FREEORR Urea Cream 60% with Salicylic Acid 2% Foot Care Stick, Deeply Moisturizing and Hydrating Foot and Hand Balm, Gentle Exfoliation Anti-Cracking Foot Cream. This urea cream has quickly become one of my favorites! The stick makes this easy to apply with a simple rub over the area I want to moisturize. It has a creamy texture that feels light and absorbs into my skin quickly. It doesn't leave a greasy or sticky residue. It's gentle on my skin but effective at softening dry rough patches on my elbows, knees, and heels. My skin feels smoother and softer. It doesn't have a strong scent or really any scent that I could tell. Great value!

Anti Crack Cream

Color: 2pcs

As a first time user of O’CHEAL Anti Crack Care Cream…Wasn’t too satisfied with this product! The Peach scent wasn’t as solid as the original. I had a difficult time pulling the cover off and the stick broke…making application really messy! Product did not live up to the advertisement!
