"Chemists" in the US? That would be the UK, in the US, chemists are not pharmacists but actual chemistry scientists. The International flavor of OCF is fun

For what it's worth, my neck dissection scars have all but disappeared with just massage and regular moisturizer. They used to be quite prominent but are very hard to see now. I had never heard of bio oil so I did a quick Google search and it's a mineral oil based lotion with some herbal oils, vitamins and fragrances added (according to it's web site). It must be popular since it's sold in Walmart and on Amazon etc.. The reviews are mixed, especially for stretch marks, but it seems to fall out on those who liked the feel of mineral oil and those who did not.
