Peter Thomas Roth Potent C Collection Review

Peter Thomas Roth’s latest skincare line is based around THD Ascorbate which they claim is 50x more powerful than traditional vitamin C. I think the 50x claim is a little hyperbolic but THD (short for Tetrahexyldecyl, say that 5x fast) Ascorbate does have some clear benefits, it is more stable than Vitamin C and is also more lipid soluble than vitamin C which means it is able to penetrate the epidermis better and reach the dermis to boost collagen production. This line is supposed to help treat fine lines and wrinkles, improve skin firmness and elasticity and also help correct uneven skin tone.


When I was sent this collection by Influenster, I was over the moon and couldn’t wait to put it to the test against my PIH and my developing smile lines, but before we get fully into the reviews, I will give a spoiler, I had very mixed emotions.

First up we have the Power Serum which retails for a whopping $95 at Sephora, this was the product that I was most excited to test out because I love a good serum but was interested to see if it was worth the high price point.A3F601A8-8173-46D9-BD3E-6A26C584BF0B

Unfortunately a few days into testing, my skin firmly told me that it was not feeling this serum at all. I developed a ton of closed comedones all over my face in areas that I don’t typically break out in like my forehead and jawline. After I saw that I immediately stopped using the serum because it just wasn’t worth sacrificing all the improvements I’d seen in my skin’s texture just to give it a full 28 days if I was all ready reacting on day 3.

I don’t want to completely write off the serum since most people had glowing reviews for it online, so if you can get past its Vitamin C “meaty” scent I’d tell you to give it a go, but its a major no for me.

Next up is the Power Eye Cream which retails for $65 at Sephora, this product came with it’s own bag of issues (though not as bad as of a funky smell).6C23C46C-1EA1-49AF-831D-E9C7D8F6CCF7

The first thing I noticed when I started using this eye cream was the burn! Without fail for the first 2 weeks of testing I couldn’t use this without my eyes watering, and to be honest I really considered discontinuing use of this too. However, along with the burn, I noticed that my normally dark under eyes, appeared significantly brighter. I kept using it and found that applying less than the normal pea size and not going as close to my waterline helped me avoid the burn but keep the radiant under eyes.

Altogether I will ultimately give this product a hestitant thumbs up, after I got over the learning curve (or maybe just adusted to the pain??) I found this to be a really nice eye cream that did something more than just hydrate my under eyes.

The last product in this line the Targeted Spot Brightener, and also the “cheapest” at only $58 from Sephora also happened to be my favorite in the whole line.


I had never heard of a spot brightener before and after the serum turned out to be a flop for me I was a little scared that this would also not end well, but was pleasntly suprised at the results. After using this over the course of a month I saw that many of my dark spots had faded much more than they typically would’ve even with my normal routine. My PIH tends to stick around much longer than a month or two so seeing the quick fading was really impressive, so I while it costs a pretty penny I really would reccommend this spot treatment.

All in all the Peter Thomas Roth Potent C Collection had a miss, a maybe and one hit for me, but I am a fan of the brand in general (love their Water Drench Moisturizer <3) so while this line might not have been for me I still can’t wait to see what else they come out with next!
