Black Castor Oil can be used on callused, dry skin to help soften and moisturize skin. Black Seed Oil can be mixed with a little carrier oil like hypoallergenic Hoba (jojoba) oil for less sticky feel.
For mature (or any skin that needs a boost) use this easy mix: soak 2 tbsp of oatmeal with water, add 1 tsp of honey and 2 tsps of Black Castor Oil. Apply to clean, slightly wet skin, let almost dry and rinse off. Follow up with Hoba Oil before skin dries to lock in the moisture.
Black Castor Oil is known to be an excellent moisturizing oil that also nourishes dry skin and helps fight skin itchiness and dryness.
