Discovering your skin type is the first thing you should do prior buying any foundation. There are five basic skin types; oily, dry, normal, combination and sensitive. This is skin type that dictates you which type of foundation you should go for.
If your skin is oily, don’t use oil based makeup and beauty products as you will not want to let the bacteria thrive on your skin. Applying oil-base products over already oily skin will turn the skin excessively oily and excessively oily skin provides an ideal surrounding for the bacteria to grow. You should rather go for an oil-free, water-based foundation. You may pick a liquid, cream or powder foundation as per your desire.
If your skin is dry, not oily; never use the beauty products that are formulated in the view of requirements of an oily skin. The reason being, making use of foundation devoid of oil will turn your skin even drier and taut. Hence, find an oil-based foundation for your skin. You can pick any of liquid, mineral or mouse foundation that is oil-based.
Moreover, if you are blessed with combination skin, two types of foundation should be at your hand at a time: one oil-based and one oil-free.
The reason being, as it is combination skin, you can have either dry or oily skin. The oiliness or dryness of skin depends upon the weather; skin experiences dryness in the cold months and turns oily in the hot months of summer. That’s why it is being suggested to have two types of foundation at hand at once.
