My mum always told me to make sure everything was definatly finished before throwing it away, it started years ago when I had my L'Oreal kids shampoo and carried on from then.
Me and my older sister were always told to cut the bottle when it's started to get empty, then fill it with water and use what's left.
Most skincare and beauty products come in plastic bottles which are surprisingly easy to cut open. Most people just take the lid off and give it a shake but you'll get much more out of it by cutting it open.
Please be careful when cutting your product open!
