How are TSH Schilddrüse and skin aging related?

The thyroid gland, regulated by TSH (thyroid-stimulating hormone), influences metabolism and thereby indirectly affects skin aging. In hypothyroidism (elevated TSH), common skin changes include dryness, roughness, reduced sebum production, and delayed wound healing – all factors that can accelerate skin aging. In hyperthyroidism (low TSH), the skin becomes thin, moist, and prone to redness, which also contributes to premature aging. However, the relationship is complex: TSH alone is not a direct biomarker for skin aging. Other factors like collagen degradation, oxidative stress, and UV exposure play larger roles. Evidence comes from observational studies and clinical experience, not from randomized controlled trials. TSH testing is useful for diagnosing thyroid disorders, but not as an anti-aging marker. To slow skin aging, focus on sun protection, a balanced diet, and adequate sleep – not just TSH levels.
