Are my implants too small for it to be 415 cc? Do all implants brand measure the same size implants or are they different?

At three weeks you will still drop and fluff. As the shape improves, you may find quality rules over quantity. You need to allow your breasts to heal, and your skin/muscle to stretch before revision. The volume of your implant is sitting high, because they have not had a chance to settle. When is is time to revise, if 415 is too small 440 will also be too small. Be sure to follow-up with your plastic surgeon.

Hello and thank you for your question. Honestly, a formal in-person evaluation would be needed to determine the best treatment. There are several reasons for this:
1) Bra sizes vary based on the clothing store (for example, Victoria's Secret tends to upsize everyone by a whole cup size)
2) Most women do not wear the proper exact fitting bra size for their bodies
3) The exact volume (in cc) needed to change cup size is different for different body types (e.g. 32A to 32D requires a different implant size than 38A to 38D)
4) Be careful NOT to fall into the trap most women do- they see a certain implant size (e.g. 285 cc) or perhaps their friend had a certain size, and they want or request this or another size based on that. Everyone's body is different- 285 cc implants on your friend might look VERY different than they would on you. Be very careful not to make this mistake, because the goal is to find the right size and shape for YOU- for your particular body and your breasts.

Because of those multiple factors, and because it is KEY to fully evaluate your breasts in person to make a full set of precise measurements to select the proper implant for you (incorporating factors like amount of breast tissue, implant type, base width, projection, etc), answering your question really would need a formal personalized consultation- to say anything before that would simply be guessing, which would be both unfair and unhelpful to you. Also, just FYI, each surgeon's measurements are slightly different, so numbers, experience, and overall aesthetic from one surgeon aren't necessarily the same as those from another surgeon!

Your breasts are such a KEY area of your body and your femininity- therefore, you should ONLY trust an experienced aesthetic plastic surgeon. As such an expert, I have had extensive training and experience with complex aesthetic surgeries under a multiple world-renowned experts in the field. I’d recommend for you to setup a formal consultation with me (or another plastic surgeon who is extremely comfortable with aesthetic plastic surgery procedures) for a formal consultation to thoroughly discuss your surgical goals, undergo a formal examination, evaluate all your options (surgical and nonsurgical), and decide on the best procedure(s) and type of anesthesia for your specific case. I hope this helps!

It is still far too early to determine how the implants will look on you. It takes 3-6 months for breast implants to truly settle into place. During that time, your implants will drop a bit and your skin will stretch to accommodate the larger volume in your breasts. After all of this happens, it is not uncommon for women to say that they feel their implants fit them a bit better. However, if after six months or so you are still unhappy with your size, a simple implant exchange is a very short and easy follow up surgery.
