Acne is a genetic condition characterized by an overproduction of sebum and the accelerated shedding of dead cells, in quantities greater than the pore can handle. This exaggerated activity within the follicle causes a bacteria-filled plug to form, clogging the pore. This leads to infected whiteheads that develop deep in the dermis. These can manifest as milder, non-inflammatory acne, such as typical blackheads or whiteheads, to the more inflammatory stage of pink, inflamed, and painful bumps that can be tender to the touch. Large, painful, and solid pustules and nodules or internal boils may also appear. These may require a more comprehensive protocol to treat this type of advanced acne.
