I've been using this scrub religiously for the past 3 years. Recently (2012), they updated this scrub's packaging and change the formula by adding grapefruit oil and removing the kumquat oil. The grapefruit oil is a bit strong, but very pleasant smelling.
The formula is still as great as before. If you love having a professional microdermabrasion then this scrub is for you. The scrub is as good as a session with your esthetician, but a lot more affordable.
I know it seems pricey for $75 a small jar, but it will last you a long time and the results are amazing.
