Can ultra-processed foods accelerate visible skin aging? In this in-depth video, board-certified dermatologist Dr. Dray breaks down the science behind diet, inflammation, glycation, and collagen loss.
In this evidence-based discussion, Dr. Dray covers:
• What ultra-processed foods actually are
• How sugar drives glycation and damages collagen
• Advanced Glycation End Products, also known as AGEs
• The association between ultra-processed food intake and acne, eczema, psoriasis, and hidradenitis suppurativa
• The gut-skin axis and emerging research on emulsifiers and preservatives
• Why topical skincare cannot fully counteract a chronically inflammatory diet
• What we know and what we still do not know from current research
Dr. Dray emphasizes that correlation does not equal causation. Much of the research linking ultra-processed foods to health outcomes is observational. However, the most consistent finding is that these foods tend to be calorie dense, low in volume, and nutrient poor. That metabolic pattern can influence inflammation, insulin signaling, oxidative stress, and ultimately skin biology.
Topics discussed include:
• Glycation and the internal “caramelization” of collagen
• Matrix metalloproteinases and collagen breakdown
• Blood sugar spikes and insulin resistance
• The Maillard reaction and dietary AGE burden
• How chronic inflammation impacts dermal aging
• Why collagen remodeling takes time
Dr. Dray also outlines realistic dietary shifts that support metabolic health and skin resilience, including increasing whole foods, fiber diversity, omega-3 rich foods, and adequate protein intake.
