My fault I should of looked at the size. Must point out I have paid the same amount for a full size. So so dissatisfied 😩 ### ⭐⭐⭐⭐⭐ Review *by A***R on 15 June 2022* Ich bin mega zufrieden mit dem Produkt ### ⭐⭐⭐⭐⭐ Review *by A***N on 19 April 2026* Wow! Noticeable results overnight! Ive tried everything for around my eyes, as I bought this specifically for my eyes only! I dont do many reviews, but for this I had to. Im in my 60s. After searching results from others with bad eye bags and dark circles on youtube, I tried this and it delivered! Overnight! Noticeable! I couldnt believe my eyes! But, I layered it. First layer Peter Thomas Roth Potent C Power Serum, then PTR Potent C Power Eye Cream, then Numbuzin 9+. A half to 1 pump is plenty for around my eyes only and if anything left over I put on problem areas. For rest of my face Vitamin C, I use Alastin C-Radical Defense Antioxidant Serum and/or Obagi Professional-C 20% serum. Yes, all very pricey. Im happy with this. You think this is small🤣 guess you've never seen other prescribed eye serums, the container is literally as small as my index finger! Im sensitive to any fragrance, but sometimes the ingredients themselves smell. All vitamin C products smell. I didnt think it was bad, its tolerable, no biggie, it doesnt smell any more or less than any other Vitamin C products. It works! Will purchase again. ## Frequently Bought Together - Peter Thomas Roth | Potent-C™ Power Serum - Peter Thomas Roth | Water Drench® Hyaluronic Cloud Cream | Hydrating Moisturizer for Face, Up to 72 Hours of Hydration for More Youthful-Looking Skin, Fragrance Free - Peter Thomas Roth | Water Drench Hyaluronic Glow Serum | Hydrating Serum, Up to 120 Hours of Enhanced Hydration, 1 Fl Oz. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.cy/products/58927816-peter-thomas-roth-potent-c-power-serum-1-fl-oz](https://www.desertcart.com.cy/products/58927816-peter-thomas-roth-potent-c-power-serum-1-fl-oz) --- *Product available on Desertcart Cyprus* *Store origin: CY* *Last updated: 2026-07-07*
