#7 Determining your skin type
This may be one of the most important tips of all.
Not knowing your skin type will cause so many problems for you when selecting a foundation or concealer.
It took me until recently to figure out my skin type. I always thought I had extremely oily skin, however I realized that my skin is combination, due to my skin drying out from western New York winters.
There are so many products that only work for particular skin types. Some foundations that work for oily skinned people, may make those with dry skin look cake. Some foundations that work for dry-skinned people, may slide right off of oily skin.
Determining your skin type will help you find a product that works for you and will save you a ton of money in the long run, especially being that some foundations can be very pricey.
Trust me, I have learned the hard way.
