Myths vs facts: Testosteron and Haut

Testosterone affects skin via sebum production and androgen receptors. A common myth is that high testosterone inevitably causes acne. In reality, the effect is individual: testosterone is converted to dihydrotestosterone (DHT), which stimulates sebaceous glands. Acne is multifactorial (bacteria, keratinization, inflammation). Hair loss (androgenetic alopecia) is also often wrongly attributed solely to testosterone – the key is genetic sensitivity of hair follicles to DHT. Another myth: testosterone creams improve skin aging. There is no robust evidence for that; topical testosterone can even cause skin irritation. Facts: Normal testosterone levels are important for skin health, but excess or deficiency do not always manifest on the skin. Direct-to-consumer hormone tests often provide clinically useless results because they ignore diurnal variation and binding proteins. For skin issues, consult a dermatologist or endocrinologist, not a genetic test.
