Hi Siobhan.
I am now 17weeks PO and my stretch marks are hardly vissable anymore.
I had stretch marks before my op due to weight loss and gained a few new ones after my op.
However I started using this cheep bio oil from home bargains (£2) 1 week PO and now my stretch marks are almost non existent and my scars are nearly gone.
Use it 2x day and you should see results like mine in no time.
Hope this helps. Xxx
