My breasts are VERY saggy and pointing down, Is there any way to lift them naturally? (I'm 16 years old).

Thank you for your question. Without photos, it is difficult to comment on options as there are many degrees of sag to the breast.  Unfortunately there are no non-surgical techniques to tighten a breast or the breast skin.  As you are still quite young, surgical options should be postponed until you have finished development.  

You did not include a picture so I have nothing to go on as far as evaluating your situation.  Still, there is no muscle in breast tissue that you can work out to achieve a perkier breast.  I also don't know of any non-surgical procedure that can give you tightening and elevation of your breasts.  I think the bottom line is that, when you are ready, surgery is going to have to be the way to go for you, based on your description.

of course  you would need some  requirements like  your breasts wont be bigger than seize "c" this technique preserve, milking chanels  for  future  baby feeding, besides sensibility for aureolar tissues and  sexuality, this  wonderfull new  technique  avoids  scars staying only at upper areolar zones
