Description

Derma Factory Niacinamide 20% Serum 30ml is a high‑concentration, water‑type serum formulated to target tone, pore texture, and dullness. It contains 20% niacinamide with 64.5% Damask rose flower water and a lightweight, fast‑absorbing texture for skin that needs brightening and moisture balance. Recommended for shoppers seeking a concentrated niacinamide treatment to add to their serum step.

Key Features

  • Niacinamide 20% concentration.
  • Damask rose flower water (Rosa damascena) 64.5% instead of purified water.
  • Glycerin 8% included for humectant properties.
  • Effective‑ingredient total: 92.5% (Damask rose flower water 64.5% + Niacinamide 20% + Glycerin 8% = 92.5%).
  • Texture: transparent, watery serum that absorbs quickly without stickiness.
  • Color: colorless; Scent: fragrance‑free (unscented).
  • pH: 6.4 ±1.
  • Volume: 30 ml.
  • Brand: Derma Factory.

How to Use

  1. For first use, dispense one pump and apply to skin.
  2. If no irritation occurs, use up to two pumps per application.
  3. After application, finish with a moisturizer to prevent white powdery residue when skin moisture is low.

Key Ingredients

  • Niacinamide 20% — vitamin B3 ingredient for tone and texture care.
  • Damask rose flower water 64.5% — replaces purified water to add soothing/brightening support.
  • Glycerin 8% — humectant to increase and retain skin moisture.
  • Butylene Glycol 5.0% and 1,2‑Hexanediol 2.2% appear among notable formulation components (supporting moisture and preservation).

Cautions

  • High niacinamide concentration — if skin lacks moisture the product may leave white powdery residue; follow with a moisturizer.
  • Sensitive skin: start with one pump; if no irritation, increase to a maximum of two pumps.
  • Avoid using multiple niacinamide‑rich products at the same time to prevent excessive cumulative concentration and poor absorption.
  • When combining with strong actives (retinol, retinal, AHA, high‑dose vitamin C), use caution: consider alternating AM/PM or introducing gradually; high‑strength actives used together can increase irritation.
  • Product raw materials may cause mild natural variation in scent; this does not indicate a quality issue.
  • Day or night use is acceptable—niacinamide is stable with light and heat.
  • Do not mix with 100% powder products (e.g., pure niacinamide powder) as powders may not dissolve evenly and can leave residue or increase irritation.

Korean user insights

What Korean shoppers say about this product

Korean users treat this as a bargain high-dose niacinamide staple: a water-thin, fragrance-light serum that absorbs fast, controls sebum, and calms breakouts and closed comedones for many, cheap enough for face and body. Experiences split on results and tolerance — several saw no real brightening after multiple bottles, and sensitive skin often needs alternate-day use or mixing into cream to avoid stinging.

Commonly praised

  • Exceptional price for a 20% niacinamide concentration
  • Water-light, fast-absorbing, non-sticky feel suited to summer and oily skin
  • Frequent reports of reduced sebum, calmer breakouts, and faded closed comedones
  • Light enough to use on body pigmentation areas as well as the face

Worth knowing

  • Brightening results divide users; some emptied several bottles without visible tone change
  • High concentration can sting or trigger bumps — start small, alternate days, or mix into cream
  • Short pump lets drips crystallize white on the bottle, and it hydrates only lightly, so a moisturizer after is needed
