COSRX The Niacinamide 15 Serum delivers targeted support for acne-prone skin with a clinically high 15% concentration of niacinamide, effectively reducing inflammation and regulating sebum production for a clearer complexion.

We value this serum for its precise formulation that balances potent, synergistic ingredients to enhance skin clarity and strengthen the skin’s barrier function. The lightweight texture absorbs quickly, leaving the skin feeling hydrated without any residue or heaviness, making it suitable for layering within a skincare routine.

Key Ingredients:

  • Niacinamide (15%): Reduces inflammation, minimises pores, and regulates excess sebum to control acne breakouts.
  • Acetyl Glucosamine: Promotes skin brightening and evens out skin tone by supporting natural exfoliation.
  • Zinc PCA: Helps balance oil production while providing antimicrobial properties to prevent further blemishes.

How to Use:

  1. Apply 2-3 drops to clean, dry skin after cleansing and toning.
  2. Gently pat the serum across the face, focusing on areas prone to blemishes.
  3. Follow with moisturiser and sunscreen during the day.

The Ritual Tip: For optimal results, incorporate this serum into both morning and evening routines consistently, and allow it to fully absorb before layering other products to maximise its anti-inflammatory and pore-minimising effects.

Very Impressed, Great Deal
Color: Black, Size: Large
Purchased this as a gift for my travel clients who are going to Greece and I am so glad I did! At $9.99, it is such a great deal! And I love that it has RFID blocking, as well as a Bluetooth tracker, just in case. I'm excited to hear feedback from them and hoping the bluetooth tracker actually works! But so far, very impressed.
