It has 85% Houttuynia Cordata Extract for pore cleansing and skin trouble relief and 9.7% Tea Tree Extract as a natural disinfectant. The smell is earthy or leafy, and the texture is slightly thick but turns watery as you spread it. The serum is easily absorbed and soothing throughout the day. It is not sticky or irritating at all. My pores looked less visible the next day.
