Which skin condition is characterized by excessive oil production and clogged pores?

Acne vulgaris is a skin condition characterized by excessive oil production and clogged pores. In this condition, the sebaceous (oil) glands produce a surplus of sebum, which can mix with dead skin cells and block hair follicles. This blockage creates an environment where bacteria can thrive, leading to inflammation and the development of acne lesions such as pimples, blackheads, and cysts. The connection between oil production and pore blockage is a defining feature of acne vulgaris, making it distinctly different from other conditions.

Eczema, psoriasis, and rosacea manifest with different symptoms and triggers. Eczema is primarily associated with inflammation and a compromised skin barrier, rather than oil production. Psoriasis involves rapid skin cell turnover, which leads to scaling and buildup, but is not primarily linked to oil. Rosacea is characterized by redness and visible blood vessels, often triggered by environmental factors, but does not involve excessive oil or clogged pores as a central feature. This differentiation highlights why acne vulgaris is specifically noted for these issues.
