What effect does aging have on sebaceous glands?

Aging has a notable impact on sebaceous glands, primarily leading to a decrease in sebum production. As individuals age, the activity of sebaceous glands diminishes, which results in lower levels of sebum being produced. Sebum plays a critical role in maintaining skin hydration, providing a barrier against environmental irritants, and contributing to overall skin health.

As the production of sebum declines, this can lead to drier skin and increased signs of aging, such as wrinkles and fine lines. Additionally, reduced sebum levels can compromise the skin's lipid barrier, making it more susceptible to irritation and dryness. This phenomenon is particularly observed in post-menopausal women, where hormonal changes further exacerbate the decrease in sebum production.

Understanding this decrease in sebum production is crucial for developing appropriate skincare routines and treatments, especially for aging individuals who may need products that replenish moisture and support the skin’s barrier function.
