Types of acne:
1. Blackheads (open comedo ): A type of comedonal acne that occurs on nose and areas close to it. In this type of acne the blocked pore remains open to the air which causes oxidation and it starts looking black from the top. So, its known as the black head.
2. Whiteheads (closed comedo): Here the pore that has been blocked by oil, bacteria etc closes up and it starts looking white from the top. So, known as white heads or closed comedo. Here the oil gets trapped inside the skin layers and fails to reach the upper layers.
3. Nodules: Nodules are large and firm swellings which exist deep below the skin and does not contain pus. Nodules occur due to accumulation of keratinous remnants and sebum produced from the oil glands within the hair follicile. These leave dark or red marks on skin as they go away.
