1.Excess oil production: Some people have more active sebaceous glands, which can produce excess oil, making it easier for pores to become clogged.

2.Hormonal changes: Fluctuations in hormones, especially during puberty, menstruation, or pregnancy, can cause an increase in oil production.

3.Diet: Some foods, such as those high in sugar or dairy, may contribute to acne and clogged pores for certain individuals.

4.Skin care products: Certain cosmetics, moisturizers, or cleansers may be comedogenic (pore-clogging) for some people, leading to clogged pores.

5.Environmental factors: Pollution, sweat, or bacteria can all contribute to pore blockages.
