What commonly results from hyperactivity of sebaceous glands?

The condition commonly resulting from hyperactivity of sebaceous glands is oily skin. The sebaceous glands produce an oily substance known as sebum, which serves to lubricate and protect the skin. When these glands are overactive, they produce an excess of sebum, leading to a shiny appearance and a generally greasy feel to the skin. This can contribute to other skin concerns such as acne, as the excess oil can block pores and lead to breakouts.

In contrast, dry skin typically results from insufficient sebum production, while skin irritation can occur due to various factors unrelated to gland activity. Sunburn is primarily caused by excessive UV exposure and does not directly relate to the activity of sebaceous glands.
