Enlarged pores can be caused by several factors, including:

1. Genetics : Some people are genetically predisposed to having larger pores.
2. Excess oil production : When the skin produces too much oil, it can lead to clogged pores and make them appear larger.
3. Aging : As we age, the skin loses its elasticity, which can make pores appear larger.
4. Sun damage : Overexposure to the sun's rays can damage the skin and lead to larger-looking pores.
5. Use of comedogenic products : Pores that are blocked with dirt, oil, and dead skin cells can lead to larger-looking pores. Using non-comedogenic products can help prevent this

It's important to note that while there are steps you can take to make your pores look smaller, you can't actually get rid of your pores, and there's nothing wrong with having enlarged pores.
