I am not at all convinced that any of these products have any effect on scars.
I had surgery at the age of 13. The scar is mild, but still there.
I broke my arm and needed surgery in 2010. The scar is pretty evident, and nothing I have done seems to affect it.
I had another surgery in 2024. I haven’t done anything, but that scar is almost invisible.
My cat scratched me in the 1990s. That scar is more apparent than some of my surgical scars.
I find no evidence that scars can become less visible as a result of treatments.
This is all anecdotal. I have no actual evidence.
In this day and age that probably qualifies you as an expert! You could probably testify before Congress. LOL..
