Almost all of the consumers claim that it has a positive effect on their skin, there are several comments informing that Mederma Skin Care For Scars works even on scar formations that are years old.

How to apply Mederma Advanced Scar Gel?

As like with any other product for the treatment of scars, Mederma Advanced Scar Gel should never be applied to open wounds or unhealed or fragile skin. It can be only applied to preventing scars from forming on newly healed wounds.

The directions suggest gently massage the product into the scar until there is no shiny, wet, or sticky feeling left. If your skin appears to be dry or is flaking after you apply the gel, you may be using too much.

After applying the product on the affected area, you should let it dry on the skin.
