next, you're going to want to let it work on your skin and dry for 5-10 minutes. you'll feel your face tightening and maybe tingling, but don't worry! i tend to crack myself up making faces in the mirror, because there comes a point where you literally cannot move your face. for some (possibly immature) reason, i find that hilarious.
anyway, when you feel that it's done it's work, or you can't take the itching that may occur any longer, rinse it all off your face. there might be some redness, but that's okay. it'll go away. if i have a nasty zit, i might use a little bit of acne cream on that, but otherwise i will leave my face alone afterwards. a bit of moisturizer won't hurt, since this can leave your face a tad dry. for that reason, i wouldn't use this on days that you have no acne. use it when you need it.
i hope you try this out! it might sound weird, but it actually works really well. also, the clay will last much longer than any of your "normal" products.
let me know if you try this, already use it, or have another natural remedy for acne! i'm always into hearing about natural alternatives... i think it's really important! ^.^
