    I would be happy to address all of your questions.  

    SABRINA Collagen Rx Plus anti-aging face cream is an excellent product.  We offer a money back guarantee because we fully believe in our face cream, and it is important to us that our customers are 100% satisfied with their purchase.  We are so confident in our product and it’s efficacy, we are offering a 30 day free trial.  People can order the product and try it Free for 30 days.  Even the shipping is Free.  If they love the product they will be charged after the 30 day trial.  If they decide they are not happy with the product they can return the jar and unused cream and they will not be charged.  To me, that states that we absolutely believe in our product, and we are confident that our customers will love it as well.

    @ngarayeva001 That is why I am so curious why people don’t just return it. 
    Btw @Ngarayeva001, you are correct!  My product is everything I claim it to be and no one has ever returned my product.  I would like to know how you gained that information. Also @ngarayeva001 why did you use hashtags in your first post in this thread?  Did you read the terms and agreement section when you chose to join this forum?  

    Hello All,
    I recently found this product https://sabrina-beauty.com/the-science/ with a pretty generic ingredients list (except for misspelling “tocopheryl acetat”). The manufacturer is making really bold claims about using “nano-size collagen” that “penetrates” through stratum corneum and “rebuilds lost collagen”. I am staying more than sceptical, but very curious about the opinion of the professionals on this forum. What are your thoughts on ingredients like this “nano” collagen and ultra-low molecular weight hyaluronic acid? I understand that skin is a natural barrier and this product won’t restore lost collagen, but is it worth it to pay more for ingredients with lower molecular weight?
    Thanks in advance!

    @SJane I see lots of Marketing, no Science.
    I have never seen a prohibition on the use of hashtags. I have never seen the moderator delete a post for this reason. @Perry?
    Could you address;
    • The manufacturer is making really bold claims about using “nano-size collagen” that “penetrates” through stratum corneum and “rebuilds lost collagen”.
    • “Collagen Rx Plus uses Nano Technology to shrink the Collagen Molecule so it can easily be absorbed into the skin.”
    These are unauthorized drug claims.

    I probably missed something about hashtags. @SJane, I am sure your product is an excellent product 🙂 You have a right to believe in it, and we have a right to stay sceptical. There is no legit study that proves that topical collagen does anything except for moisturising skin. If you can provide that study I, and I am sure everyone in this forum, will be happy to change our opinion. But going back to the claims, what is the size of your collagen in dalton?

    @SJane Believe me, the FDA monitors claims and will intervene. I would look at your claims before you get a warning letter.

    @SJane, @ngarayeva001, @Microformulation - There is no prohibition on hashtags on this forum. Of course, if they become annoying we might start removing them but it’s not a problem at the moment.
    I’m curious what is meant by “the terms and agreement section” on this forum.  Where was this found?

    @SJane confidence in the product is a great thing to have, why would the customer believe you if you do not believe it. However none of your available “Science” is proper.

    As it is mentioned earlier - Nano does not refer to the size of a molecule but the size of a particle (or agglomerate of particles). With that said it is also impossible to shrink a molecule.

    I bought the Christie Brinkley trial cream, we came out in a rash & it was so hard to send it back, the return shipped cost almost as much as the cream. It is a scam!!!!!!

    Oops, they corrected tocopherol acetate correctly. Good job, SJane!

    Yes, but they have other errors in the INCI Deck.
    Advance Moisture Complex is not an approved designation.
    “Marine Collagen” is not the approved nomenclature.

    I might be missing something but tocopherol acetate is a second ingredient. Is there any reason to use it at a concentration higher than 0.5%?

    Probably the only material above 1% is water.

    No Vitamin E is usually used at 1% so they may have written the INCI names in the wrong order?

    Oh wow! I think you are right @”Dr Catherine Pratt” . It didn’t even came to my mind, I thought it’s just a weird formulation. Now I noticed that other ingredients are also not in descending order! It’s very unlikely that they added more hyaluronic acid than dimethicone and emulsifiers.
