Noninflammatory acne are usually due to the blackheads and whiteheads.

Blackheads may be due to when a pore is filled by a combination of sebum and dead skin cells and it becomes clogged. The top of the pore is open and always oxidized with the air oxygen that's why looks black so we called these blackheads.

While the whiteheads mouth remains close and clogged with the sebum and dead skin cells.

Histamines are chemicals which body produces in an attempt to defend itself against infection  and to kill the agents from the outside environment. 

                                      

Exceptions: But in some people, the histamines can cause swelling, itching, and many of the symptoms that are experienced with hives. In terms of allergens, hives can be caused by factors which can cause allergy such as pollen, medications, food, animal dander, and insect bites.

 Hives may be due to  stress, tight clothes, exercise, illnesses, or infections. It’s also possible to develop hives as the result of excessive exposure to hot or cold temperatures or from irritation due to excessive sweating.
