Uslu Airlines BIO ($24) is water-based and uses gnomeic abraders (apparently invisible mini crystals) to peel or exfoliate rather than dissolve aggressively. First of all, this smells pretty good. No complaints. It's fruity. The heavy glass bottle comes with two rolls of cotton rounds. It only takes one round for both hands. Overall I love it. I highly recommend it to everyone.
You wet a cotton pad and then coat each nail. Go slow and wait for 30 seconds. Using the same cotton pad you just rub each nail and rinse with water. Other things you may want to know are: it's safe for pregnant women, dissolves polish without stripping your nails, it's not flammable, it's based on components from renewable raw materials and is biodegradable.
I purchased it from beautyhabit.com.
