Good for the price

I was looking to not spend too much on a vitamin c serum. This was decently priced and it is working well so far. It’s a little sticky at first because it takes some time to dry.

A little goes a long way

I wanted to try an alternative to a more expensive C serum and I was pleased with this product. First the price is right and a little serum goes a long way and gives the same brightness and exfoliation as the more expensive version. Change is difficult but this will be a good alternative choice for me.

If you can overlook the smell, nice product!

Ever smell hot dog wrapped in old, hot tire? You're about to smell that exact combination after your first application of this serum. Good news is, either you will get used to the smell or the smell fades reasonably quickly. My esthetician recommended this. I do like how it spreads nicely, not too greasy. It tingles a bit when I put it on and I think I've had some success with brightening.

This Vitamin C Serum is Really Nice!

I like the way this product is dispensed with a pump and comes out more like a lite lotion than a liquid serum. It has a vitamin C scent, but I don’t find it overwhelming. Also, it is helping with my hypopigmentation spots, which is a little bit of a different problem than dark spots.

Great Vitamin C

I love this Vitamin C. It has great ingredients and doesn't irritate my sensitive skin. It also looks good under makeup. Since it is a cream it isn't as sticky as other Vitamin C serums I have used.

Nice Serum

I previously used another similar serum but it was thinner and you used a dropper. I do like that this is more of a cream vs liquid. The liquids in the dropper can be messier and prone to spills. It seems to be effective based on the results I'm seeing.

Helps to even skin tone and decrease pigmentation

I was looking for a product that could help me to fight pigmentation. And this serum really works. It made my old spots less bright, erase some of my new sun spots. So far I am really impressed! I tried different C serum from another popular brand with 20 percentages concentration of Vitamin C and my skin could not tolerate it, it dried my skin out and was irritating. This serum does not irritate my skin. Peter Thomas Roth serum makes my skin tone more even. Also 1 pump is enough for the whole face which is not a lot. I don't really like the fragrance of the product, but I can handle it because it smells only while applying. It smells more like ferulic acid which is fine because it contains ferulic acid :)

Favorite C Serum

I like the consistency and it’s easy to apply. I love the packaging I feel the product ingredients are not compromised. When I use this product my skin Is firmer and looks brighter. It does sting a bit but it does subside. I have definitely noticed a difference in my skin since I’ve been using it ….I’m on my 5th bottle!! I use it every morning!!

Repeat Buyer

I've been using this product for a couple years. It's my favorite Vitamin C serum. I tried the SkinCeuticals brand recently to see what the hype was about, but I came back to this. My skin type is dry/sensitive and this really bring the hydration plus the added benefits of Vitamin C.

Power packed

I have used a vitamin C serum on my face every morning for over eight years. This has resulted in the disappearance of brown spots, as well as smoother and brighter looking skin. I saw this one in a recent sale here on Lovely Skin and wanted to give it a try. It has a really nice feel and texture, and absorbs easily into the skin. The reason I deducted one star is that the smell is identical to that of the pricier Vitamin C serum whose name I don't think I am allowed to mention. Some people will not be bothered by this, and may not even notice. I would probably buy this again, in spite of that one quibble.

Peter Thomas Roth Potent-C Power Serum

Thus far, I really like it. I have used 2 different vitamin C serums with the L-ascorbic acid and did not like how it oxidizes. After researching the best form of vitamin c and effectiveness for brightening, I decided to give this product a try It contains 20% THD Ascorbate. (suppose to be a more stable and potent form) as well as higher percentages of vitamin E and Ferulic Acid than other brands. I do feel a light tingling with this one which I like. Have not used it long enough to see any brightening results. Definitely like that it's more of a lotion base that you can pump.

So far, so good

This is my first “C” serum purchase. I use other PTR products, so decided to start here. I do see some lightening of age spots and general brightness after about three weeks of daily use. I have not noticed any irritation, and use in morning under daily moisturizer w/spf. It is a bit sticky, so needs a few minutes to soak in. I’m 50 and also use glycolic acid and retinol in my daily routine.
