Detailed answer

When you rinse your face with hot water, the heat can cause your blood vessels to dilate, which in turn can temporarily enlarge your pores. This can make your pores appear larger. Additionally, hot water can strip away natural oils from your skin, leading to dryness, which can also make pores more noticeable. However, the effect is temporary and will usually return to normal once your skin cools down. For long-term pore reduction, it is important to maintain a consistent skincare routine including gentle cleansing, exfoliation, and using products containing ingredients like salicylic acid or retinol that can help minimize the appearance of pores.
