The hair (or sebaceous) follicle is the target organ in both oil acne (or folliculitis) and chloracne, although the two should not be confused.

The importance of detecting such minor occupational cases is the possibility of systemic toxicity from chloracnegens (causative agents). At present, evidence suggests that the external dose of a chloracnegen required to cause chloracne is significantly lower than that needed to cause systemic disorders (changes in circulating blood lipid levels, porphyria or any form of neoplasia/tumour).
