As a board-certified cosmetic dermatologist, I'll discuss the benefits and science behind tretinoin and retinol. I explain why these vitamin A derivatives are the gold standard in skincare, debunk common myths, and provide tips on how to incorporate them into your routine safely. I also compare these proven ingredients to alternative products! Drawing from my nearly 20 years of experience and personal use, I share insights on how these ingredients have transformed my patients' skin and my own. #retinol    #tretinoin    #anti aging    #skincare   #skincare products
