This recipe is great for removing makeup, even your waterproof mascara and liquid eyeliner!
2 tsp canola oil
1 tbsp light olive oil
1 tbsp castor oil
Combine all ingredients and store in a small container with a lid (a travel size bottle works great).
Put a small amount on a cotton pad or cotton ball, and rub around your eye makeup area to remove. Rinse with water and apply moisturizer as usual.
To be even more environmentally conscious, use re-usable makeup pads that you wash.
