Scars are sooo different for everyone. For instance, some people get the simplest cut and it's a white scar, for life. Others, get surgery scars and are left with a simple line, or a very thick red line for life. It's soo varied for everyone. Different things also work differently. The fact remains you can choose to use one or many things, and give them all a few weeks to work, and use them properly while also taking care of your skin (avoid lots of sun / harsh cleansers, etc.). If one treatments seems to have hit a brick wall, try something else. Sometimes simple things like Vitamin E and Cocoa Butter work amazing for some. Other times, Mederma or Bio Oil can be better for others. Some crappy cases, none of this works and they are stuck or seek laser treatments.
My aunt who has had multiple surgeries, always uses Vitamin E. Her scars are no longer able to be noticed by touch, but have color differentiation. It's weird! So far it's too early for me to try scar treatment as I'm still healing for another week. But, we'll see. I wish you luck. Patience, persistence, and observation will work best. =)
