👉 Allows pimples, also known as whiteheads or closed comedones, occur when hair follicles become clogged with dead skin cells and sebum (oil) from the skin. When pores are blocked, the trapped material forms a small, closed plug at the follicle's opening, creating a whitehead. If the plug becomes open and bacteria enter, it can lead to an infection and transform into a red, inflamed pimple. This blockage typically happens in areas with dense hair growth, such as the T-zone (forehead, nose, and chin), making these areas more prone to developing allows pimples.
