The key possible reasons to why people with similar lifestyle have different acne incidence rates include:
- Genetic predisposition. Acne can run in the family through genetic mutations which would, in turn, cause acne to develop.
- Use or lack of use of acne prevention strategies e.g. topical retinoids. Not having proper hygiene would cause oil-clogged pores and in turn, cause acne to develop on the face.
- Diet. A high glycaemic index diet promotes acne. So does excessive intake of dairy products.
- Use of comedogenic make-up. Comedogenic makeup would cause clogged pores, whiteheads and blackheads to form, causing an acne-prone skin to be more susceptible to breakouts
