@yuzi.kpharmacist: Using COSRX Vitamin C 23? Save these 7 tips 🍊 1. Just 2–3 drops. 2. Use acids and retinol in a separate routine. 3. Patch test first. 4. Cleanse → toner → vitamin C → moisturizer. 5. Daytime? Finish with sunscreen. 6. Refrigerate after opening. Keep upright and tightly closed, away from heat and sunlight. 7. Use within 2 months. Write the opening date on the bottle. Noticeably darker? Replace it. Save this before you open your bottle 🤍 #VitaminCSerum #KBeauty #koreanpharmacist #Cosrx
