Hyaluronic Acid Toner Plus is the thicker member of the Isntree hyaluronic acid toner family: an essence-textured toner that pours slowly and clear, closer to a light ampoule than to water. It goes on straight after cleansing, either swept over with a cotton pad or pressed in with clean palms.
Five hyaluronic acid materials appear on the list, from sodium hyaluronate through two hydrolyzed forms to a crosspolymer, alongside sodium PCA, betaine, trehalose, glycerin, panthenol and beta-glucan. Seven botanical extracts fill out the base: green tea, licorice root, chamomile, rosemary, Japanese knotweed, centella asiatica and Baikal skullcap.
What sets it apart from the standard Isntree toner is body rather than the acid count, since both carry the same five materials. Cellulose gum and biosaccharide gum-1 give this one enough weight to linger a moment instead of running off, which is why Isntree points it at dry, tight-feeling skin and allows it as a second layer over the lighter bottle.
It is a hydration step and not a moisturizer, so most routines still want something richer on top, particularly in dry air. No parfum, essential oil, ethanol or silicone appears anywhere in the formula. 200 mL, and a small amount goes further than the texture suggests.
