Saemmol Jung is a professional make up artist for korean celebrities. Her youtube channel ranges from hair styling to make up tutorials. Here she shares a clever technique using loose eyeshadow to great a soft, flawless gradient effect on nails. Unlike some of her other videos, this one isn't subbed in english. However, the process seems quite easy to interpret. A base coat is laid out and then using a loose eyeshadow, it is dabbed onto the nail tip with a sponge to create the effect. Remove excess powder around the edges with nail polish remover. A sheer polish and then top coat is layered over.
Gonna spend tomorrow digging for some old eyeshadows in my drawers.
