Detailed answer

Excessive sweating does not directly affect the size of pores. Sweat glands and pores are separate structures within the skin. Sweat glands produce sweat, which is then released through pores onto the skin's surface. Pore size is primarily determined by genetics and age. However, when sweat mixes with oil, dirt, and dead skin cells on the skin's surface, it can clog pores and lead to breakouts. Regularly cleansing the skin and using non-comedogenic products can help prevent clogged pores. Additionally, excessive sweating can cause dehydration, which may result in dryness and dullness of the skin. It is important to maintain proper hydration by drinking enough water to keep the skin healthy and moisturized.
