Now, Procter & Gamble has launched Dawn Hand Renewal with Olay Beauty, which the company says will transform the look and feel of your hands in just five uses, aided by enzymes and a unique surfactant technology. It works by sealing moisture in your hands while you do dishes. I have not tried this product but I like the idea of a detergent that protects my hands while I use it.
I'll put it on the list for the next time I need dish detergent. In the meantime, I try to rinse and dry my hands thoroughly after dishwashing, and apply hand lotion throughout the day.
