Forms of Mascara 

There are 3 different forms of Mascara - water based, water proof and the mixed variety. Mixed variety is the the most useful one. Water based mascaras can be applied quickly and removed easily. So they are gentle to the lashes and eyes. But they won't stay for a long time, as the mascara smudges easily when it comes into contact with water, tears and perspiration.
Water proof variety stay for a long time and is water proof and smudge proof. They are a good investment as they are resistant to contamination and can be used even years after they have been manufactured. But it takes a long time to dry and is difficult to remove the liner. The mixed variety is a combination of water based and water proof mascaras. These dry quickly and is easy to remove. 

Application 

Apply mascara by looking straight into the mirror, with your chin lifted slightly so you can see your lashes clearly. Gently twist the spiral brush as you withdraw it from the masara bottle. Stroke your upper lashes evenly from their base to the tips, curling them upward with the brush as you apply the mascara. Apply mascara to the lower lashes with downward strokes, wiggling the brush back and forth a bit to separate the lashes. After you have applied the mascara to both eyes, you can repeat the application to add more fullness to your eyelashes.
