April 09 #172) THEY CLAIM THIS WILL WORK! Reviewing Retinal products!
In this episode, we are diving deep into the retinal (retinaldehyde) landscape to see how current market offerings stack up. Following our technical breakdown of retinol versus retinal, we shift our focus to real-world testing of popular formulations from Krave Beauty, Prequel, Celimax, and Medik8. We examine the scientific validity of concentration ranges—from the entry-level 0.05% to the more intense 0.24%—and discuss how different textures and price points impact the user experience for various skin types. Whether you are a retinoid rookie or a seasoned pro, we provide the detailed assessment on the data to find the right one for your particular skinario.

April 01 #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.
