A lightweight, hydrating liquid toner combining Skin1004’s signature Hyalu‑Cica™ complex (Centella Asiatica Leaf Water + multiple types of Hyaluronic Acid) with gentle exfoliating acids (AHA and LHA). The Centella water makes up around 74% of the formula, helping to soothe and calm irritation. 

Hyaluronic acids work at different molecular weights to provide multi‑layer hydration—so it hydrates deeply and helps replenish moisture from top surface to somewhat lower layers. For exfoliation, the toner uses AHA (citric acid) to help remove dead skin cells on the surface, smooth texture, brighten dullness, and help with uneven tone; and LHA (Capryloyl Salicylic Acid) for more gentle exfoliation, helping with congestion in pores. 

In addition to exfoliation and hydration, the formula includes skin‑brightening / barrier‑supporting ingredients such as niacinamide, Ceramide NP, and adensosine, which help even out tone, strengthen the skin’s barrier, reduce irritation, and improve elasticity.
