Mr David Crawford
Silicone and saline have the same shells but the filler is different.
Silicone is gel whereas saline is salt water. With salt water you cannot have shaped implants.
95% patients choose silicone gel as it feels better to touch, wrinkles less and it lasts better over a period of time.
Mr Raj Ragoowansi
In modern contemporary UK/European aesthetic practice, silicone implants are the preferred choice.
Saline and silicone implants both have an outer silicone shell - they differ in their material 'fill' and consistency.
Saline implants are filled with salt water and silicone implants are filled with silicone gel.
Saline implants are rarely used in the aesthetic arena except for the purpose of reconstruction after cancer and when the breast tissue envelope needs to be expanded in cases of congenital asymmetry (where one breast is grossly different to the other) and/or tuberous breast deformity (birth defect breast shape/size).
Saline implants feel stiff and also have a tendency to ripple and 'swish' with activity and have shorter durability than silicone implants.
Mr Alan Park
Both types of implants contain a silicone envelope but silicone implants are filled with silicone and the saline type with saline.
Normally patients opt for the silicone versions as they have a softer, natural feel and usually last longer.
Saline implants have more of a water texture which feels less natural and can be prone to leakage.
