Apply it directly:
The best way to fight dark circles is by directly applying the oil under eyes.
Wash your face and pat it dry.
Take 3-4 drops of castor oil on your fingertips and apply it on the dark circles.
Massage the affected area for half a minute and leave the oil overnight.
Wash it with normal water in the morning.
You could also mix castor oil with a few drops of almond oil, coconut oil, mustard oil, jojoba oil, grapeseed oil and milk for better results.
