How are Body-Balance Check | Testosteron-Test and Haut related?

The relationship between the Body-Balance Check (Testosterone Test) and skin lies in hormonal regulation. Testosterone influences sebum production, hair growth, and collagen synthesis. An imbalance—either too high or too low—can affect the skin: acne, oily skin, or reduced elasticity. However, a single test is insufficient to causally link skin issues to testosterone. The evidence is based on physiological mechanisms and observational studies, not RCTs. Other factors like stress, diet, or genetics may play a larger role. The test can provide orientation but does not replace medical diagnosis. Beware of marketing claims that suggest a direct causal link.
