Generally, men have more oily skin than women due to their higher testosterone levels. This hormone stimulates the sebaceous glands, which produce sebum, the oily substance that keeps skin moisturized. Men have larger and more active sebaceous glands than women, leading to increased sebum production. As a result, men's skin is typically oilier and shinier than women's.
While women also experience hormonal fluctuations that can affect sebum production, men have consistently higher levels of testosterone, which contributes to their oilier skin.
