Does humidity cause acne?

1 doctor answer1 doctor weighed in
Dr. Bryan McIntosh
Plastic Surgery 19 years experience
Humidity and Acne: Humidity itself shouldn't cause acne. However, humidity couple with sweating and soiling of your skin more than usual certainly could worsen acne if you are already acne-prone. Cleansing with an appropriate agent that will avoid over-cleansing and stripping your skin of the correct amount of oils is important to do twice daily.
