Excessive oil on the skin can result in small pustules with a red halo in affected areas.
Commonly, the lesions are seen on the forearms and thighs.
The follicles may obviously be plugged with oil.
The pustules may be sterile or contain the harmless skin bacteria, Staphylococcus epidermidis.
They may be painless or painful.
Topical creams or ointments containing tar can also cause oil folliculitis.
