Hi! When I bought my L'ACRIMA skin care system from the Shopping Channel, the makeup artist (the one from Style By Jury) was saying that no one should use any scrub with particles in it as it leaves tiny tears all over your skin that have to be repaired. Over time this is quite damaging to your skin. It's best to use some sort of facial wash that has exfoliant properties (AHAs, for example) in it or use the glycolic peels, if you wish deeper exfoliation.
Thought I should pass this on, I believe the more careful we are with our skin from a young age, the better it will be when we are older.
