Waterproof mascara is similar to oil-based paint. It can be “thinned” using chemical-heavy storebought makeup removers, which smell funny and sting my sensitive skin. I learned (from some Ayurvedic health book that I wish I could credit) that because mascara is oil solvent, olive oil, or any oil, works just as well to remove it.
Olive oil is delightfully nontoxic and antioxidant-rich. It moisturizes the delicate skin around the eyes and conditions the lashes. I find it to be a good substitute for eye cream, as well. Use your fingertips or a cotton ball to rub a few drops into the eyelashes then wash with mild soap and water.
*Some high quality olive oils have spicy or peppery flavors. Don’t use these near the eyes, they will sting.
