I tried a sample of this and was immediately amazed at how it helped tighten my skin and made my face a lot smoother and refreshed. It certainly is good value for money.
The product itself is good, however, for a serum it is very liquid and using it for the first time I wasted a lot as it poured out. I have now used an atomiser on the bottle so I now get a fine spray when I use it. A design fault maybe?
