Peter Thomas Roth Potent-C Power Serum vs Dermalogica Age Smart BioLumin-C Serum

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

The Dermalogica Age Smart BioLumin-C Serum, on the other hand, is not worth its $148 price tag and should be avoided by most people. We strongly suggest that you take a look at some better alternatives if you're considering spending around $170 on a Facial Serum.

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.

As for the Dermalogica Age Smart BioLumin-C Serum - it wasn't considered to be a good enough purchase to earn a spot in any roundups conducted by sources that perform objective hands-on testing, which typically indicates that a product isn't worth its asking price.

As a last step, we wanted to do a head-to-head Peter Thomas Roth Potent-C Power Serum vs. Dermalogica Age Smart BioLumin-C Serum comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
