Can Insulin help with skin aging?

The claim that insulin can help with skin aging lacks robust scientific evidence. Insulin is a hormone primarily involved in glucose metabolism. Chronically elevated insulin levels (hyperinsulinemia) are associated with accelerated skin aging through mechanisms like increased inflammation, glycation, and reduced collagen synthesis. While topical insulin has been explored in small studies for wound healing, it is not established as an anti-aging intervention. Systemic insulin use without medical indication poses serious risks, including hypoglycemia and hormonal imbalance. The provided context does not support any benefit of insulin for skin aging. Evidence is therefore rated as unclear/mechanistic. Consumers should rely on proven strategies: sun protection, antioxidants, retinoids, and a balanced diet. Always consult a dermatologist before trying unproven treatments.
