COSRX - The Vitamin C 23 Serum (20ml)

Cleanse your face thoroughly and apply toner (if part of your routine).

1. 
   Apply your face serum first. Dispense 2–3 drops and gently spread it over your face and neck. Pat lightly until fully absorbed.
   
2. 
   Follow with face oil (or use it alone if it's the only treatment). Warm 2–3 drops between your palms and gently press it into your face and neck to lock in moisture.
   
3. 
   Finish with a moisturizer if needed. In your morning routine, always apply sunscreen as the final step.
   
4. 
   Use once or twice daily, depending on your skin type and the product's instructions.
   
5. 
   Avoid direct contact with the eyes and discontinue use if irritation occurs.
   

For Best Results

• 
  Apply on slightly damp skin for better absorption and hydration.
  
• 
  Use only a few drops—more product does not mean better results.
  
• 
  Layer products from thinnest to thickest consistency (serum before oil).
  
• 
  If using an active serum (such as Vitamin C, Retinol, or exfoliating acids), follow the product's directions and avoid combining incompatible actives in the same routine.
  
• 
  Store your serum or face oil in a cool, dry place, away from direct sunlight.
  
• 
  Always perform a patch test before first use, especially if you have sensitive skin.
