Hey! i was scared of the same thing. For 3 months i used vit E oil and it significantly helped with the scarring. One of my incisions is completely gone. I just ran out of it (i would apply it on twice a day and rub it in well) so i decided to try scarguard and literally in just 2 days of using it i can see a difference. My biggest incision was super dark, hard, and puffy and scarguard already flattened out the cut and lightened it a bit. I dont know if everyone else got this result but im really glad i bought it, granted it cost me 30 bucks (as opposed to the vit e which was only 5) im really hoping it helps in the long run!
