Diane ZusmanI have been a pastel artist for years. The first thing that was suggested to me was to use Gloves in a Bottle prior to painting. Well I bought my first bottle immediately and have been using it since. Before starting any pastel session I apply a very small amount to my hands, under my nails and let it dry. The pastel chalk does not embed under my nails and rinses off easily and completely when I wash my hands. I also like that it protects my hands from drying out and I am certain provides a bit of protection from the chemicals that are in pastel. I love this stuff and a little goes a long way.
