Acne is one of the most common skin problems that results from blocked pores, excessive oil, bacteria, and inflammation. These skin problems manifest themselves in the form of pimples, blackheads, or cysts on the skin. These are found on the skin of the face, chest, and back. Knowledge of what exactly acne is, what causes it, and what the best treatments for it are will help to manage and prevent it.

What is Acne?

Acne or acne vulgaris is a common skin condition in which hair follicles are filled with oil and dead skin cells, leading to whiteheads, blackheads, and even pimples and deeper bumps. Although acne commonly occurs among teenagers, adults with acne-prone skin may also suffer from acne due to lifestyle and hormonal changes.

  • Pustules: Pimples filled with pus, often red at the base with a white or yellow center.
