Cleanse & Tone: Acne Skin

the trapped sebum and bacteria stay below the skin surface, a whitehead is formed. Whiteheads may show up as tiny white spots, or they may be so small that they are invisible to the naked eye. A blackhead occurs when the trapped sebum and bacteria partially open to the surface and turn black due to melanin, the skin's pigment. It is not dirt and can not be washed away. Blackheads can last for a long time because the contents very slowly drain to the surface. A blackhead or whitehead can release its contents to the surface and heal. Or, the follicle wall can rupture and inflammatory acne can ensue (see below). This rupture can be caused by random occurrence or by picking or touching the skin. This is why it is important to leave acne prone skin relatively untouched. Inflammatory acne A papule occurs when there is a break in the follicular wall. White blood cells rush in and the pore becomes inflamed. A pustule forms several days later when white blood cells make their way to the surface of the skin. This is what people usually refer to as a "zit" or a "pimple". An inflamed lesion can sometimes completely collapse or explode, severely inflaming the surrounding skin, and sometimes engulfing neighboring follicles. These lesions are called nodules or cysts: When a follicle breaks along the bottom, total collapse can occur, causing a large, inflamed bump that can be sore to the touch. Sometimes a severe inflammatory reaction can result in very large pus filled lesions. Milia are tiny white bumps that occur when normally sloughed skin cells get trapped in small pockets on the surface of the skin. They are common in newborns across the nose and upper cheeks and can also be seen on adult skin. The bumps disappear as the surface is worn away and the dead skin is sloughed. In newborns, the bumps usually disappear within the first few weeks of life. However, for adults milia may persist indefinitely. Treatment is usually not indicated in children. Adults can have them removed by a physician for cosmetic improvement.
