@KiwiMoose , I read that article you referenced. I don't know what to think about their position on "physical" exfoliants.
I have been using a pretty scrubby exfoliating cloth on my face every single day for about the last five years. I swear on my life, if I skip two days, my skin on my face looks tough and tired. So, Dr. Dendy Engelman and Dr. Orit Markowitz will have to drive over to my house and personally rip my exfoliating cloth out of my hands! Even if they do, I'll just drive to the store and get myself another one.
My sister in law told me she feels like someone went over her face with a cheese grater if she uses an exfoliating cloth of any type. She regularly does chemical peels. So, I assume there are all sorts of skin textures. I've always thought I had kind of tough skin.
So, I don't know. I don't have any ground apricot shells, but I do have ground lemon peels and ground walnut shells that I have bought but not yet tried. The ground lemon peels look a little chunky to me. I think I'd probably grind them up more before using them. But, the ground walnut shells are really fine. As is the luffa I have, and this Celestunian sand. I've made quite a bit of soap with ground espresso beans (so, not grounds from drip coffee, but like what's left after I make an espresso.) I sometimes wonder if that's too fine, but everyone I've given it to seems to like it. So, I don't know what to think.
What does anyone else think about physical exfoliants on the face?
