St. Ives has those apricot facial scrubs that are great!! There is one for sensitive skin too..

Just mix a little baking soda with your regular cleanser.

I can not use them they make my face red, I use the Oil of Oly facial cloths they are just enough of a scrub for me.

Roc makes an exfoliator that is gentle, not many grains, I've used it often.

I cant use them either,they make break outs worse and irratate my skin.I prefer chemically exfoliating. I use a product by neostrata that contains 4% PHA (an alpha hydroxy-like product) that leaves my skin smooth as a baby's bottom.

The only scrub I like is Ambi Even and Clear. It isn't overly drying or rough like the apricot kernel scrubs.

Here is a link that might be useful: Ambi

I make my own with lemon and sugar. I have *extremely* sensitive skin, though, so I have to dilute it with water and go easy with the sugar. (Hint - do not use warm water, sugar will melt. Lol.)

I don't have sensitive skin but I do like the Aveeno products with soy and use their face scrub at night, every night. Easy to find at big box stores (Wal-Mart, Target), reasonable price. It seems fairly gentle to me. I think you could probably put a little in your palm and then mix in a little regular gentle cleanser to reduce the number of grains too.
