#190) Chemists Test 7 CE Ferulic Dupes vs. the Original
PLEASE NOTE: In this episode, the original Skinceuticals CE Ferulic formula with only 15% ascorbic acid, 1% tocopherol, and 0.5% ferulic acid was tested for this episode. We dive into part two of our vitamin C series by putting popular C E Ferulic dupes to the test. Before revealing our side-by-side stability results, we go through a very helpful study from Slovenia examining 41 finished vitamin C products using HPLC testing to compare the quirks of various vitamin C derivatives—including L-ascorbic acid, ascorbyl glucoside, sodium ascorbyl phosphate, and 3-O-ethyl ascorbic acid. Then we go through our 8 week test findings of 7 CE Ferulic dupes and compare them to the mother formula from Skinceuticals.

#189) Is the updated CE Ferulic worth the $$$$?
We dive into a science-heavy breakdown of vitamin C formulations, focusing on the recent updates to the gold-standard C E Ferulic serum. We explore the history of L-ascorbic acid efficacy studies dating back to the 1990s by Dr. Pinnell’s lab, highlighting the classic UV-induced erythema protocol used to validate antioxidant skin protection. Then, we analyze emerging clinical data around new CE Ferulic additions: carnosine and dandelion endophytol and discuss the available data to see if the chemists can figure out whether or not this is worth the Skinceuticals price tag. 00:00 | Intro! 03:15 | L-Ascorbic Acid: A Brief Review 12:48 | What is Dandelion Endophytol? 25:00 | Carnosine's Clinical UV MED Study 29:30 | Reviewing Carnosine's Clinical Testing 34:15 | The Challenges of Plant Extracts and Actives 38:30 | Chemists discuss CE Ferulic vs. CE Ferulic 2.0 41:45 | The Chemists' Feelings on Patents

#187) Decoding Dr. Reju-All's PDRN & Copper Peptide #ad
#sponsored We’re taking a deep dive into the science behind K-Beauty brand Dr. Reju-All! In this sponsored episode, we've partnered with Dr. Reju-All, to share some of their testing behind the products: the Advanced PDRN Rejuvenating Cream and their latest launch, the Advanced PDRN Copper Peptide Serum. We discuss their PDRN ingredient sourcing and why higher concentrations aren't always better—highlighting in vitro and clinical data showing why 1,200 ppm of salmon-derived PDRN is an optimal sweet spot for barrier recovery and hydration. We also analyze their Advanced PDRN Copper Peptide Serum, exploring how encapsulating delicate copper tripeptides helps maintain formula integrity, alongside its clinical results on heat-induced skin stress, elasticity, and fine lines. Finally, we share our real-world user experience on how to layer these unique gel-gel textures into your existing routine. #rejuall #pdrn #copperpeptide • Dr. Reju-All Official Amazon Store: https://amzn.to/4gfUXI1. • Dr. Reju-All Advanced PDRN Rejuvenating Cream: https://amzn.to/4gdo4LT. • Dr. Reju-All Advanced PDRN Copper Peptide Serum: https://amzn.to/4gAJmo6. #drrejuvall #ad #pdrnserum
