Acne is a common skin disease which occurs due to sebaceous gland disorder. It can be a result of hormonal changes, dandruff, junk foods, lack of hygiene, and propionic bacteria. Acne and acne scars are clearly visible in the swollen and red form. The dead skin cells build-up, bacteria, and dried sebum blocks the hair follicles in the skin and results in acne. It can appear in chest, back, upper arms and usually in the face.

There are various stages of acne. First, the Comedones in which blackheads and whiteheads are formed. The second stage is Papules or mild acne in which small and solid bumps are formed. The third stage is Pustules or several acne in which the pimples can burst or collapse. The Fourth stage is Cysts and Nodules which are a result of the burst or collapse of pimples causing skin inflammation. Nodules and Cysts can extend into the deeper skin layers and result in the formation of scars. These are painful and can damage the skin layers. However, there are several methods that dermatologists and cosmeticians offer for this.
