- For healthy skin, add rosemary oil to the bathwater.
- Another age-old tradition to prevent wrinkles around the eyes is to apply a drop of castor oil around each eye before going to bed. Castor oil acts as a humectant, meaning that it attracts and retains moisture in the skin. This promotes healthier skin cell rejuvenation. Some plastic surgeons apply castor oil around an incision after surgery for this exact reason.
