What is a dilated 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 skin cells accumulate at the pore's entrance, the pore mechanically widens to allow secretions to pass through. This is the phenomenon of pore dilation.
A common myth needs to be debunked: pores do not open and close due to heat or cold. Their size is primarily genetic and conditioned by sebaceous activity. However, their appearance can be significantly reduced with an appropriate routine.
The main causes of dilated pores
Several factors explain pore dilation. Excess sebum is the primary culprit: combination to oily skin types produce more sebum, which mechanically dilates the pores. The accumulation of dead skin cells is the second factor: without regular exfoliation, dead skin cells obstruct and stretch the pores. Age also plays a role, as over time, the skin loses elasticity and pores appear larger. Finally, hormonal fluctuations amplify sebaceous production, particularly during the premenstrual period or puberty.
Active ingredients that visibly reduce dilated pores
Certain cosmetic active ingredients have demonstrated their effectiveness in reducing the appearance of pores. Exfoliating active ingredients like fermented white willow accelerate cell renewal and prevent pore obstruction by dead skin cells. Sebum-regulating active ingredients like zinc, niacinamide, or mattifying plant extracts reduce sebaceous production and visibly tighten pores. Purifying active ingredients like lactoferrin and probiotic extracts maintain a balanced skin microbiome, reducing inflammation that dilates pores.
Routine for dilated pores: the daily approach
In the morning, start with a gentle gel cleanser to remove overnight impurities without drying out the skin. In the evening, after cleansing, apply a targeted treatment containing purifying and regulating active ingredients. Once or twice a week, gentle exfoliation helps deeply unclog pores. At Zactigis, SkinNet and SkinMat products are specially formulated to address pore dilation: the first deeply purifies, the second regulates shine and visibly refines skin texture.
What to absolutely avoid
Certain actions worsen pore dilation. 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 skin's natural balance to allow its regulatory mechanisms to function effectively.
