enlarged oil glands causing small, yellowish facial bumps
Sebaceous Gland Hyperplasia is a condition where the sebaceous glands, which are responsible for producing oil (sebum) to lubricate the skin, become enlarged. This often results in small, yellowish bumps on the skin, typically on the face. While generally harmless, it can be mistaken for other skin conditions, and its appearance may be of cosmetic concern.
