- Cosmetics - Prolonged use of cosmetics is known to induce acne. Petrolatum, lanolin, vege box oils, butyl stearate, lauryl alcohol, oleic acid are few substances in the cosmetics which trigger acne lesions. Numerous skin lightening creams which contain steroids cause acne. Also pomades, greasy preparations used in hair treatment also cause acnes.
- Occupation - Oil acne, tar acne, chloracne, acne mechanica are few occupational acnes. Those working in the industries exposed to compounds like coal tar derivatives, chlorinated hydrocarbons, cutting oil are prone to develop acne.
- Sunlight - Sunlight (Ultraviolet radiations and ionizing radiations) leads to acne. This type of acne is called acne aestivalis. Also acne seems to be more common in hot and humid environment.
- Drugs and medications - There are numerous medications which lead to acne lesions. Few common ones are oral and topical corticosteroids, anticonvulsants, anti depressants like Sertraline, lithium, anti malarials like quinine, vitamin B12, anti tubercular medications etc.
