👉 Arise pimples, also known as cystic acne, occur when hair follicles become clogged with dead skin cells, oil, and bacteria. This blockage leads to inflammation and the formation of painful, swollen cysts beneath the skin's surface. When these cysts burst, they release pus and bacteria, causing red, swollen lumps that can become infected. Factors such as hormonal changes, genetics, and poor skincare practices can exacerbate the condition, making it more likely for pimples to arise and persist.
