How are Testosteron and Haut related?

The relationship between testosterone and skin is not directly addressed in the provided context. Generally, testosterone stimulates sebum production, which can lead to acne or oily skin when elevated. It also influences hair growth (e.g., androgenetic alopecia) and collagen synthesis. Low testosterone may contribute to dry, thin skin. Evidence is based on clinical observation and endocrinological studies (human-moderate). Caveat: Consumer hormone tests are not diagnostic; single readings fluctuate due to time of day, stress, or diet. For persistent skin issues with suspected hormonal cause, consult a dermatologist or endocrinologist.
