Evidence check: Hormoncheck Frauen in the context of skin aging

A hormone check for women in the context of skin aging is often marketed as a personalized anti-aging tool. However, the scientific evidence is weak. While hormones like estrogen, progesterone, and testosterone do influence skin health—via collagen production and moisture retention—most commercial hormone tests (saliva, blood spot) provide only a snapshot and are not validated for predicting skin aging. Hormone levels fluctuate significantly with menstrual cycle, time of day, and lifestyle. Studies show only a modest correlation between single hormone measurements and skin aging. Instead, factors like UV exposure, diet, sleep, and stress dominate. A hormone check can be misleading, leading to unnecessary supplementation or hormone therapies with potential risks. The evidence level is 'marketing': it relies on biological plausibility but lacks robust clinical trials demonstrating benefit for skin aging. Consumers should be cautious and focus on proven anti-aging strategies such as sun protection, a balanced diet, and good sleep hygiene.
