COSRX The Niacinamide 15 Serum 20 ml

The Ultimate Sebum Control: High-Concentration Defense Against Breakouts

COSRX The Niacinamide 15 Serum functions as a highly concentrated, non-comedogenic solution for individuals struggling with persistent acne scars, rough skin texture, and oily shine. Standard clarifying serums often use low percentages of actives that take months to show results. Consequently, this clinical formula combines a maximum dose of Vitamin B3 with synergistic oil-controlling agents. It works immediately to clear away structural dullness, smooth bumpy surface cells, and accelerate the fading of stubborn hyperpigmentation.

Texture, Formula & Feel

Texture: It features a lightweight, fast-absorbing liquid consistency that feels clean upon application. Formula Type: A fragrance-free, non-comedogenic blend dermatologically tested to minimize irritation from high-strength actives. Finish: It sinks into the skin matrix within seconds, leaving a smooth, shine-free matte finish without any sticky residue. Suitable Skin Types: It works exceptionally well for oily, combination, and acne-prone skin types facing stubborn blemishes.

Key Benefits & Powerhouse Ingredients

This targeted clinical serum charges the skin barrier with an intensive oil-regulating matrix:

• Total Blemish Correction: Features 15% Niacinamide (Vitamin B3). Therefore, it effectively reduces active inflammation, fades dark brown spots, and curbs melanin transfer to restore clarity.
• Pore & Sebum Regulation: Contains Zinc PCA (1%). As a result, it safely controls excess oil production, minimizes the appearance of stretched pores, and prevents future acne blockages.
• Acne Defense & Healing: Infused with Allantoin and Zinc Sol. In addition, these soothing agents accelerate cellular recovery and calm raw, irritated skin during active breakouts.
• Hydration Balance: Formulated with Trehalose. Instead of completely drying out the outer layers like traditional acne treatments, it maintains optimal moisture levels to protect your skin barrier.
• Texture Refinement: Furthermore, with regular use, it smooths out rough skin textures, treats uneven tone, and reveals a clear, uniform glass-skin appearance.

How to Use:

1. For a beautifully clear, balanced, and smooth complexion:
2. Prep: Cleanse your face thoroughly and apply a hydrating toner to balance the skin’s surface.
3. Apply: Dispense 2–3 drops of the serum directly onto your fingertips or target areas.
4. Massage: Smooth the liquid gently over your face and neck, avoiding the immediate eye area.
5. Pat: Lightly pat the fluid into your skin using upward motions to assist absorption.
6. Protect (AM): Crucially, if applying during your morning routine, always follow up with a broad-spectrum sunscreen to safeguard your skin.
