Healing open heart surgery scar

Lauren

Hi ladies.

My baby girl had open heart surgery on the 13 March.

Of course, she has quite a significant scar.

Whats the best oil treatment to lighten the scar?

Cannabis oil, vitamin E etc....???

Update.... Thanks for the advice on scarzone... I'll check it out but doubt my country has it...

Would anyone know of cannabis oil (CBD oil) will work?
