Nodular acne is formed when pores breaks and a total collapse occurs, causing large and painful bumps on your skin surface.
Nodular acne grows deep under the skin thus squeezing the pus out would be difficult and you probably would have cause inflammation or even scarring on your skin by squeezing before the pus is squeeze out.
Both nodular and cystic acne can caused permanent scarring easily if not taken
with good care. Lumps form by nodule acne is painful and huge, causing an awful look.
Be prepared to stay with nodular acne for months if you had one as the infection
for nodule is far deeper into than skin than pimple and comedone.
