Teriffic. I apply this in the shower after cleansing my face about once a week. I leave it on while I wash my hair etc., then massage the granules into the skin and rinse. Purchased at Macy's. It does tingle a tiny bit, but nothing bothersome or severe. I have very sensitive skin and this does not upset my skin if used weekly. Leaves a glow and very soft, smooth skin behind. Make sure to use an SPF daily if using this, as it does contain AHAs.
