What is this product?

A cooling mousse-format toner built on humectants (glycerin, trehalose, multiple hyaluronic acid forms) with soothing extracts like Centella Asiatica and Houttuynia Cordata placed mid-list. Best suited to dehydrated, oily, or combination skin that wants a light, water-based prep step, but note it contains denatured alcohol and added fragrance.

What makes it different?

The formula pairs a large cooling-type humectant base with four hyaluronic acid related ingredients (Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid) spread through the mid-to-late portion of the list. Soothing botanicals, including Centella Asiatica Extract at 24 and Houttuynia Cordata Extract at 25, sit mid-list, while Ceramide NP (44) and Panthenol (42) appear in the later half. Unlike many plain water toners, it also includes a small late-list amount of a skin-barrier lipid and a cooling-agent-led front section that defines the mousse texture.
