The future of vitamin C has arrived, and it's ready to moisturize. Potent-C Power Serum is formulated with THD ascorbate, vitamin C, vitamin E, and ferulic acid. This rich moisturizing serum helps reduce the appearance of dry fine lines.

How do I use it: Apply one to two pumps to clean, dry skin. For best results, use twice daily on face, neck, and back of hands. For external use only.

From Peter Thomas Roth.

Rated 5 out of 5 by from A Step Up! Is it too early to ask for this in a super size? 1 oz is just too small, since it's great for eyes, face, neck and chest. I even like to use it, morning and night. I don't always do that since I go through it too fast if I do. BUT, ideally, QVC will soon offer a super sized version and I will be able to use this to my heart's desire. I also like PTR's Camu Camu serum. But, this is my new favorite. It's a multi-tasker that spreads easily and layers well under other things. I was already taking great care of my skin but this has really helped my texture. TIP: this has strong, effective ingredients. Therefore, make sure you're applying it to dry skin, not damp, or your skin may become irritated.

Rated 4 out of 5 by from Great Staying Power I really like this product, it stays on all night no matter how much I toss and turn. So that’s great! I need to use a little longer for results but I do not like not having it on.

Rated 1 out of 5 by from Not for me All I got from this product was a terrible rash on face, neck, chest; where ever I put the serum. Needless to say, I am sending this back.

Rated 2 out of 5 by from Greasy and sat on skin I did not like this product. Used it twice a day for 10 days and made my pores clogged. Had more blackheads and some pimples on my face and I never break out. Not for me. Maybe for someone with really dry skin or people that use Vaseline for a moisturizer.

Rated 5 out of 5 by from The Holy Grail of Skin Care!!! I have been using multiple PTR products for a while. Love them all, but The Potent-C is UNBELIEVABLE!!!! I have used all kinds of skin care through the years and have never seen such immediate results. The first thing I noticed was the improved texture and softness of my skin. The next was the glow!

Rated 5 out of 5 by from The best ever This is the best Vitamin C serum that I have ever used. My skin is brighter, firmer and I can see an improvement in my fine lines. I absolutely love this product. Peter please don't ever discontinue it.
