If you are 40 or older and serious about aging well, understanding how retinoids work is essential. Save your money by choosing the right Retinoid! Are retinoids really the gold standard in anti-aging, or just overhyped? In Episode 1 of The Biology of Aging, Dr. Linda Brand, MD breaks down the full science behind retinoids: • What a retinoid actually is • How retinoic acid signaling works in the nucleus • RAR-alpha, RAR-beta, RAR-gamma explained • Retinol vs Retinal vs Prescription Tretinoin • Retinyl Retinoate (r-Retinoate™) - what makes it different • Irritation myths (does peeling mean it’s working?) • Collagen remodeling timelines (what really happens at 3–6 months) • Layering with peptides, copper peptides, vitamin C & acids • Mature skin strategy vs sensitive skin strategy • How to avoid barrier damage This is not a product review. This is a mechanism-level deep dive. Because prevention is not about hype. It’s about understanding biology. #retinol #retinal #retinyl #retinaldehyde #retinoids #retinoid #tretinoin #aging #antiaging #antiagingskincare -- LINKS -- (When available, I use affilliate links and may earn a small commission). * Visit my shop to see my favorite products: https://shopmy.us/lindabrandbeauty Shop everything mentioned in this video here: https://shopmy.us/collections/4172470 MEDIK8 | R-Retinoate Day & Night Youth Activating CreamMedik8-Exclusive Encapsulated Retinyl Retinoate - Proven to Be 8x More Powerful than Standard Retinol: https://go.shopmy.us/p-45110495 Crystal Retinal: https://go.shopmy.us/p-45110504 PAULA'S CHOICE | Clinical Pro Retinaldehyde Dual-Retinoid Treatment : https://go.shopmy.us/p-45110521 INNBEAUTY PROJECT | Retinol Remix 1% Retinol Treatment: https://go.shopmy.us/p-45110611 Intelligent Retinol™: https://go.shopmy.us/p-45110389 The Ordinary | Granactive Retinoid 2% Emulsion: https://go.shopmy.us/p-45110392 Cosrx | The Retinol Cream, .1 Oz: https://go.shopmy.us/p-45110480 A313 | Vitamin A Pommade: https://go.shopmy.us/p-45110638 Hydrating Treatment Mask: https://go.shopmy.us/p-45110398 Shop more of my favorite products here: https://shopmy.us/lindabrandbeauty Discount Codes: Lumeo (Code: LINDABRAND15): https://go.shopmy.us/p-37603237 BeautyBio (Code: LINDABRAND15): https://go.shopmy.us/p-38114822 Epsom-It (Code: LINDABRAND15): https://go.shopmy.us/p-38114856 * CONTENT CREATOR? - Enable your audience to shop your product recommendations while building meaningful partnerships with world-class brands: https://shopmy.us/join/lindabrandbeauty Disclaimer: This content is based on my personal experience and professional opinion as a medical doctor and skincare enthusiast.
