Hi Kate! Cohesive l is the type of gel used in the smooth implants. It is the softest gel mentor implants offer. That’s why smooth are the ‘squishiest’ implants, whilst the textured ones have a harder shell. I had round smooth 275cc moderate + in a dual plane incision.
Visually the smooth implants have less fullness and they tend to drop a bit more (maybe by 1cm) and when you lay down go to the sides more than the textured would. The feel of it though is really good.
The main benefit is that the risk of developing the cancer associated to the textured ones is eliminated, however the risk of implant misplacement and capsular contracture is higher (although this risk is reduced if placed under the muscle or dual plane).
Textured ones however are the most used in North America and Europe.
