i try and stay away from mono's because of the vachetta so i only have one bag with vachetta and thats my mizi. i'm mot really sure how i should carry it though because i know that our hands get oily but i also lather myslef with coco butter because i have dry skin so i'm also afraid to put it in the crook of my arm. i just ordered a bottle of shining monkey but as i've read it doesn't stop the patina only slow it down. i'm wondering if there is anyway to get the vachetta treated so it doesn't get any darker?
