How can my areolas get smaller?

Thank you for your question. At 15 years old you will need your parent's consent to undergo Areola Reduction surgery. I would advise waiting until you're 18 to consult with a certified plastic surgery regarding this procedure. Best of luck to you. 

You are too young to be considering areolar reduction.  Your breasts may still be growing and this may cause further enlargement of your areola.    You have to consider the size of your breast and areola.  If you have larger breasts and if they interfere with activity then you may consider breast reduction when you are done growing as this will also reduce the size.  I recommend seeking out a board certified plastic surgeon when you turn 18.  Be patient. 

As a 15 year old minor, you will require your parents consent to undergo areola reduction surgery. If you would want to undergo surgery, you will have to let your parents know how you feel about your situation. Thanks for your question. Best wishes.
