At night, after applying lotion, use the spatula provided to dispense an appropriate amount (about the size of a pearl) onto the back of your hand and gently spread it over your entire face. Then, wrap your face with your palms to thoroughly blend the product. *If the container becomes detached due to a drop or other reason, check the four corners of the outer and inner containers, align the straight corners, and push until you hear a click. Please be careful if you have ever had an allergic reaction to the ingredients. Always perform a patch test or other trial before using cosmetics for the first time. <Caution> - Avoid contact with eyes. If contact occurs, rinse immediately. - Do not store in direct sunlight or in high or low temperature environments. - Keep out of reach of infants and young children. - Close the cap tightly after use. - Do not drop or subject to strong impacts to prevent damage. - Keep the spatula clean before use. Before use, carefully check for any abnormalities on your skin. Do not use if you have cuts, swelling, eczema, or other abnormalities. If the product does not suit your skin, discontinue use. If you experience any abnormalities such as redness, swelling, itchiness, irritation, discoloration (white spots, etc.) or darkening during use. If the above abnormalities occur after direct sunlight on the skin where the product was used. If you continue to use cosmetics, symptoms may worsen, so we recommend that you consult a dermatologist.
