 29 dollars for vitamin C is in my opinion too expensive. I bought 100 grams of pure crystals in Germany for a couple of euros. Mix 1 tee spoon of powder vitamin C (aprox 5 grams) with 1 teespoon of pure water and 1 tee spoon of glycerin. thats it. it will last you for a week tops
ReCverin: A bottle of ReCverin C contains 60 mL glycerin and 6 grams l-ascorbic acid. But I won't share our trade secret processes that are used to make our pure, crystal clear vitamin C solutions. Even if you did know those processes, you almost certainly do not have the necessary equipment or supplies, and you would find that it is not economically feasible to acquire them for the purpose of making individual amounts. Why not let us do the hard part?
SuchaCaligrrl: I have l-ascorcic acid in powder, and a bottle of vegetable glycerine if i wanted to use that how much would I need to use?
ReCverin: The CEF serum will have the same stability characteristics as the ReCverin product from which it is made. Please refer to the "use and storage" guidelines on our website for guidance on the expected stability, and be aware that cool temperatures greatly extend the stability of ReCverin 50/50.
yay wee: I need to know if the finished product has an expiration date.
