How do I use cuticle oil? Oh it's easy. Twist & click the pen then swipe a few drops on each nail and cuticle and massage into the skin to help improve blood flow. A little bit of daily luxury. Cuticles tend to get dry due to exposure to handwashing, dry air, and harsh cleansing agents, so actively moisturizing them with cuticle oil is super important. Daily use of cuticle oil is really the foundation to promote strong healthy nails.
