How are Progesteron and skin aging related?

The provided context does not contain specific information on the relationship between progesterone and skin aging. In general, progesterone is a steroid hormone that may influence skin structure through collagen synthesis, sebum production, and hydration. During perimenopause, declining progesterone levels are associated with loss of elasticity and wrinkle formation. Topical progesterone is sometimes marketed for anti-aging, but scientific evidence is weak, based on small studies or animal models. No robust human trials confirm that progesterone supplementation significantly delays skin aging. Risks include systemic absorption and hormonal side effects. Without direct context sources, the evidence level is 'unclear'. Consumers should be cautious about DNA tests or hormone products claiming skin rejuvenation; proven strategies include sun protection, a balanced diet, and medically supervised hormone therapy when indicated.
