1. Place the foundation in the RMK Foundation Case (sold separately). 2. Remove the inner tray from the refill by pinching it with your fingers, place it in the case, and gently press down with a tissue or similar. To remove the inner tray from the case, use a pin or similar to push it up through the hole on the back of the case. 3. Choose either the RMK Powder Foundation Brush or the RMK W Sponge (sold separately), remove them from their packaging, place them in the case, and place the transparent sheet on top. 1. Prepare your skin with a makeup primer before use. 2. Depending on your desired finish, you can use either the brush or the sponge (sold separately). <For a soft, light finish> We recommend the RMK Powder Foundation Brush (sold separately). Apply an appropriate amount of foundation to the brush and apply it by stroking from the center of your face outwards. <For a moist, lustrous finish> We recommend the RMK W Sponge (sold separately) (two-sided sponge and brushed puff). Apply an appropriate amount of foundation to the sponge and spread evenly from the center of your face outwards. To finish, use the puff to gently buff around your cheeks for a more even application and a natural glow. <Notes> If the sponge (sold separately) becomes dirty, gently wash it with warm water and a mild detergent, then rinse thoroughly, dry with a towel, etc., and be sure to dry it in the shade. If the sponge is scrubbed too hard or is dirty, the foundation will not adhere well. Always keep it clean. If the brush (sold separately) becomes dirty, gently shake it in warm water and a mild detergent, rinse thoroughly, dry with a towel, etc., gently reshape it, and be sure to dry it in the shade completely. Please note that dropping or subjecting it to strong impacts may cause the foundation to crack. Do not use on areas with cuts, swelling, eczema, or other skin problems. Check your skin carefully before use to ensure no abnormalities have occurred. If the cosmetics do not suit your skin, discontinue use. 1. If you experience any abnormalities such as redness, swelling, itchiness, irritation, discoloration (white spots, etc.) or darkening during use. 2. If the above abnormalities appear on the skin after use and exposure to direct sunlight. Continuing to use cosmetics may worsen the symptoms, so we recommend consulting a dermatologist. Be careful where you store them to prevent accidental ingestion by children or people with dementia. Be careful not to get them in your eyes, and if they do get in your eyes, rinse them thoroughly immediately. Close the lid tightly after use.
