I usually mix this by guess, but this is probably close...
1/2 cup of sugar
1/4 cup of oil (you can use whatever you have, baby oil works well, or I like to use canola or olive oil)
A few drops of fragrance oil
I keep a collection of fragrance oil on hand - they have amazing dupes of designer fragrances at www.naturesgardencandles.com and I use them for scrubs, soaps,candles (just make sure they are body safe) or you can use essential oils... you will still get the silky skin without fragrance oil, but you will have silky skin and smell divine if you add some!
When you mix it it should be almost a paste. Then just grab a little and rub gently - it sloughs away dry skin and I usually shave with it too, it leaves my legs feeling amazing. Towel off briskly when done - you shouldn't need any additional lotion - it leaves my skin really soft. I only use it on my body - it might be too harsh for the delicate skin on your face.
