#171) We have to talk about this again: RETINOL VS RETINAL

We are diving back into the "rumor mill" of the retinoid world! Is Retinal actually better than Retinol, or is it just better marketing? In this episode, we revisit the Retinol vs. Retinal debate with new 2026 data. We break down what the evidence says about the retinoid conversion pathway into retinoic acid. We look at the latest clinical evidence to help you decide if it’s time to switch your anti-aging active or stay the course with your current skincare routine.

#170) WE ARE ENDING THIS! Hyperpigmentation Finale!

We are taking a break from hyperpigmentation actives! In this finale, we tie together months of research to help you build the ultimate hyperpigmentation skincare routine. We rank the actives from our last 10 episodes—including Hydroquinone, Azelaic acid, Arbutin, Glutathione, Thiamodol, Symwhite, etc. —from S-Tier (Gold Standard) to Tier “Meh.” We also filter through the 18 products we tested down to the ones we think should be on your radar and warn you about "Niacinamide Overload."
