This was the first time that I have used the Skinfood Mint Sparkling Foot Peeling Socks. I have peeled with a different brand once before. I soaked my feet in warm water for about 10 minutes before putting on the socks, and I left them on for about 20 minutes longer than the instructions said. It took about 3-4 days for peeling to start, and I have had some big peeling bits and lots of smaller flakes come off. My feet aren't perfectly smooth, but it's done a great job and I would buy again. The socks are generously sized and my size 9 (north american sizing) feet fit comfortably.
