You can use foundation make-up that matches your skin tone to make the scar less visible.How can i get rid of old scars or at least make them les visible?
Buy some bio oil, its for old and new scars.


I had an operation across my throat in February and have a scar that is about 3 inches, I've used bio oil since my op and my scar is hardly visible.


I've spoken to others who've used it and they say it worked for them too.
