Peter Thomas Roth Potent-C Power Serum vs Cetaphil Deep Hydration 48 Hour Activation Serum

The Peter Thomas Roth Potent-C Power Serum is a great Facial Serum for its $78 asking price.

The Cetaphil Deep Hydration 48 Hour Activation Serum, however, while a reasonable product for $20, doesn't stack up against its competitors quite as well. If you're considering Facial Serums in the $15 range, you might want to check out some better options.

The reviewers at allure.com have featured the Peter Thomas Roth Potent-C Power Serum in their 19 Ferulic Acid Products in 2023 to Brighten Skin roundup. However, it fell short of making it to the top of their list.

Moving on to the Cetaphil Deep Hydration 48 Hour Activation Serum: no sources that perform reliable and objective hands-on testing have included it in their Facial Serum roundups, which usually means that a product doesn't make for a good purchase.

As a last step, we wanted to do a head-to-head Peter Thomas Roth Potent-C Power Serum vs. Cetaphil Deep Hydration 48 Hour Activation Serum comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
