There is a common misperception that teenagers are the only population that experience acne.  Because of this misperception many of us think that once the teenage years have passed we should be acne free.  But, the fact is that acne can occur in adults as well.  For many, it is a chronic condition that refuses to go away after their teenage years.

Gender can have an affect on acne, especially in adulthood.  Women are more prone to acne during adulthood than men. The primary reason for this is that women have hormonal changes occuring more frequently (menstration) than men and because women have extreme intermittant hormonal changes related to pregnancy and menopause.  Any factors that contribute to hormonal changes can lead to acne formation.

Finally, the type of skin you have is related to how and why you get acne as well.  If you have naturally (genetically) oily skin, you may be more susceptible to acne breakouts.
