1) Your Skin Type
Knowing your skin type is very important when choosing a base for your face. This will determine how well the foundation will perform, last and look. So if your skin is dry, oily or a combination of both, you want to choose something that will help to alleviate those issues. For dry skin use oil based liquid or cream foundation to hydrate the skin why keeping the dryness at bay. For oilier skin, use a water based liquid foundation, cream to powder or pressed/loose powder foundation.
