Makeup primer is a preparatory product that is applied after your skincare routine to create an ideal canvas to hold onto whatever makeup comes afterward, like foundation, tinted moisturizer, or concealer. It goes underneath your makeup to help your makeup apply smoothly, stay in place, and give your complexion an even-looking skin tone. Some primers also provide a glow-boost and extra skin benefits like hydration and moisturization. Primers are clear and slippery, almost like a serum, and are used to smooth the skin, fill in lines and wrinkles, and create a less porous surface for your makeup. They are not meant to correct color or even out your skin tone. Depending on the type of primer, you can get many different skincare benefits as well as making your makeup glow. Primers can also help treat specific skin conditions and issues, like dryness, oiliness, blemishes, or the early signs of aging. Applying too much primer can sabotage your makeup look before you ever get to create it, so a little goes a long way. In conclusion, while primer is not a necessary step in your makeup routine, it can be a useful tool to create a smoother, more radiant-looking complexion and help your makeup last longer.
