You don’t have to be a beauty aficionado to guess the purpose of basic skin care products like cleansers and moisturizers. Let’s face it: The name gives it all away—cleansers help cleanse the skin and moisturizers help moisturize the skin. Duh. While the benefits of many skin care products are pretty self-explanatory, there are others which are not as easy to figure out by name alone. Case in point? Essence. I mean… what is an essence anyway? Keep reading to find out! WHAT IS AN ESSENCE? In a 10-step Korean skin care routine, essence is used after toner and before a facial serum, providing the skin with an extra layer of hydration—and ironically, the product itself is somewhat of a crossover between the two. In terms of texture and application, essences may be similar to that of a toner, yet are formulated to resemble a serum—only, a less concentrated version. As the middle step between toner and serum, essence—which is also sometimes referred to as concentrate—can help prep and prime the complexion for the serums and targeted formulas you may use on a day-to-day basis. Not so confusing now, is it?HOW TO USE ESSENCE Now that we’ve gone over what an essence actually is, let’s discuss how to use one in your routine. As we previously mentioned, essence is a middle step between toner and serum and can help prep the skin for the serums and moisturizers that follow. To use, we like to apply a quarter-sized amount of essence to a cotton pad or ball and gently swipe over our facial contours, just as we would a toner. If you prefer to not use cotton pads, you can also splash the formula directly onto your complexion, or even dispense the product in a spray bottle and mist your face with it. WHY YOU NEED ESSENCE IN YOUR ROUTINE Essence can be a fun way to make your skin care routine more customized in order to help target skin concerns and maintain a healthy-looking complexion. We like to use essence as needed—for instance: if our skin appears extra dry, we add a hydrating essence to our routine—but your essence use is entirely up to you. Just be sure to scan the packaging first to help ensure that you are choosing an essence that’s formulated with your specific skin type in mind. Good news! You don’t need a 10-step skin care routine—or a plane ticket to South Korea—to incorporate this trendy K-Beauty elixir into your daily routine.
