What are five skin care tools that you must have?

Sophia Hernandez is a Registered Dietitian (RD) and health and beauty writer with over 12 years of clinical experience in nutrition, dietetics, and preventive health. She holds a Master of Science in Nutrition and Dietetics from Columbia University Mailman School of Public Health and a Bachelor of Science in Food Science from the University of California, Davis — credentials that place her nutrition writing within one of the most evidence-based and clinically rigorous frameworks in the field. Her content covers clinical nutrition, skin health and diet, weight management, gut health, sports nutrition, eating disorders, beauty from within, and the science behind health and wellness trends that are frequently misrepresented in popular media. Her work has appeared on platforms including Healthline, Everyday Health, and Self, where she contributes medically reviewed articles and nutrition guides for readers who need health and beauty content grounded in verified clinical evidence — not influencer-driven wellness trends. Over 12 years, Sophia has worked with patients across clinical settings including hospitals, outpatient nutrition clinics, and private practice — covering conditions including diabetes, cardiovascular disease, eating disorders, and skin health. She has published 400+ articles and nutrition guides, presented at the Academy of Nutrition and Dietetics (AND) Annual Food and Nutrition Conference, and is a credentialed member of the Academy of Nutrition and Dietetics and the American Society for Nutrition (ASN). Across all her writing, every nutrition claim is supported by peer-reviewed research, every dietary recommendation reflects current clinical guidelines, and no wellness trend is endorsed without evaluating the evidence behind it — because in health content, the gap between what sounds good and what is clinically supported can directly harm readers who act on it.
