Bio oil is a personal favorite of mine and I often use it to supplement my daily body lotion and moisturizer. It manages to make skin look and feel supple with the added bonus of a great fragrance. The 200 ml bottle lasts a couple of months so it is cost effective. My only problem is that it takes time for scars and stretch marks to disappear. It's a bit frustrating because one often gets tempted to think that the product doesn't work. Otherwise, with a little bit of patience spanning over a couple of months, scars and stretch marks will gradually fade.
