Hello @suzieq096, thank you for your question. It may be due to a difference in the integrity of the implants. For example, if one implant has ruptured or leaked, it could change the appearance of the implant fluid, making it look "icky." Saline implants, when ruptured, tend to deflate quickly as the body absorbs the saline. Silicone implants, on the other hand, may not show signs of rupture immediately, as silicone tends to stay within the capsule (scar tissue that naturally forms around the implant). Best wishes!
