Detailed answer

Enlarged pores are typically caused by factors such as genetics, age, and excess oil production. Allergies to skincare products, on the other hand, can cause skin irritation, redness, and inflammation. While these allergic reactions may temporarily make pores appear larger due to swelling, they do not actually enlarge the size of pores in the long term. It's important to identify and avoid any skincare products that trigger allergies to maintain the health and appearance of your skin. If you are concerned about enlarged pores, it is recommended to consult with a dermatologist for a proper diagnosis and treatment options.
