I have been using foot exfoliants like this for years.
The watery product comes ready to go in two plastic type socks. I do this at night usually while I have a night of TV watching planned. I also put socks on over the top to keep it all in place.
About a week later my feet peel terribly. It is so disgusting but well worth it. Best done in winter before your feet are on display otherwise it's really embarrassing in the peeling stages! I was at the beach once with the peel happening and I was super embarrassed! Afterwards my feet are always perfectly pink and smooth and look a million times better than having a pedicure.
My favorite part- rubbing my gross peeling feet on my husband at night, it really grosses him out but I find it absolutely hilarious.
Okay, so sitting with your feet inside a mushy plastic bag for two hours isn't that great, but it does force you to chill out for a bit which is nice.
I found the packaging really easy to deal with, and the little tape strips they provided worked really well. Generally, I don't like single use products as they seem pretty wasteful. but I can't think of another way you could make this product so it was less wasteful.
My feet didn't peel until day 6, and when they did, it wasn't as dramatic as I expected. However, the end result has been pretty good, and while it wasn't as good as the website testimonials show, I think I would give it another go.
Tips: I soaked my feet for maybe 5 minutes before putting my feet in the bags, but I really think soaking them for a good 1/2hr would lead to much better results.
