When you think your tube of cream (or whatever) is empty, cut off the end of it and look inside to be sure (you will probably find there is a lot of stuff clinging to the sides and in the “shoulder” of the tube.
I use Strivectin. (I have read the ingredients, and it is natural, as far as I am concerned right now at this moment, and it helps my complexion.)
Strivectin is the most expensive skin cream I have ever bought, but I noticed a serious difference when I stopped using it for 4 months, so I am back using it. I should not complain — the stuff lasts forever (I do use it 3 times a day).
The part where it is hard is when the tube is at the end, and I am going to have to buy more, i.e., sacrifice around $150 dollars (if I count the tax). This time, I’ve gone ahead and bought the new tube, but I haven’t opened it yet. I just wanted to see if I had gotten all of it out of the tube, so I cut off the end of the tube, and looked inside — nope!!! there was a lot of Strivectin clinging to the inside of the tube. I wiped out some and used it. When I could not reach the cream anymore, I cut the tube again. I’m going on week two and there is still more down there.
