Hardly anyone will care about this but: in case you are looking to find a better alternative to Mederma for scar treatment, I found one at Whole Foods called Derma E Scar Gel. That is what I am using on E's lip. The reason I did not want to use the Mederma: three of the ingredients are known carcinogens and/or unregulated. Those three are PEG-10, Fragrance, and methylparaben. (According to the EWG website anything with "PEG" in it is bad, parabens in general are bad, and fragrance is bad because it can mean almost anything, you never know.)
Rant: These filler ingredients are dangerous! I get upset when they put them in children products like shampoo, bubble bath, sunscreen, scar gel, toothpaste, hair products, hand wash, etc. We should be able to trust that what we are buying is safe, and we cannot. Lame! I read ALL my labels now.
