A blackhead (technically known as an open comedo) is a yellowish or blackish bump or plug on the skin. An open comedo or blackhead is a type of acne vulgaris. It is caused by excess oils that have accumulated in the sebaceous gland's duct. Blackheads are typically caused by excessive oil and makeup. While the contents inside may look dark, it is not dirt; the substance found in these bumps mostly consists of keratin and modified sebum (an oily secretion of the sebaceous gland) [1]

Possible factors that cause blackheads include :

* Excess dead cells blocking the opening to the pore
* Excess production of facial oil
* Improper cleansing routine, facial oil not being removed
* Excess scrubbing of the skin (Scrubs)
* Use of products/makeup (foundations, sunscreens, and moisturizers) that may contain too much oil
* Use of low quality facial cleansing products


pimples
Tiny pores are connected to oil glands under the skin. These glands produce an oily substance called sebum. The pores connect to the glands by a canal called a hair follicle. Inside the follicles, oil carries dead skin cells to the surface of the skin. A hair will grow through the follicle and out to the skin. When a follicle clogs up, a pimple will begin to grow. This condition is referred to as keratosis pilaris.
