Is acne vulgaris caused by dirty skin or poor hygiene?

    Last Updated: May 16, 2025

    Acne vulgaris is not caused by dirty skin or poor hygiene because the processes that lead to acne occur beneath the skin. Regular or excessive washing may not improve acne and could potentially worsen skin conditions.

    While many people think that having dirty skin can cause or exacerbate acne symptoms, most of the processes that cause acne actually occur beneath the skin — not on it. For this reason, regular or excessive washing likely has no effect on acne at best and, at worst, may aggravate the skin.[1]
