Evidence check: Nährstoffcheck in the context of skin aging

A nutrient check (e.g., blood test for vitamins, minerals) in the context of skin aging has limited scientific backing. While some nutrients like vitamin C, E, zinc, and selenium are linked to collagen synthesis and antioxidant protection, evidence comes mostly from observational studies or small trials. A comprehensive panel like MyBody-X's can identify deficiencies, but it cannot predict or treat skin aging directly. Skin aging is multifactorial: UV exposure, genetics, lifestyle, and hormones play major roles. Test results are not diagnostic and should not be the sole basis for supplementation. High doses can be harmful (e.g., vitamin A toxicity). Evidence: practice-based, not strongly supported by clinical trials. Consult a dermatologist for skin concerns.
