The spark that puts them to work. The DRx BioRejuvenation™ Serum is Dr. Dennis Gross's most advanced facial rejuvenation treatment - a first-of-its-kind formula that combines Collagen Amino Acids with G.N.A. (Glutathione, Niacinamide, and Adenosine) to deliver visibly tighter, lifted, and sculpted skin from home. Collagen Amino Acids are the essential building blocks that make up collagen - found naturally in skin - delivered here in a precise ratio that supports the skin's structural proteins directly. G.N.A. acts as the ignition: Glutathione, Niacinamide, and Adenosine are precursors to NAD+ that activate the skin's natural energy cycle, allowing the Collagen Amino Acids to work deeper and more effectively than either complex could achieve alone.\u003c\/p\u003e\n\u003cp\u003eThe result is targeted treatment across the areas that show aging most visibly - nasolabial folds, jawline, jowls, and neck - for all-over facial rejuvenation with long-term resilience built in.\u003c\/p\u003e\n\u003cp\u003eOne daily application.

Twist bottle to open and lock the pump into place. Press the pump's centre to evenly release product. Massage 2-3 pumps into clean, dry skin. Follow with eye cream, then moisturizer.

For optimal results, apply after your Alpha Beta® Daily Peel and before moisturizer, working from thinnest to thickest texture if layering multiple serums.\u003c\/p\u003e\n\u003ch2\u003eWhy MASC Recommends This\u003c\/h2\u003e\n\u003cp\u003eThis anti-aging serum works  at the level of collagen architecture. Delivering the actual amino acid building blocks of collagen alongside NAD+ precursors that power the skin's energy cycle is a fundamentally different approach to rejuvenation - one that targets the structural cause of sagging and lost firmness rather than the cosmetic symptom. The specific focus on nasolabial folds, jawline, jowls, and neck addresses the areas where facial aging is most visible and hardest to treat topically. The eight and twelve-week clinical data across 50 participants each tells a consistent story: this is a serum that delivers measurable structural improvement over time. If anti-aging is a priority in your routine, this is where to invest.\u003c\/p\u003e","brand":"Dr. Dennis Gross","offers":[{"title":"Default Title","offer_id":50578476859631,"sku":"43000375101","price":120.0,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0855\/2590\/files\/1_daeb7b56-8bb8-46de-a337-71eea9c8488a.jpg?v=1787693138","url":"https:\/\/shopmasc.com\/products\/dr-dennis-gross-skincare-drx-biorejuvenation-serum-collagen-amino-acids-g-n-a-30ml","provider":"MASC","version":"1.0","type":"link"}
