Originally developed by Oregon pharmacist Tara O’Keeffe to repair the cracked hands of her rancher father, O’Keeffe’s Working Hands hand cream is now a part of the Gorilla Glue company. The cream mimics the skin’s natural repair process by drawing moisture into the skin and hydrating it. Ingredients include glycerin and allantoin. The non-greasy, hypoallergenic, odorless formula comes with a moneyback guarantee. A 3.4-ounce jar sold for $7.99 in 2011.
