If you wish to have unscented hand lotion, you can skip this step. Some essential oils are good for the skin. For example, rosemary and tea tree oil are anti-inflammatory. Pomegranate seed oil has anti-aging qualities. Cedarwood reduces irritation, and ylang-ylang is an effective cleanser. The best herbs for lotions are calendula and chamomile. They are good for dry skin.
If you want a natural-scented lotion (coconut oil and shea butter), you can skip this step.
