Yes! Making breasts larger and heavier with implants, particularly with more aggressive high or ultra high profile, means they will actually sag or droop faster than without implants. They (your post augmentation results) don't get frozen in time. Larger breasts, particularly with bigger more aggressive implant styles, require 24/7 bra support. This means you need more supportive bras after surgery than before!
Your skin doesn't care whether it's natural tissue, silicone or saline creating the weight, a DD will never hold up as well as a B cup, although you can achieve reasonable longevity with proper care. Accordingly, Dr Feldman and his team, will discuss bra sizing do's and don't's and proper level of support at each and every follow up, as a well fitting, supportive, bra is essential to maintaining your initial results long term. This "pride of ownership" is no different than putting a case on your smartphone or doing maintenance on your vehicle. A well maintained vehicle will always last longer than one driven like a rental. Despite discussing bra support from consult to preop, and continuing with specific instructions at follow up appointments, some of Dr Feldman's patients still don't support their breast properly and then wonder (or complain) why they end up with sagging breasts, lower or more lateral, than they had hoped. An unsupported implant will only maintain its position for 12-18 months at best.
Nothing holds a breast implant in place except your breast tissue, muscle and skin. Unfortunately, not all patients’ tissue has the same strength and therefore, implants can move over time. Woman with more experience in life, or who have had life events like children or significant weight fluctuations, as well as genetic variations are likely to have weaker tissue than their less experienced, nulliparous (without children) counterparts. The larger, and heavier the implant, the more weight the tissue has to support and sometimes it’s just too much and may “bottom out.” Unfortunately there is no threshold size, as one woman’s tissue can support a very large implant and another woman may bottom out with a smaller implant due to the variables described above. Additionally, non-compliance with post-op activity restrictions, lack of supportive bras, stomach or side sleeping and overuse of pectoralis muscle can all move the implant into a less than ideal position.
As such, the most common reason for revision breast surgery at 10 years is going bigger or having a lift. The implant itself didn't change, so there is no warranty, but your breast and body change around it. This is especially true after life events like pregnancy or weight loss/gain, but happens with normal aging and lack of support.
Newer styles like Allergan Natrelle Inspira high fill ratio implants or Inspira Cohesive high fill ratio are designed to keep more volume in upper pole of breasts, where most of Dr Feldman's patients prefer it, without adding projection and more weight like an ultra high profile would, hopefully leading to longer result durability.
Dr Feldman uses Allergan Natrelle implants exclusively. Mentor does not have these newer implant style options, and has 3x higher failure rate, so pay particular attention to the brand, style and profile not just CC's when shopping with competitors. Read more here.
