Peter Thomas Roth | Potent-C™ Power Serum

Update: after using this serum religiously morning and night on both my face and neck for 5 months, I did notice my skin tone looks more even and brighter (maybe 5 to 10% improvements). I didn’t notice any lightening of my hyperpigmentation, dark acne scars or sun spots.I used 3 pumps to cover my whole face and neck day and night. So I ended up burning through 4 bottles of this vitamin C serum. It’s interesting that many YouTube MDs always comment on THD ascorbate as being oil soluble and can penetrate deeper into the skin. However, there aren’t that many studies to prove this. I read some chemist blogs and the conversion of THD ascorbate to ascorbic acid is only 16% in cells. This means you are getting only about slightly over 3% equivalent of ascorbic acid in your skin. I’m guessing that’s the reason why I don’t get the dramatic results compared to the Revision brand with 30% THD ascorbate (close to 5% equivalent in f ascorbic acid conversion) will continue to search for other vitamin c derivatives since my skin can’t tolerate the L ascorbic acid formulations. My next one to try is the DS laboratory with the ethylated vitamin c. I still give this vitamin c serum 5 stars and it’s a good beginner vitamin c serum to try if you have sensitive skin.Original review:I tried so many different types of vitamin c, Cerave, Skin Ceuticals, Glow Recipe, Mad Hippie, 100 percent pure, L’Oréal, Neutrogena, No7 capsules, Drunk Elephant. All of them either burned my skin and caused rash from the L-ascorbic acid formulations, or they are not potent enough for me to see any differences. The only vitamin c that’s comparable to this one is the Revision THD 30% which is about $35 more than the Peter Thomas Roth brand. While I do love the higher % from the Revision and it does not cause any irritations with much faster results, the Revision brand’s new packaging is so horrible and I’m not able to get every drop of the products out from the horrible tube design.I love the PTR brand because the packaging is much easier to dispense every drop of the product. It also doesn’t pills and layers well with other products. No artificial fragrances. It does have a natural vitamin C smell and it smells like iron rust. It’s a creamy lotion like consistency like the Revision brand I love with cheaper price tag. The only down side is you see good results but not as fast as the Revision brand since it’s the 20% concentration.The other one I tried was the Herbivore Vitamin C serum that has 15% THD ascorbate. I would say this one is a pass for me because not only the concentration is lower, also the tumeric scent comes off quite strong for me when you first apply it on your face. Also the bottle is transparent not blocking off the light (I’m just being OCD at protecting my vitamin C serum).

wonderful creamy feel - not thin and watery like some serums. Whether it works to restore skin cells remains to be seen with a little time. But the "feel" of it on your face is very moisturizing.

I've TRIED other Vitamin C serums, but I've had bad effects from many of them (such as orange skin and orange break-outs). This product feels very good, makes my skin look bright and slides on just as a serum should. It's pricey, but because of break-outs with other Vitamin C serums, it's worth it to me.

This seems like it's legit, based on the smell. I do not know if I received a full product - It does not come with any plastic outerwrap and the pump top on my bottle was fairly loose. No product leaked out, but it was definitely not on tight. I think some of the other reviewers mentioned not getting a pump, but the cap is on so snugly that I thought that I did not receive a pump. Once you get the top off, you can see the pump applicator. Smells like campfire, so I think it's authentic. A sample that my niece gave me seemed to do wonders, but this product did nothing for me. Likely will not purchase again.

I can't convince myself this is worth the $$$. At 1 pump per day, the bottle will last around 4 months. But it has a weird smell that doesn't sit quite right with me. I will finish the bottle but it's highly unlikely I would repurchase it again. I will likely return to my previous Vitamin C pictured.

Works well, I use it every other day to avoid skin irritation.

So I’ve purchased the Peter Thom’s Roth Potent C Power Serum twice now and love the results I see in my mirror, even skin tone for the win. It’s not drying and plays well with other products, the scent was much more noticeable on my second purchase though. As much as I love the product I don’t think I can justify the price as is the case with many skincare products lately, it’s just over the top.

Don't work the way it's said very false advertisement
