Allergen Soft Touch or Sientra HSC+ - which implant will give the most upper pole fullness?

Thank you for your question. A large portion of my practice is dedicated to breast revision surgery. I have been in practice for over 30 years. The answer to your question is more about the surgical technique then the implant. When somebody wants more upper pole fullness, I perform an internal bra/capsulorrhaphy procedure with mirror image capsulotomy. I wrote the very first paper on this in 1999. I will also usually use an ultra high-profile implant. I believe Sientra and Allergan make very similar style implants. I prefer Allergan. Without a picture, I cannot make any further comments. Best wishes to you.

I think the type of implant is probably less important than other things. It sounds like your previous lift may need to be tightened up in the lower portion. Also the size of the implant will make a significant difference.

High profile implants give the greatest amount of projection and overinflated saline implant will also give a lot of projection.
There’s no implant that selectively gives greater projection in the upper pole, then the lower pole.
Talk to your plastic surgeon about their recommendations.Best,
