As the oil and the dead skin cells build up, they put pressure on the cells surrounding the pore. With enough pressure, the sides of the pore rupture and the contents of the pore leak into the surrounding skin. Because this sebaceous material contains a lot of P. acnes bacteria, the surrounding skin now becomes infected, creating a red bump that we know as a pimple. The medical term for this red bump is an inflammatory papule.
This next drawing shows an inflammatory pustule, which is different from a pimple only in that it contains white blood cells. When the immune system fights off the P. acnes infection, white blood cells, which are soldiers of the immune system — pile up, creating pus in the pore.
Now another, deeper inflamed lesion can form called a nodule or cyst. It is a solid dome-shaped lesion that extends below the surface, deep into the layers of the skin. Scarring is common with nodules and can sometimes leave an impaction behind, which can flare again and again. When a group of pustules cluster together under the skin, they form a cyst. An acne cyst can appear similar to a nodule, but is pus-filled, and can have a diameter of 5mm or more across. They are usually very painful and scarring is common with cysts.
So you see, acne is primarily an inherited dead skin cell problem. Most acne, no matter what form it takes, starts with microcomedones. This means the solution lies in products that penetrate the pore and prevent dead skin cells from building up. That’s why your home care routine is so crucial — it’s all about preventing the microcomedones (the beginning of acne) from forming at all. This is the best way to get rid of acne.
