Is 125cc downsize going to make me look too small? (Photos)

Thank you for your question and providing photos. Based on your photos and without knowing your dimensions, I do think you will be fine with a smaller implant in addition to a lift procedure. Best of luck

My opinion would be to go closer to 400cc-420cc's since your lift will likely reduce you by at least 1/2 cup size.  Many patient go smaller and regret going too small. You also tend to lose more and more upper fullness with smaller implants.  This is just my two cents, however. 

500
cc implants weigh over 1 lb each and are causing your breasts to descend.  375 cc implants will result in large breasts
and you will need a lift.  I do not
recommend the anchor lift because it results in ugly vertical scars, loss of
nipple sensation and the inability to breast feed.  The alternative I recommend is explantation
using The Bellesoma Method.  The implants
are removed, your breast tissue is reshaped creating upper pole fullness,
elevated higher on the chest wall and more medial to increase your
cleavage.  Vertical scars are avoided,
nipple sensation and the ability to breast feed are maintained, if not injured
during your previous surgery.  At the
same time or later, fat transfers can be performed if additional volume is
desired.  Implants are not lifetime
devices and half are removed by 9.5 years.Best Wishes,Gary Horndeski, M.D.

 I think with the amount of tissues that you have, if you just changed your implants you probably wouldn’t notice much size difference, maybe half a cup. But it also depends on how much tissue they are going to remove when you do the lift. I personally tend to remove more tissue so less will droop in the future. But it depends on how much your doctor thinks they will remove !!!

Dear sammyy24,breast implant type and sizing selection is a complicated process and requires a detailed consultation that includes a discussion of your goals, a detailed examination, and a lengthy discussion. But the decision will always start and end with the patient. When it comes to sizing, we have all of our patients find 3 photos of their desired breast size. We ask for naked breast photos because clothing can obscure the true size (push up bras). Next, we consult with patients and go over the photos and take detailed breast measurements during a physical exam. Next, we using a sizing algorithm to determine a range of implants that will work based on the exam and the measurements.Lastly, during the operation, we use silicone sizers in the operating room to see how the size actually looks in the breast. We sit the patient up in the operating room, while asleep of course, and compare the sizer result with their desired look photos. If it is too small, we start the process over with a slightly larger implant. We don't stop until we get the perfect match.Of all of my breast augmentation patients, every one of them has been happy with their size due to this detailed and meticulous process. You don't want to invest time and money into a result that is either too big or too small.You should discuss your concerns with a board-certified plastic surgeon and make sure that your surgeon understands your goals.Daniel Barrett, MD

From your photos, it appears that a downsize and lift will better fit your body, but there is no way to accurately predict the specific volume. You need to communicate with your surgeon to better determine your goals, and then allow them to choose your size in surgery to best fit your desired outcome. Be sure to find a board certified expert in breast surgery before you proceed.

Given your concerns/goals, you seem to have a reasonable plan. 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.  Much will be dependent on your physical examination;  specifically, factors such as the amount of redundant skin and  quality of skin elasticity will be important.
 The 150 cc you are considering downsizing will likely make a "noticeable difference"; what cannot be determined online is whether it will be the exact difference necessary to achieve an outcome that you will be pleased with.
My best advice: more communication.
It is definitely worth spending more time (prior to the date of surgery) with your plastic surgeon to discuss further.  As you know, it will be important for many reasons, that you feel comfortable that you and your plastic surgeon are on the "same page" prior to proceeding.  Show your plastic surgeon what your goals using as many visual aids as possible.  This additional communication will go a  long way when it comes to helping alleviate your anxiety prior to proceeding.
Generally speaking, the best online advice I can give to ladies who are considering revisionary (downsizing) 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 "down a cup size” or "too small" etc may mean 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.  

A 375 cc implant will create a more subtle appearance and reduce the likelihood of additional lifting down the road. Your current implants are too large for your frame.

Dear Sammyy24,Hello and thank you for your excellent question. Down-sizing your implants will not make you too small, but will certainly require a lift when you are done. It is best to answer your question during a face-to-face evaluation, when you can discuss your goals and expectations for the procedure, and you can have a physical examination to evaluate for that procedure. I recommend that you find a board-certified, or board-eligible plastic surgeon with whom you are comfortable. Be sure to have all of your questions answered during a face-to-face meeting with your surgeon, and review before and after pictures of similar patients whom have had this procedure. If you have any questions, call our office for assistance. Good luck!
