Costs for addressing skin aging through nutrition vary widely depending on the approach. A basic antioxidant-rich diet with fruits, vegetables, nuts, and healthy fats is relatively affordable, around 50–100 € per week for one person. Specialized 'anti-aging' supplements such as collagen peptides, coenzyme Q10, resveratrol, or astaxanthin range from 20 to 80 € per month, often without robust clinical evidence for significant skin aging delay. High-priced lab tests (e.g., telomere length measurement, epigenetic clocks, comprehensive micronutrient panels) cost 200–600 € per test but are mostly non-standardized and of unclear predictive value. Dermatological consultations and skin analysis devices (e.g., VISIA) add 50–200 € per session. Importantly, many expensive offerings are based on marketing rather than solid evidence. The most effective and cost-efficient measures remain sun protection, not smoking, a balanced diet, and adequate sleep. Consumers should critically evaluate whether a product or test is actually scientifically supported.
