Put the cap on and shake gently several times to ensure the liquid reaches the tip of the brush before use. When using for the first time or if color does not come out easily, lightly press the base of the brush against tissue paper to ensure the liquid reaches the tip before use. Please be careful to check for any abnormalities on your skin. If the product does not suit your skin, or if you experience any abnormalities such as redness, swelling, itching, irritation, discoloration (white spots, etc.), or darkening on the skin during or after use, or if similar abnormalities occur after exposure to sunlight, discontinue use and consult a dermatologist. Continued use may worsen the symptoms. Do not use on areas with cuts, swelling, eczema, or other abnormalities. If the product gets into your eyes, rinse immediately with water or lukewarm water. Do not store in extremely cold, hot, humid, or direct sunlight, or in places accessible to infants and young children. After use, close the cap tightly and store. Leaving the product with the cap removed may cause the brush to dry out and become unusable. Store it horizontally. Shaking or dropping the brush may cause the liquid to leak, staining the inside of the cap or your clothes. Please note that if the liquid gets on your clothes, it may not come off easily. Please note that if foundation, sweat or sebum gets on the brush, it may make it difficult to dispense the liquid or cause clogging. If this happens, gently wipe it off with tissue paper or similar and use it after cleaning. This product contains cochineal pigment.
