is there anyway I can make my nose flatter without surgery? (photo)

Although your photo offers limited information, I don't believe that you need to have a flatter nose.  You actually have what appears to be the perfect amount of projection.  At 14, your nose is still changing and will likely continue to change until your later teen years.  Post further photos from the front and side, and I will be able to offer you more advice.  Best wishes!

Despite a wide variety of products and "exercises" that are advertised to reduce the size of your nose, these products and exercises will not reduce the side of your nose, and may even damage your nose.If you are underage, you need to confer with your parents before altering your appearance. In general, by sixteen years of age your nose should be done growing. Non surgical procedures such as fillers like Radiesse are very helpful to improve the shape and contour of your nose. You may be able to fill the radix of the nose and improve the apperance of your nose bridge. The downside to this is that it may make your nose appear longer. A consultation with a plastic surgeon is necessary before making any definitive recommendations.
