Generally, grapeseed oil is considered one of the lightest body oils due to its thin consistency and quick absorption. Safflower oil and sunflower oil are also excellent lightweight choices that won't leave a greasy residue.

Several oils are known for their lightweight feel on the skin. These include grapeseed oil, sunflower oil, safflower oil, rosehip oil, and apricot kernel oil. They absorb quickly and provide moisture without a heavy, greasy sensation.

For all-over body use, consider jojoba oil or sweet almond oil. Jojoba oil closely mimics the skin's natural sebum, while sweet almond oil is rich in vitamins and minerals, both providing excellent hydration and a healthy glow.

Body oil is generally lighter than lotion, especially if it's a lightweight oil like grapeseed or sunflower oil. Lotions often contain water and emulsifiers, which can create a heavier feel on the skin compared to pure oils.
