In the ecosystem of specialized active ingredients, Niacinamide (Vitamin B3) is positioned as the most versatile "cell-communicating ingredient." However, the wide range of concentrations, from 2% to 20%, often leaves beginners feeling lost in a "maze" of choices.

To optimize treatment effectiveness while preserving the stability of the skin's protective barrier, the use of Niacinamide should be based on a scientifically-backed adaptation roadmap.

1. Understanding Niacinamide: How it works on the skin

Niacinamide is not an abrasive active ingredient; it functions as a cell-communicating ingredient.

👉 Improves pore size: By keeping pores clear and regulating oil, it helps prevent pores from enlarging due to excessive sebum accumulation.

👉 Brightens and fades dark spots: Niacinamide inhibits the transfer of melanosomes to the skin's surface, helping to fade post-acne marks and even out skin tone.

👉 Strengthens the skin's protective barrier: Stimulates the natural synthesis of Ceramides, enhancing skin health and significantly improving conditions such as acne, flaking, and redness.

2. Is 20% too much for beginners?

Typically, concentrations between 2% - 10% are considered suitable for introduction. However, for the characteristic oily and acne-prone skin of Vietnamese people, or skin that has had basic exposure to skincare, 20% Niacinamide is a "breakthrough threshold" for addressing stubborn issues.

4. Important notes to avoid "risks" when using Niacinamide

To achieve the best results when using Niacinamide as a beginner, you need to keep the following notes in mind:

Slight tingling sensation: With a 20% concentration, a slight tingling sensation in the first 30 seconds is completely normal for some sensitive skin types. If your skin becomes red, itchy, or burning, rinse immediately with cool water. However, oh!oh!'s Skin Health serum usually overcomes this issue due to its smart formulation, which is suitable for all skin types, including sensitive skin.
