Dr. Macrene's Skincare Podcast:Peptides

Episode 6: Peptides

In this episode, Dr. Macrene delves into the world of peptides in skincare, explaining their structure, function, and importance in promoting skin health and longevity. I categorize peptides based on their roles, including dermal regulators, pigment regulators, and neuropeptides, and discusses their clinical benefits, such as reducing fine lines and improving skin elasticity. The episode concludes with practical advice on incorporating peptides into skincare routines for optimal results.

Dr. Alexiades emphasizes the importance of understanding the scientific basis behind peptides, separating fact from marketing hype, and discusses their applications in skin health, including anti-aging and wound healing. She has been formulating with the world's most proven peptides for over two decades, and incorporated the most effective in her High Performance Face Cream, Serum, Eye Cream and Mask, Lip Filler, Neck & Decolletage and Body Cream and Lotion. However, she cautions that while the early data is promising for systemic use, the clinical evidence remains limited and lacks rigorous human trials. Her advice: for now, stick to skincare delivery of peptides.
