Why are my pores so big?

The pores on my chest are really big and I don%26#039;t know why. They%26#039;ve been like this for years now and it embarrasses me when I wear my bikini top. My husband doesn%26#039;t like the way it looks either and my mom always use to think there was something wrong with me when I was a teen. Why are they so big and what can I do to make my pores smaller? Thanks in advance for your help :)|||Try using firming cream.
