Dr.Althea Tip :
Each sheet holds the equivalent of a full 30g ampoule. Don’t waste the leftover essence; pat every last drop into your skin.
Long day? Your skin feels it too.
Back-to-back meetings.
Dry office air.
A day that just won’t end.
By evening, your skin feels tight, tired, and stressed.
Apply one cooling sheet.
Feel the chill instantly. Watch it turn clear as the essence soaks in. Hello, calm and hydrated skin.
Together, they create a 70% moisture-rich base that refreshes and calms skin when it needs it most. Green Tea Water, rich in polyphenols (plant-based antioxidants), supports a fresh, healthy-looking complexion, while Collagen Water deeply hydrates for smoother, softer-feeling skin.
Like our signature 345 line, this formula combines 3 barrier-care ingredients (Panthenol, Allantoin, Ectoin), 4 moisturizing ingredients (Collagen Water, Beta-Glucan, Kelp Extract, Coconut Oil), and 5 soothing ingredients (Green Tea Water, Madecassoside, Cica Exosomes, Centella Asiatica Extract, EGCG). With water-binding Ectoin and matcha-derived EGCG in the mix, it helps support the skin barrier, deliver deep hydration, and comfort stressed skin.
Tested by the Korea Institute of Dermatological Sciences for temporary skin cooling, 24-hour hydration, improved skin moisture levels, soothing, and skin barrier support.
