What is a good foundation that stays on all day?

The first step is to make sure your skin is cleansed and moisturized before you put it on. Then, try using a make-up primer to help keep oil under control and create a smooth canvas for your foundation. Next, make sure you're using a good brand of foundation with decent lasting power. After you have applied your foundation- preferably with a brush or sponge and not your fingers- make sure to set it with a loose powder. Many companies, such as Make Up For Ever, offer "fixing sprays" to help set your makeup. It might help to keep a pressed powder with you during the day to banish shine and keep your foundation set.
