Why does Niacinamide make the skin smoother?
The smoothness or roughness of the skin depends on many factors, including the skin's moisture, oil balance, and cell renewal process. Niacinamide acts on various mechanisms in the skin, helping to improve the overall skin structure.
Firstly, niacinamide helps enhance the skin's ability to retain moisture by stimulating ceramide production. Ceramide is an important component of the skin barrier, helping to retain water and prevent moisture loss through the skin's surface. When the skin is well-hydrated, the skin's surface will be softer and fine lines on the skin will also become less visible.
In addition, niacinamide also helps regulate sebum production. When excess oil is well controlled, pores are less likely to become clogged, and the skin's surface becomes clearer. This helps the skin appear smoother and more even-toned.
How does Niacinamide reduce the appearance of enlarged pores?
One of the reasons why many people turn to niacinamide is its ability to improve the appearance of pores. In fact, the size of pores cannot be changed completely as it largely depends on genetic factors and skin structure. However, niacinamide can help reduce the appearance of enlarged pores through some indirect mechanisms.
When sebaceous glands are overactive, excess oil can accumulate in the pores. This causes pores to appear larger and more visible on the skin's surface. Niacinamide helps reduce sebum production, thereby limiting the accumulation of oil in the pores.
Moreover, this active ingredient also supports improving skin elasticity. When the skin structure is healthier, the areas around the pores become firmer, making the pores appear smaller and tighter.
Niacinamide 2% - Foundation for hydrated and stable skin
Niacinamide does not require a high concentration to be effective. At a concentration of around 2%, this active ingredient can help improve the skin's ability to retain moisture and strengthen the skin barrier.
When the skin barrier is strong, the skin is less prone to dryness and less sensitive to environmental factors. This is an important foundation for maintaining stable and healthy skin in the long run.
Niacinamide 2% is often suitable for those who want to maintain healthy skin, especially sensitive or recovering skin. At this level, the active ingredient works gently but still provides significant benefits for the skin.
Niacinamide from 2% to 5% - Improve excess oil and skin structure
In the concentration range of 2% to 5%, niacinamide begins to show a clearer ability to control oil and improve skin structure. This concentration is considered suitable for most skin types by many dermatologists.
At this concentration, niacinamide helps regulate sebum production, thereby reducing oiliness and minimizing the risk of clogged pores. When excess oil is well controlled, the skin's surface becomes smoother and pores are less noticeable.
Therefore, many skincare products aimed at improving skin smoothness and shrinking pores often choose niacinamide within this concentration range.
Niacinamide 10% - When improving skin pigmentation is needed
At a higher concentration, around 10%, niacinamide is often used in products targeting the improvement of skin pigmentation such as dark spots, hyperpigmentation, or uneven skin tone.
Niacinamide has the ability to inhibit the transportation of melanin from melanocytes to the surface of the skin. This can help lighten dark areas over time. When combined with other active ingredients, 10% niacinamide can effectively brighten the skin. However, not every skin type needs such a high concentration. Some people with sensitive skin may feel slight tingling or irritation when using niacinamide at a high concentration.
Understanding to choose the appropriate concentration
One common misconception in skincare is that the higher the concentration, the better the product. In reality, the effectiveness of an active ingredient depends not only on the concentration but also on the needs of the skin and how it is used.
Niacinamide is a prime example of this. For many people, a concentration of 2% to 5% is sufficient to reap benefits such as improving skin smoothness, controlling oil, and reducing the appearance of enlarged pores. Using a higher concentration should be considered based on specific goals, such as improving pigmentation or addressing more advanced skin concerns.
Beautiful skin does not just come from a percentage
Ultimately, the most important thing in skincare is not choosing the highest concentration of an active ingredient, but selecting products that meet the specific needs and conditions of your skin.
Niacinamide, whether at low or high concentrations, remains a valuable ingredient in skincare when used correctly. When the skin is well-hydrated, oil is controlled, and the skin barrier is healthy, the skin's surface becomes smoother and pores appear smaller and more refined.
A scientific, consistent, and tailored skincare routine always brings long-lasting results compared to chasing after percentage numbers on product labels.
