Will I notice a difference if I go down 100 cc and swap from high to moderate profile? (photos)

Dear Modest,
Changing the profile and volume of your breast implants is certainly an option. You've got a great result already and it looks like you have nice, youthful skin that will contract down to a smaller volume breast. The numbers you mention are reasonable. Good luck!

Based on the information you provided reducing your implants by 100 cc, seems appropriate. Lower profile implants will look more natural and maintain the correct diameter to match the current implant pocket. Reducing the implants by 1/3 will reduce the augmentation by 1/3 total volume change from implants.
There is no correct yes or no answer to your question. In the end, it depends on what you’re trying to achieve.
Personally, I make implant decisions based on the patients reviewing lots and lots of before and after pictures, so I have a clear understanding of what the patient is trying to achieve. I use sizers during surgery and have a large supply of implants available to choose from.This method of choosing implants has worked well for me in the past.
I put a significant amount of effort into discussing outcomes and review this over as many visits as it’s necessary for patients and provider to have a clear understanding of what is hoped for in regards to outcomes.
Working with before, and after pictures of previous patient, who had very similar body types has been the most consistent and accurate way of choosing implants in my experience.
Each provider has their own method of helping patients choose the right, implant, shape and size.
Find the right plastic surgeon, and everything should fall into place.
Best,
