You often see the name Niacinamide on skincare labels; it is included in the basic formulas of dozens of brands. So, what does this B3 vitamin derivative promise for your skin, and at what concentration is it effective?

What is Niacinamide?

Niacinamide (nicotinamide) is the amide form of vitamin B3. It plays a role in the production of NAD+ and NADP+ coenzymes within cells — these two molecules are critical for skin cell energy metabolism, DNA repair, and barrier function.

In skincare, niacinamide is used topically and is one of the most studied actives in international dermatology literature. Clinical studies show the following:

1. Evens skin tone and reduces blemishes. Niacinamide inhibits the transfer of melanosomes (pigment packages) to keratinocyte cells. In 12-week clinical trials, a significant reduction in the appearance of dark spots was reported in subjects using 5% niacinamide.

2. Reduces the appearance of pores. It balances sebum secretion; when excessive oil production normalizes, pores appear smaller.

3. Strengthens the skin barrier. It increases ceramide synthesis. Ceramides constitute approximately 50% of the lipid composition in the skin's moisture barrier.

4. Provides antioxidant protection. It supports against free radical damage.

At What Concentration Should It Be Used?

Clinical studies show that a niacinamide concentration of 2-5% is sufficient for maximum efficacy. Concentrations of 10% and above — marketed by popular "high-strength" formulas — may cause redness or irritation in some individuals and do not provide additional efficacy.

Niacinamide in Maxel JU Formulas

Niacinamide is included in almost all Maxel JU formulas: Anti Aging Cream, Day Cream, Night Cream, Blemish Serum, Blemish Toner, Clarifying Toner, and Facial Cleansing Foam. We clearly display the INCI list of all our products on their respective product pages.

Things to Consider When Using

Used with Vitamin C. The old claim "niacinamide + Vitamin C should not be used" is not scientifically correct; niacinamide can easily be used with modern stable C formulas.

Order: In a routine of toner → serum → cream, niacinamide can be in the toner, serum, or cream. The cumulative concentration is important.

Morning/Evening: Niacinamide is not photosensitive and can be used both in the morning and in the evening.

Conclusion

Niacinamide is an active ingredient that is widely tolerated and clinically proven, to the extent that it can be described as "for all skin types." If you want to start a proper routine, a product containing niacinamide is a good starting point.
