I received a sample of this product in one of my Birchboxes during the warmer seasons, and to be perfectly honest, it sat in my vanity until the weather got colder. I actually forgot I had the sample until cold weather and harsh winds started to leave my hands dry and cracked. Enter J.R. Watkins Hand & Cuticle Salve. It has saved me this winter! For a person who normally has very dry cuticles and knuckles, I haven't experienced a single crack yet this winter. I keep the sample in my purse, and a full-sized product both at home and at my office. A must-have for cold, dry winter weather!
