Rule # 1 Always consider skin type when choosing a foundation

Most skin types can be grouped into one of the following categories: oily, dry, normal, or combination. If you have oily skin, do not choose a foundation that is oil based (or contains it). Also, a powder isnt the best choice for dry skin, try a cream or a mineral foundation. It'll add a healthy glow to dry skin.

Rule #2  Always consider the amount of coverage you want

If you have blemishes that need to be covered, then a powder usually doesn't pack the power needed to do so, a cream or liquid foundation should do the trick.

Rule # 3 Only buy what you will wear

Don't purchase what will only sit on your counter and never be used. Be sure to get a product that is practical for your lifestyle.
