I bought some mederma for my acne scars. I have mostly old scars, but just a few are new.
I need to know 1. how long it will take for them to go away, 2. Does it work great, 3. Will it help clear my ecxzema, 4. What are good times to use it (like at night, morning, times like that), 5. How many times a day should I use it
