I love this product, but this is the second time that my pump mechanism broke on this. I already got a replacement from them the first time and now I feel embarrassed to have to reach out again. I own all their products and this is the only one that gives me problems with the pump. I now had to transfer all my product to another bottle to be able to use it and I shouldn't have to do that for the cost of this. I see by reviews this is an ongoing issue but they aren't addressing a real fix, only replacing it and it just happens again.

I've been using this product for many years and it continues to help my skin stay youthful,

I've added this to my rotation of serums to use at night with the polypeptide moisturizer. I mix it in as a "smoothie" and it goes on well — absorbs quickly and lightweight serum. It's gentle to use and my skin has been reacting well to it.

Like the way this feels on my face, resurfacing or something close to that is how it feels.

My skin looks and feels amazing

Bought this from Ulta today, and it is so watery it was hard to even put on my face. I read such good reviews about this I am super disappointed

At this point I've tried every single DE product & this is my favorite. It's tingly, it works, it's not irritating. Repurchased.

I've used it faithfully twice a day for two weeks, with no noticeable improvement yet.

Amazing program, smoothes out my skin and makes it glow.

I cannot get enough of the Protini Powerpeptide Serum. I've noticed such a huge difference with the appearance of my skin and the texture. It's helped with my blemishes, dark spots, ance, and smooth out wrinkles. It's a must have!
