I have given this product 5 stars as it is truly amazing. I recently had major surgery and a friend recommended it to use on my scar. It is a fairly large scar and even though neat I wanted to minimise as much as possible. I started to use this 3 weeks after surgery, straight away it eased the tightness of the scar and smoothed it out, I use twice daily and by doing so it has desensitise the scarring, and hugely minimised the colouring. You can use for acne too I believe so a very handy little bottle to have and it goes a long way so don't be fooled or put off by the size of the bottle. The price I paid was very reasonable against other well known brands for scarring. My operation was 9 weeks ago to date and I have used for 6 weeks so this gives you an indication of how long I have used it for, which is not that long. Well packaged and excellent delivery service too. Hope this has helped you in some way.
