DERMA FACTORY Niacinamide 20% Face Serum — 1.01 fl oz Oil-Control, Rose Water Hydration

DERMA FACTORY Niacinamide 20% Serum is a lightweight, high-strength facial serum formulated to help oily and combination skin feel less greasy while delivering hydration from rose water and glycerin.

This concentrated Korean-style serum combines 20% niacinamide with 64.5% Rosa Damascena flower water and 8% glycerin to balance excess oil, refresh the complexion, and layer smoothly into morning or evening routines. The watery, non-sticky texture absorbs quickly, making it suitable under sunscreen or moisturizer for a fresh finish without a heavy residue. Use progressively if you have sensitive skin: start with small amounts and increase frequency as tolerated.

How does this serum control oil without overdrying?

The formula pairs a high concentration of niacinamide with humectant rose water and glycerin to regulate sebum appearance while keeping skin hydrated. Rather than stripping natural oils, the serum aims to refine surface texture and reduce shine, leaving a balanced, comfortable feel.

• 20% niacinamide to help minimize excess shine and improve skin texture.
• 64.5% Rosa Damascena flower water provides lightweight, refreshing hydration.
• 8% glycerin draws moisture to the skin for a non-tight finish.
• Watery, fast-absorbing base suitable for layering under other products.

Is this serum suitable for sensitive or combination skin?

Many with combination or oily skin can benefit from this serum’s lightweight composition, but the high niacinamide concentration means sensitive users should patch-test first. Begin with a small amount and alternate days until you confirm tolerance.

• Start with a pea-sized amount; increase slowly if no irritation occurs.
• Apply after toner and before moisturizer for best layering.
• Avoid mixing simultaneously with strong actives (e.g., pure vitamin C or high-strength AHA/BHAs) until compatibility is known.
• If redness or stinging develops, reduce frequency or discontinue and consult a professional.

How do I fit this serum into my daily skincare routine?

Use the serum after cleansing and toning, then follow with a moisturizer and sunscreen in the morning. Because of its quick-absorbing, watery texture, it sits well under creams and makeup without causing pilling.

• Morning: cleanse → toner → DERMA FACTORY niacinamide serum → moisturizer → sunscreen.
• Evening: cleanse → toner → serum → treatment creams if used → night moisturizer.
• Apply more sparingly in hot, humid climates to avoid layering too many products.
• Adjust frequency for sensitivity: every other day to daily as tolerated.

What practical results can I expect and when?

Results vary by individual and routine consistency; users typically notice reduced surface shine and a smoother feel within a few weeks. Hydration from rose water and glycerin helps prevent a dry, taut sensation while niacinamide supports a more refined-looking complexion over time.

• Immediate: lighter, non-greasy finish and fast absorption.
• 2–4 weeks: visible reduction in excess shine and more even surface texture for many users.
• Ongoing use: improved overall balance between oil control and hydration.

Who is this for: DERMA FACTORY Niacinamide 20% Serum is made for people with oily or combination skin looking for a high-strength, fast-absorbing serum that controls shine while providing gentle hydration. It suits those who prefer lightweight, non-sticky textures and multi-step routines that include toners and moisturizers. If you have very sensitive skin or are introducing multiple strong actives, proceed slowly and patch-test first.
