Sientra breast implants are the only FDA-approved 5th generation round implants on the market. These implants are HSC or High-Strength Cohesive silicone gel implants that come in a variety of profiles. This means the silicone gel is designed to hold shape and resist gel fracture while maintaining its softness. The textured shell design of the Sientra implant has been proven to have lower rates of capsular contracture. Capsular contracture is a complication that can occur after breast augmentation, causing tightening/hardening of the scar tissue around the implant. With low rates of capsular contracture, zero reported incidence of implant rotation, and the appearance of soft, natural looking implants with HSC design, it’s no wonder Sientra implants are top rated.
