How can help to my legs and old scar by contractubex?

I have old scar on my legs caused by acne and boils. It really affects myself confidence. I'm so desperate to remove it. I'm using olive oil. I simply put olive oil on the affected areas twice a day but it seems that it doesn't work at all. I want to use CONTRACTUBEX and it's too expensive. The cost doesn't matter anyway. Is contractubex effective for old scars on legs?
