How do I apply this oil most effectively, especially if it's solid at room temperature?

Because it is made from 100% unrefined cocoa butter, this oil will be solid or very thick at cooler room temperatures. To apply it effectively, scoop or pour a small amount (a pea-sized portion is often enough for a localized area like elbows or hands) into your palm. The warmth of your hands will quickly melt it into a spreadable oil. As the product description notes, it "melts on contact with warm skin" and then spreads easily.

For optimal results, apply it to skin that is either slightly damp (just patted dry after a shower or bath) or completely dry. Gently massage it into the skin using circular motions, focusing on areas that feel dry, rough, or tight — such as elbows, knees, heels, and hands. The massaging action helps the oil penetrate while also providing the comfort of a massage, another use case mentioned for this product. Since it forms a protective layer, you do not need to use a large amount; a thin, even layer is sufficient. It’s particularly well-suited for an evening routine after a shower, as the residual skin warmth aids absorption and the oil can work overnight.
