I DO NOT use the gel, I used to but I hated that it peeled when I put on makeup. Now I use the Merderma cream with spf. It is a few dollars extra, but worth it. It goes on easier & I have no problems with it with my make up.
I used Mederma before for about 3 months, & it did help, I'm just can't remember how much it helped because it was a long time ago. But I remember that it did help, I just had to quit using it then because I couldn't afford it! lol.
But now, I'm back on it, have been for a little over a month & I think it has helped. Most of my scars are really old, so I will continue using for some more months (if I can continue to afford it! lol)
But I know for a fact it does help, so I do reccommend it.
