You should only really exfoliate once or twice a week. Exfoliators are designed to buff away the dead skin cells, leaving you with lovely, bright, fresh skin but if you're doing it too regularly there's no more dead skin cells to take away so you're just aggravating the skin. Eek! Also, if you are going to use quite an abrasive scrub then I'd suggest using a moisturiser with an SPF afterwards (or the next day, depending on when you use your exfoliator).
I'd recommend this if you're a fan of the LE products and if you have dry/sensitive skin as it is absolutely lovely and leaves my skin feeling smooth. This is quite a gentle product, so you may not get the really smooth and bright effects that you do with a more abrasive product but it does an excellent job.
One of my favourite products, it really does give you fresh and bright skin.
Kiehls Rare Earth Deep Pore Daily Cleanser isn't actually meant to be in this group, but its a nice "daily" product meaning that it's more of a cleanser with fine exfoliating beads thrown in. It contains clay so is perfect for oily skins, and just gently cleanses the skin of impurities. This can be used every day, due to the fact that it's not actually an exfoliator and won't really aggravate the skin after continued use.
You're meant to leave this on for a few minutes to let the warmth get into the pores but I can very rarely be bothered. I'll definitely be repurchasing this as I don't own anything similar.
