What it is

DERMA FACTORY Niacinamide 20% Serum 30ml is a candidate when you want a clearly stated concentration. Compare it with the strength and amount of a serum your skin has previously tolerated. A higher number does not establish a better choice for everyone.

A list starting with Rose Flower Water

The official 30ml list starts with Rosa Damascena Flower Water, Niacinamide, Glycerin and Butylene Glycol. It also includes 1,2-Hexanediol and texture-adjusting ingredients. A shorter list does not mean plain water or guaranteed irritation-free use. Rose Flower Water is different from a Fragrance entry, yet remains relevant to known reactions.

Twenty percent converts to 200,000ppm; it is not an absorption percentage or an improvement rate. A retailer displays an additional Water entry. This guide follows the official 30ml list, while your purchased package takes priority if the label changes.

Compare before adding powder

The brand warns that adding niacinamide powder can cause stinging or redness and recommends using the supplied formula. Do not read its concentrated format as a reason to intensify it further. Apply an appropriate amount gently and stop additional application if it feels uncomfortable. When comparing a dark-spot serum, consider the accompanying ingredients and directions alongside the niacinamide figure.

A buying question answered

The brand advises using the serum as supplied because adding powder can cause stinging or redness. The 20% label is not a reason to increase it further. Rose Flower Water is a distinct ingredient to check if relevant to past reactions. Adjust amount and frequency according to your package directions.

Use and comparison choices

Spread an appropriate amount gently along the skin texture. Let it absorb and follow with moisturizer as needed.

ma:nyo lists Niacinamide 50,000ppm, equivalent to 5%, with other active entries. Compare concentration, complete formula and its shake-before-use directions.

Compare S.NATURE Aqua Squalane Moisturizing Cream 60ml for a separate moisturizing step. Choose according to tight areas and the amount of moisture needed. Consider each product in its intended stage instead of mixing formulas.

Key ingredients

NiacinamideEWG 1
A form of vitamin B3 that acts on the step where melanin transfers into skin cells, which is the basis for its use in tone-evening products. Research also covers barrier lipid production and oil control, giving it unusually broad application. In Korea it is a listed brightening functional ingredient, commonly at 2 to 5 percent.
Glycerin
The most widely used humectant in skincare, drawing water toward the skin and holding it in the upper layers. Its interaction with the skin's own water channels has been studied for decades, and it is mild enough to appear across a very wide concentration range. At high levels it turns tacky, so formulas usually pair it with lighter humectants.
