I am looking at the ingredients of silicone sheeting scar gels (expensive!) and did a bit of research on how to bring the price down. Turns out there are silicone-based sex lube gels (cheap!) with the same first ingredient (Dimethicone).
My question: are the scar gels really fundamentally different - or is it all smoke and mirrors to sell it for more money over a pharmacy counter?
In other words: is dimethicone always dimethicone, or can there be structural/functional differences?
Thank you very much!
