Hello! It's good that you know about the precipitating factors of acne. The other things to take care of are dandruff,oily skin,hormonal changes and stress. Sometimes weather changes may affect our skin leading to eruptions. You have to also look into the various products that you are applying such as foundation,compact powder,mousse etc. Some oral medications may also precipitate this type of acne. Threading, waxing and other beauty parlour activities are also stressors for it. Definitely consult a dermatologist who can analyze your skin and prescribe you facewash as per your skin type and few medications. This type of acne also responds very well to salycylic peels.
