Never apply makeup without washing and cleansing your face. Wash your face with a gentle cleanser before you start. Use cold water or any regular lotion on a cotton swab to clean any residual makeup from your eyes. If you have dark circles or dry skin underneath your eyes then rub a little moisturizer on the damage areas around your eyes. Never apply moisturizer on your lid, it will make it greasy and makeup you put on will run off.

Apply primer on your eyelid before applying base (optional). It creates a barrier between your skin and makeup, seals away the oil of your skin from eye shadow. Primer provides protection against fading or creasing of makeup for long lasting wear.

Now select a form of base either cream or powdered. Choose a shade closer to your complexion. Test a variety of base colours before selecting the right one for one.
