I have little goat feet. I don't moisturize, and I rarely wear shoes. My only foot care is to intermittently scrape off the calluses with a callus remover.
That said, when I was giving myself facials for Opera Month, I picked up a Knock-off Chinese Foot Peel. It's all the craze now: you soak your feet in little booties filled with liquid, then in about four days all the skin on your feet sheds off in sheets and are left with the bare minimum of foot skin.
The most popular brand is called Baby Foot. If you Google images of Baby Foot Peel you will say, "Ugh," then, "More like Leper Foot Peel," and then if you are me you will research up the main ingredient and get very excited about applying leather tanning agent to your feet.
Four days after I used my knock-off foot peel, about half of my problem skin came off as suddenly and dramatically as promised. I wish I'd been strong enough to follow the instructions and not help pick it along. The other half of my hardened callused skin stayed put, giving my soles a nice lunar surface look for Moon Week.
I bought another knock-off brand on Amazon, and after eight days it activated: now I’m down to one-quarter of my problem skin. I can see where this is heading - nail biting, scab picking people like me should not be allowed to purchase this product. They recommend you use this product once every three months. This next one will be my third in three weeks. But I swear I will stop after this next one.
