Hm, Should I let you know my secret?
The first time I used this product I was flabbergasted.  I had tried other, far more expensive products, and these delivered superior results.  There is a definite tingling after five minutes of application, but the real proof that it works is once you wipe in you see the results.  Bags, shadows, gone.  Okay -- not forever, but for several hours anyway.
