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
Nick Doe: How would one make a 20% Vit C solution?
Sandra G.: Are any of the ingredients or (vitamin E) comedogenic?
Sandra G.: I'm wondering if any of the ingredients are comedogenic, like the vitamin
Nick Doe: Do you ever mix your own Vit C?
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.
Sandra G.: What are the ingredients in ReCverin?
Nick Doe: You do a good job
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
