Is it normal to have one breast softer than the other and a different size, 3 weeks after Breast Augmentation? (photos)

You can expect to have
continued 'dropping' of the implant for up to one year. After that,
gravity and tissue stretch will continue to 'soften up' the appearance of your
upper breast and give you a more natural appearance.

To clarify, implants
don't actually 'drop' (at least they shouldn't) after surgery. What
actually happens is that the chest muscle and breast skin in the upper breast
continue to stretch and relax giving the appearance that the upper part of the
breast is getting flatter (and thus the implant appears to have 'dropped'). In
reality, the implant stays in the same position and the relaxed muscle and skin
allows the implant appearance in the upper breast to go from a bulging look to
a more natural appearance.

Thank you for your question. Congrats on the surgery. It may take months for the breasts to soften and settle, and they may never soften to the pre-surgical state. In addition, the greater the implant to breast tissue ratio, the more the implant will affect the longterm firmness (or softness) of the breast. It is also normal for one breast to soften before the other.  I would exercise patience and see how things change with every few weeks that pass by.

Hi. Your breasts will change for at least 3 months after the operation
(sometimes up to 12 months), and your implants are likely to down a little over
this time and your breasts change shape. It is normal for one breast to go a little faster than the other in terms of settling down after the operation. Try to be patient at this stage and
wait until all the postoperative changes have finished before assessing things

Yes, this is very common after only 3 weeks following surgery.  It is too soon to
see the final results of your surgery as you can have residual swelling for up to 6 months.  It is not uncommon for one side of the body to heal at a different rate than the other.  You must be patient.  Be sure to follow your surgeon’s post-operative instructions and should
you have any concerns contact or visit your surgeon’s office.

Hello! Yes, is it "normal" to have asymmetry of breasts after surgery. Sometimes this can last for up to a year for them to settle and start looking the same. I always tell my patients that your breasts are "sisters, not twins" for this reason! Give it time, be patient, and it should start to even out. 

some asymmetry like what you are descrbing is still normal at 3 weeks.  The smaller breast (larger implant) will need more time to catch up to the larger size (smaller implant).  Try and be patient

At 3 weeks post-op, it is really too soon to worry about your results.  It is normal to experience some asymmetry as you are recovering due to swelling, and it can take 3-6 months for it to resolve.  Try to be patient but do keep an eye on it and do let your surgeon know your concerns.  ac

There are many factors that can potentially cause the difference in feel.
some of them are completely normal, others could potentially be a minor
problem. The normal things are swelling, which is not always symmetric, a
tighter muscle on that side, or the use of different size saline implants. I
understand that your left implant has a larger volume than your right, but the
feel also depends on what size implant that volume was placed into. Your left
could be a 420 implant filled with 420 saline, which would be soft. Your left
could be a 350 implant filled with 380 saline, which would make it feel more
firm.
You could also have a seroma (collection of fluid) around the right
implant, making it feel more firm as well as looking slightly larger.
There are several potential causes. The best thing to do is speak with and
be evaluated by your Plastic Surgeon.

Something is not right but over the internet very very hard to determine exactly the issues!!! Best to seek second opinions in person... 

3 weeks post-op is much too early to make any judgments about your breast augmentation result. One breast may have swelled more as a response to surgery. Or there could have been a little more bleeding on one side than the other. The tissues on both sides need to stretch a little to accomodate the implants. In other words, things are still evolving. Try to be patient, and follow your surgeon's instructions.
