Should I be worried about visible incision and puckering 3 days post 415cc hp silicone round under muscle? (Photos)

You are still very early in the healing process.  The implants appear to be in good position.  The puckering and breast shape will most certainly improve with time.  Talk to your plastic surgeon about how to make the scars look their best.

Dear amyslp3,I understand that you are worried. However, you are still in the early phase of the recovery period. Please do allow some time for the healing process to occur. Make sure to discuss this issues with your plastic surgeon.Daniel Barrett, MD, MHA, MS

Thank you for sharing your question and photographs.  I see your areas of concern but with the swelling that accompanies surgery it can be difficult to know what your long term results will be as it will maintain your implants in an elevated and flattened position.  As the swelling resolves you should see a more natural breast shape develop with improved fullness along the bottom portion of your breast.  Hang in there and allow your results more time to mature. 

It is too early to tell, and I would give it a few months to heal. Best of luck with your results.....

Thank you for your question. Your breasts will continue to change in the coming few weeks. Your implants drop and swelling comes down. Incision will look fine and puckering get better. Please follow instructions from your PS

Hello The postoperative process of breast implants is delicate. It is important to wait for the period of time necessary for a good recovery, then if you can insert your pearcing. It is good that you make an appointment and consult with a certified and experienced plastic surgeon to suggest the best indications.

Always to serve you I wish you good luck !

FIRST AND FOREMOST, DISCUSS YOUR CONCERNS WITH YOUR DOCTOR.  
I do see some redness in the incision.  My advice would be to get an appointment to make sure you don't have an infection.  Puckering and unevenness can improve with time.  You may not need any further treatment if you allow things to settle, but in the mean time I would recommend that you go to see your surgeon regarding the redness in the incision. I hope this helps.

Your breast contour and projections look good. It is too early to assess how hour incision under your would look like after completion of healing. Keep an eye on it and please send a follow up photo then.
