one day when i had gone to my cousins place she told that there were blackheads near my nose area.this was a surprising development as i am very concious of my skin and i dont know that how come i have developed these blackheads all of a sudden out of nowhere.i want to get rid of these blackheads as they look really ugly on me and are also a cause of dust and grime that setles on my skin.then my sister told me that i should be using a Blackhead Remover .what is the function of a Blackhead Remover and how much does a Blackhead Remover cost?
