Essences are highly-concentrated treatments that use active ingredients like hyaluronic acid and glycerin to help nourish the skin after cleansing. Essences come after toners and before oils, ampoules, serums, and moisturizers. They also balance the pH levels of your skin after cleansing and prepare it to better absorb treatments. Their main benefit is to nourish and hydrate the skin. As there are many different essences out on the market, it can get a bit overwhelming to find the right one. Therefore, to get the full effect it is important to know your skin type.
