Myths vs facts: Insulin and Haut

Myths vs facts: Insulin and skin. A common myth is that insulin directly causes skin aging. In reality, chronically elevated insulin (e.g., due to insulin resistance) can increase sebum production via the IGF-1 pathway, potentially worsening acne and promoting skin tags. Another myth: insulin only matters for diabetics. Fact: even non-diabetic hyperinsulinemia (from obesity or prediabetes) can affect skin health, though effects are modest and individual. Evidence is mechanistic and epidemiological, not from large RCTs. Lifestyle changes (diet, exercise) that lower insulin may improve skin. Consumer DNA or hormone tests do not measure insulin directly; a fasting blood test is required. Be cautious of exaggerated claims from 'anti-insulin' diets or supplements.
