(HealthDay News) -- Acne can strike people of any age for different reasons, but there are several factors that can worsen or trigger breakouts.

The American Academy of Family Physicians notes these possibilities:

• Using products with an oil base, such as cosmetics, hair products and suntan oil.
• Being under emotional stress.
• Undergoing changes in your hormones, particularly during menstruation.
• Picking at or squeezing pimples on your skin.
• Scrubbing your skin too vigorously.
