500cc HP round silicone implants on 5’3 130 female. Advice?

Thank you for the question. The upsizing of breast implants you are considering will make a noticeable difference; the most important question is whether it will achieve the outcome you are looking for. This question cannot be answered online.


Keep in mind as you are thinking about your goals that sometimes adjustment of the breast implant pockets (capsule adjustments) may be necessary to achieve the outcome you are looking for.  
Generally speaking, the best online advice I can give to ladies who are considering revisionary breast augmentation surgery is:


1. Concentrate on choosing your plastic surgeon carefully. Concentrate on appropriate training, certification, and the ability of the plastic surgeon to achieve the results you are looking for. Ask to see lots of examples of his/her work.


2. Have a full discussion and communication regarding your desired goals with your plastic surgeon. This communication will be critical in determining breast implant size/type/profile will most likely help achieve your goals. 
In my practice, the use of photographs of “goal” pictures (and breasts that are too big or too small) is very helpful. I have found that the use of words such as “natural or fake look” or "up a cup size” or "D or DD cup" etc means different things to different people and therefore prove unhelpful.
Also, as you know, cup size varies depending on who makes the bra; therefore, discussing desired cup size may also be inaccurate. 


3. Once you feel you have communicated your goals clearly, allow your chosen plastic surgeon to work with you in determining the best plan to achieve your goals.
I hope this helps. Best wishes. 

As a rough guide, one cup size is about 135 cc's.  This does depend on the width of your breast and the size of your rib cage.  It is very common to go up 100-150 cc with a revision breast augmentation. Typically, revision patients either receive a high profile or ultra high profile implant.  Also, the mentor extra gel implant is a new implant that is so popular it is often on backorder and provides that fake look. My patients have been thrilled with that implant.
