Primers smooth your facial skin so that lines and wrinkles appear lessened – this is a big improvement when applying your foundation. I like to use Color Science Skin Brightening after applying my serums. The following is an article from BeautyLish that I enjoyed and I bet you will, too.
These days, it seems like primers are all over the beauty market. And it’s no wonder—they work! Think about it: it’s normal for the skin’s surface to be textured from pores, fine lines, and inflammation. In other words, the complexion isn’t flat and smooth. So when you apply foundation over bare, un-primed skin, you may find it more difficult to blend the product out. The foundation might then settle into every crevice, accentuating flaws and enlarging the appearance of pores (especially with a heavily pigmented formula). Adding to the challenges of foundation application is your skin type—those with normal, oily, and dry skin will get different results.
Originally, primers were invented to prime the skin for a smoother foundation application, much like you’d use primer on a wall before painting it. Eyelid primers are also popular nowadays, meant to make eye shadows go on smoother and last longer. Whether marketed for the face, the eyes, or both, the anatomy of a primer will be similar.
Key Ingredient: Silicone
Primers form a film on the skin that are usually soft, cushiony, smooth, and silicone-based. Silicone derivatives are used in majority of primers because they provide a slippery feel that helps foundation and cream blushes glide like magic over any skin texture rather than absorbing into the skin. They also help to minimize the appearance of pores and fine lines.
When you look at the label of your favorite primer, you may see many of the following silicone-based ingredients listed. Usually, they compose the majority of the formulation:
cyclopentasiloxane, dimethicone, dimethicone crosspolymer, dimethicone/vinyl dimethicone crosspolymer, phenyl trimethicone, PEG-10 dimethicone, dimethiconol, bis-PEG/PPG-14/14 dimethicone
There are also primers that don’t contain silicone; generally they’re better for good skin that doesn’t require much coverage. Silicone-free primers rely on either gelled oils, which may feel a little greasier on the skin than silicone (with silica) or gelled water-based formulations (with acrylates or C10-30 alkyl acrylate crosspolymer).
