Short answer: Why take the risk? If any bacteria make their way into ANY microscopic spot in either incision that is not completely durable, waterproof, and bacteria-resistant, there is a chance your implant(s) could become infected. Since implants do not have their own natural antibodies, blood flow, and resistance to bacterial contamination, infected implants are not easily treated with antibiotics, and implant removal is the proper way to treat implant infection. Then, after healing is complete, and your scarring has settled, perhaps your surgeon can re-insert your implant(s). Weeks to months later. Who gets to pay for that? And, who has to endure the hassle? One implant in, and the other out? Is it really worth it???So, you can see that with the variation of answers here, my colleagues have either never seen a breast augmentation infection after spa or hot tub or lake, stream, or ocean exposure . . . or they have experienced one, and never hope to have to again.I have personally never had an elective first-time breast augmentation patient develop an infection in the 28 years I have been in private practice, but I've taken care of a couple from other doctors who have treated their patients with antibiotics, stronger antibiotics, Infectious Disease consultations, Home IV antibiotics via indwelling catheter, and everything short of the effective and appropriate treatment--implant removal.So I understand reluctance to allow spa use too soon, and frankly, at two weeks, your incisions may not be durable enough for pressure jets and the softening that occurs with even a few minutes of immersion (who takes a 5-minute spa bath?).If your healing if perfect, and that means no drainage, scabs, crusts, or any sign of "not yet sealed" incisions, I still recommend at least three weeks waiting. 6 weeks may be overkill, but I truly get that recommendation. So ask your surgeon, follow that recommendation, and don't "push it!" Best wishes! Dr. Tholen
