This product has two layers, so shake well before use. Use as the final step in your makeup routine. Close your eyes and mouth, hold the spray bottle about 20cm away from your face, and spray evenly over your entire face. After spraying, allow it to dry without touching your skin. After use, wipe the nozzle of the spray bottle clean and close the cap tightly. The contents may dry and harden around the nozzle, making it difficult to dispense as a mist. Continuing to use the product without shaking it well may prevent it from spraying as a mist. When the amount is low, move the dispenser head to align the nozzle and the end of the tube inside the container, tilting it so that you can use it all without waste. Do not inhale directly. After long-term storage, or if the mist spreads narrowly or the contents become difficult to dispense, spray a few times onto a tissue to check the mist spread before use. The two layers may appear cloudy, or there may be a difference in appearance before and after mixing, but this does not affect the quality. Due to the nature of the product, the texture of your makeup may change. At low temperatures, the product may become cloudy or difficult to mix. Leave it in a warm place (room temperature) for a while to return it to its original state, then shake the container well before use. Be careful as it may make surfaces slippery if it gets on the floor. (If it does get on surfaces, wipe it off with detergent.) Do not use in a room where a fan heater that draws in indoor air is in use. Some of the ingredients may be drawn into the fan heater, causing ignition failure or extinguishing the flame.
