Pimples or whiteheads (which are the same thing) sometimes occur in clusters. This is normal, and is often related to sweating or friction which both worsen them. This is especially common when pimples occur on the armpits, neck, thighs or other places other than the face. Pimples or whiteheads are a form of
acne. The develop when skin pores become clogged closed by dead skin and other debris, leading to the build up of skin oils, bacteria, and white blood cells. Removing the dead skin debris is the primary treatment for acne. Doing this requires daily use of a good soap. Many people also add an exfoliating preparation, such as one containing microbeads. Benzoyl peroxide or other acne products may also be helpful. As always the diagnosis and the management of your particular condition will require a physical examination by your personal physician. Setting up an office visit with your
primary care doctor or your
dermatologist might be indicated.
