Essential oils should be used before serums Usually, it is better for the skin to use essential oils first and then serums. Essential oils are usually extracted from plants in a specific way, do not contain alcohol additives and other ingredients, and are pure transparent and pure liquids, which are relatively permeable and easily absorbed by the skin. Serums are usually specially processed using various raw materials, adding various emulsifiers and vegetable oils, as well as artificial colors and flavors. If you use the essence first and then the essential oil during makeup and skin care, the essential oil cannot be used well by the body after the essence is absorbed by the skin
In addition, essential oils are easier to penetrate and aid in absorption, so it is better to use essential oils first while the efficacy is the same. The correct skincare sequence is: cleanser, water, essential oil, serum.
