Introduction
The primary cause of enlarged pores is increased sebaceous gland activity within the hair follicles, resulting in excessive skin oil production. When sebum secretions accumulate within the pores without proper expulsion, they form keratinous plugs that obstruct the pores—leading to rough skin texture and enlarged pores. Additionally, improper skin care—such as over-exfoliation—can irritate the sebaceous glands, triggering excessive sebum production and further contributing to skin roughness and pore enlargement.

Some individuals in daily life experience visibly enlarged skin pores. What causes enlarged pores?

What Causes Enlarged Skin Pores?

The primary cause of pore enlargement is overactive sebaceous glands within hair follicles, leading to excessive sebum production and oily skin. When sebum accumulates and fails to be properly expelled from the pores, it combines with dead skin cells to form keratinized plugs (comedones), obstructing the pores. This results in roughened skin texture and visibly enlarged pores. Additionally, improper skincare—such as excessive exfoliation—can irritate the sebaceous glands, further stimulating excess oil production and contributing to skin roughness and pore enlargement.

Moreover, heightened sebaceous gland activity is often associated with genetic predisposition and puberty. Other factors—including stress, sleep deprivation, and poor dietary habits—may disrupt endocrine balance and impair normal keratinocyte differentiation. Furthermore, aging and unhealthy lifestyle practices—such as smoking and chronic sleep loss—reduce cutaneous blood circulation, depriving skin cells of essential nutrients. Consequently, the skin becomes dry, loses elasticity, and ages prematurely. As the supportive tissue surrounding hair follicles weakens, pores appear larger. In addition, many individuals habitually squeeze or pick at acne lesions, causing epidermal rupture and allowing inflammatory processes from the pilosebaceous unit to extend into the dermis. This leads to dermal damage and the formation of uneven, pitted scars, which further accentuate the appearance of enlarged pores.

Maintain facial cleanliness and hygiene; avoid consuming greasy, spicy, or irritating foods; ensure adequate sleep and prevent constipation. Topical application of Trimcinolone Acetonide Ointment may be considered for localized treatment.
