You’ve gotta check out the stuff this promises to do! It’s almost marketed like black-magic in a jar, to go with that- an equally hefty price to support that ridiculous claim! Since I was absolutely certain that time travelling to the past & regaining my glorious younger skin is impossible, whatever EL’s marketing may claim; I did not buy this on my own accord! I tried this product only because I received this as a sample when I purchased the Estee Lauder Advanced Night Repair Serum.
