Exercise-induced hormonal acne may worsen as sweat and oil glands are activated with exercise. This leads to clogged pores and the growth of pimples, especially on the skin, if gym equipment and tight clothing are used, which puts pressure on the skin.
Intensive exercise frequently can also be the cause of hormonal stress like cortisol, which may add stress and develop acne. One should not dismiss the importance of maintaining proper hygiene after their workouts to reduce hormonal acne.
