Decreased Quality - Do Not Purchase

TL;DR. Packaging opens up and leaks. Product does not stay emulsified and is greasy not silky. Find an alternative Vitamin C. I've purchased this product for years and have noticed changes with time. However, my latest was the last. The packaging is poorly constructed and unscrews constantly. The first package was leaking and I had to return it. The product itself is separates and does not stay emulsified. I have to shake it before I dispense it to mix the oil and creme together, however there are no such instructions on the bottle. It seems the quality of the ingredients have decreased. Really disappointing.

Another out of the park transformer!

I finally tried the PTR C serum. In three days I noticed a difference. My skin felt smoother. I still have some mild sun spots , which will take longer to disappear. I expect that. I just didn't imagine such a difference in under a week!! This is definitely a HIGHLY recommended product!

I loved the old power serum. It was clear and glided on my skin. Whyyyy if you say it's the same product would you not only change the packaging but also the consistency from a clear hydrating serum to a white thicker serum. Do not like the feel. You did the same thing to the wrinkle resist power serum to these white seeums. No longer a fan of this whole new set of serums. They used to make my skin glow. No longer....the consistency is different. On the hunt for new products.

Stinks!!

Yikes it smells so bad! I tried it for the first time 6/10/25 . Smells like rotten eggs plus it came out of the bottle really thick and a wierd color yellow. I still could smell it once i put it on. Had to go into a public bathroom to wash it off.

Unpleasant smell

The odor of this product line is very unpleasant. I thought that this would be useful for my skin but the odor is offensive. I will be returning for a refund as I cannot use the product.

In love with this serum

I have owned a lot of serums throughout my adult life. PTR Potential-C is by far a superior quality than the rest. It starts with the beauty of the bottle itself, the sublime experience of rubbing in the serum. It is exquisite. The light smell and ease of application are divine. The results can be seen almost immediately. I will never use another serum again.
