what is face primer

A face primer is a cream or liquid product applied to the face before makeup to improve coverage and lengthen the amount of time the makeup lasts on the face. It can be used to smooth out pores, create a base for long-lasting makeup, manage oily skin, or prevent excessive shine. There are different types of cosmetic primers such as foundation primer, eyelid primer, under-eye primer, lip primer, mascara primer, and mattifying primers. A foundation primer may work like a moisturizer, or it may absorb oil with salicylic acid to aid in creating a less oily, more matte appearance. Some contain antioxidants such as A, C, and E, or other ingredients such as grape seed extract and green tea extract. There are water-based and silicon-based foundation primers. Ingredients may include cyclomethicone and dimethicone. Some primers do not contain preservative, oil or fragrance. Some may also have sun protection factor (SPF) . Primer fills in fine lines and blurs imperfections, and with a smooth, even surface, makeup products will apply more easily. Since youll need to use less makeup, it can also make the makeup look more natural and last longer.
