How do I apply the Scar Gel? Do I apply a thin layer?

Yes, just a small drop or two goes a long way.

Please note, the bottle is small but is supposed to be roughly a 3 month supply when used as directed.

Of course, if the scar area is large it may require more material and reduce this supply duration. A thin layer is all that is needed and then allow it to dry before applying any sunscreen or make up to the area.
