I have 5-6 chicken pox holes from last two years on my forehead, nose and cheeks, in short my face. I feel very depressed because of them. I have tried hexilak gel as suggested by my dermatologist, visit many of them. But these scars are not gone yet. One of my friend suggested me to try" mederma" Will it be effective? And if not please suggest some other stuff. And I am currently applying coconut oil on these scars but not seeing any improvement. Please help! Thank you!
