Peter Thomas Roth Potent C Serum 1 oz

For some reason, most vitamin C serums (even the more expensive ones) cause my face to turn orange, no matter what I do and I've tried everything over the years but this one does not!! I will continue to use Peter Thomas Roth vitamin C serum!

I love this serum of vitamin C or THC, I have been using it for 2 years it has transformed my skin tone, now it is even, no more brown spots... the key to any vitamin C is the consistency. Just dont tell anyone that Walmart has it cheaper than ULTA, please?

It does firm my jaw line, helps in neck lines, right away l started notice the changes, and Walmart is the only safe place that l can buy it a very good price.

Now that I have found this product at Walmart, I will NEVER run out at their discounted price!!! I absolutely LOVE everything about it, except the faint odor ... that goes away quickly though! The results are worth it!!! My skin surface is smoother, I have noticed skin discolorations fading ... my fine lines are disappearing ... I also use it on my neck

I started using this serum several years ago and I really think it helps keep my wrinkles under control. it just takes a pump or two of the cream to cover your face and neck so it the bottle lasts a long time. it goes on smooth and sinks right onto your skin. I've tried other vitamin C serums but I always come back to this one.

I was advised by reviewer that Peter Thomas Roth Potent-C Power Serum has a concentration of 20%Vitamin This product has 20% C-THD ascorbate, 3% E-Antioxidant and 2% Ferulic Acid. It has a higher concentration of each of these ingredients than SkinCeuticals CE Ferulic at about half of the price. Not only that, it has a squirt top that preserves these ingredients better than the eyedropper on the CE Ferulic bottle, which allows the ingredients in the bottle to oxidize.

Beware - Bought this from Walmart as the price was lowest I've found anywhere...But as with any "great deal" from an unknown seller, I was suspicious when I found the box was open and the top of serum bottle was unscrewed. Really?? This makes me think this product was tampered with. Thinking of returning. I was better off paying more for an unopened product!!

Bottle around the cap was gummed up with product and sticky. Looks as if it had been used / returned from someone else and reshipped with out checking. Very dissatisfied. First bottle I had ordered months back was like brand new, that is why I reordered from WalMart. Need credit to my account

BE AWARE . Im thinking that this item is fake .It has ZERO effect, didn't do 1% of what it promises. I have use PRT brand before its amazingly effective. But this one i guess is not their authentic product.be careful and purchase from the original PTR site or Macys

Usually I'm a huge fan of PTR. However this stuff. After 3rd use broke out in a rash all over my face. Had to go to dermatologists 2x for medicine to clear up what appeared to be a burn. I've used his Camu Camu bit c serum in past with no issues. This must be a different formulation
