After using the evening skin/toner, take an appropriate amount at the essence stage and gently apply along the skin texture and pat to absorb. ※ When using for the first time, we recommend using it every other day or using a rice grain-sized amount for about 1-2 weeks for an adaptation period. ※ After your skin adapts, gradually increase the amount or frequency of use. <Precautions and instructions for use> Do not use if you are pregnant or breastfeeding. Do not use with exfoliating ingredients such as AHA or BHA as it may irritate the skin. (Be careful of the ingredients in cleansers, exfoliating toners, etc.) Because the product is highly sensitive to sunlight, we do not recommend using it in the morning and recommend using it in the evening. Be sure to use sunscreen the day after use. Temporary exfoliation may occur during the initial adaptation period. Do not forcibly remove the dead skin cells and moisturize sufficiently. This product requires an adaptation period when using for the first time. After adapting to it with a rice grain-sized amount, gradually increase the amount and frequency of use.
