👉 As acne progresses, it typically leads to several types of pimples. Initially, blackheads and whiteheads form as dead skin cells clog pores, creating small bumps on the skin's surface. As these pores become inflamed, they develop into red, painful pimples or pustules, characterized by a white or yellowish center filled with pus. In more severe cases, these inflamed areas can rupture, resulting in deeper, redder nodules or cysts. The combination of bacterial infection, inflammation, and hormonal changes contributes to the formation of these pimples, which can leave lasting scars if not properly treated.
