The Dr. DANA Nail Renewal System is a three-step system that will leave your nails with a healthy-looking, youthful, and hydrated appearance. Step 03: Hydrate is the third and final step to gorgeous-looking nails. The deep-hydration formula is a luxurious, quick-absorbing nail and cuticle moisturizer. This innovative gel-oil hybrid (joil) formulation contains a proprietary Phyto Crystal Complex, which is comprised from the sap of a very unique French evergreen tree. In a consumer use survey, when the full three-piece system was used after one, two, and three applications, the majority of participants agreed that their nails appeared stronger. How do I use it: Twist pen until product saturates applicator tip. Brush on generously onto nails, cuticles, and surrounding skin. The system was designed to be used once a week; however, if your nails are very dry and brittle you can opt to use Step 03 more often, as it will provide instant hydration. It's also an ideal cuticle moisturizer that can be used daily. From Dr. DANA.
