What is an enlarged pore and why does it appear?

A skin pore is the opening through which sebum produced by the sebaceous gland reaches the skin's surface. When this gland produces excess sebum, or when dead cells accumulate at the pore entrance, it mechanically widens to allow secretions through. This is the phenomenon of enlarged pores.

A widespread myth needs to be addressed: pores do not open and close with heat or cold. Their size is primarily genetic and conditioned by sebaceous activity. However, their appearance can be significantly reduced through an adapted routine.

Main causes of enlarged pores

Several factors explain pore enlargement. Excess sebum is the main culprit: combination to oily skin produces more sebum, which mechanically enlarges pores. Dead cell accumulation is the second factor: without regular exfoliation, dead cells obstruct and stretch pores. Age also plays a role, as skin loses elasticity over time, making pores appear wider. Finally, hormonal fluctuations amplify sebaceous production, particularly in the premenstrual period or during puberty.

Actives that visibly reduce enlarged pores

Several cosmetic actives have demonstrated their effectiveness in reducing pore appearance. Exfoliating actives like fermented white willow accelerate cell renewal and prevent pore obstruction by dead cells. Sebum-regulating actives like zinc, niacinamide or mattifying plant extracts reduce sebaceous production and visually tighten pores. Purifying actives like lactoferrin and probiotic extracts maintain a balanced skin microbiome, reducing the inflammation that widens pores.

Routine for enlarged pores: the daily approach

In the morning, start with a gentle gel cleanser to remove night impurities without drying the skin. In the evening, after cleansing, apply targeted care containing purifying and regulating actives. Once or twice a week, gentle exfoliation helps deep-unclog pores. At Zactigis, SkinNet and SkinMat products are specifically formulated to act on pore dilation: the first deeply purifies, the second regulates shine and visually tightens skin texture.

What to absolutely avoid

Some gestures aggravate pore enlargement. Squeezing blackheads forces the skin to widen further and risks creating inflammation. Using products that are too greasy or comedogenic clogs pores. Washing the face too frequently destroys the natural hydrolipidic film, which paradoxically stimulates compensatory sebum production. The Zactigis approach is based on a simple principle: respect the natural skin balance so its regulation mechanisms can function effectively.
