Turn on the safe green light! It contains highly-concentrated 10% Centella Asiatica extract, which gives excellent skin calming effect, and hyaluronic acid, which draws in moisture to form a strong moisture layer that calms the skin's heat and tightens pores. It is a safe toner to be used after cleansing to help restore and strengthen the skin barrier. The product is not a common toner that flows like water, but is a jelly-type moisturizing essence formulation.
