Though they often whisk together bowls of liquid chocolate, scented jellies, and fresh lime juice, these professionals don't make desserts. They're nail techs, and they use such sweet ingredients to more effectively pamper appendages during manicures and pedicures at Harmony Nail Spa. For instance, during a jelly pedi, a foot soak made of light, fluffy jelly retains its heat longer than its watery counterparts, extending the soothing effect of the essential oils and aloe vera extracts contained within. Staff members also soothe bodies with hot- or cold-stone massages and smooth skin with waxing services.
