What is the percentage of salicylic acid and hyaluronic acid in the 42% Urea Gel?

Ingredients are always listed from most to least on a label. Salicylic acid falls in the middle of our list of ingredients, so there's a good amount in there, and hyaluronic acid is last. While we can't share the exact percentage (that's a trade secret), we can tell you that we've included enough of these amazingly effective ingredients to penetrate deeper into the skin, loosening and breaking up old, thick, dry skin. It's part of why this urea gel is so amazingly effective.
