Retinoids get all the hype and all the confusion. In this episode, we break down exactly what estheticians need to know: the difference between retinoids, retinol, retinal (retinaldehyde), adapalene, and tretinoin, how they work in the skin, and when to reach for each one.

We cover real-world use cases for acne, hyperpigmentation, and aging, how to start clients slow and steady without triggering irritation, SPF non-negotiables, Fitzpatrick considerations, and smart pairing (what to alternate, what to avoid, and how to “sandwich” for sensitive clients). If your clients are hearing TikTok takes and asking you for “the strongest one,” this gives you a clear, professional roadmap without overcomplicating their routines.
