My 5yo tripped and fell into a corner 8 months ago, splitting her forehead fairly deeply. We took her to the ER and she received 12 stitches. The resulting scar is attached - it is about an inch long and straight. I'm wondering what the best course of action would be - remediate now while she is young or wait until she is older? Would she heal better if we took action now? We have been using Mederma daily and have given her bangs to physically shield the wound from sun. Thank you!
