Niacinamide, also known as Vitamin B3 or Nicotinamide, is one of the most extensively researched ingredients in modern dermatology. It is widely recognized for its ability to improve the skin barrier, regulate sebum production, reduce redness, improve skin texture, and brighten uneven skin tone.

Niacinamide supports the production of ceramides and essential lipids within the skin, helping maintain hydration and protecting against environmental stressors. It is suitable for most skin types, including oily, acne-prone, dry, combination, and sensitive skin.

Because of its excellent compatibility with other active ingredients, Niacinamide is frequently combined with Hyaluronic Acid, Vitamin C derivatives, Ceramides, Peptides, and Retinoids in advanced skincare formulations.

• Strengthens the skin barrier

• Helps reduce transepidermal water loss (TEWL)

• Controls excess sebum production

• Minimizes the appearance of enlarged pores

• Improves uneven skin tone

• Helps reduce post-inflammatory hyperpigmentation

• Supports smoother skin texture

• Helps reduce redness and irritation

• Improves skin hydration

• Suitable for daily use on most skin types

Multiple peer-reviewed clinical studies have demonstrated that topical Niacinamide improves skin barrier function, reduces sebum production, decreases transepidermal water loss (TEWL), improves hyperpigmentation, minimizes the appearance of enlarged pores, and supports overall skin health.

Clinical research has also shown that concentrations between 2% and 5% are effective for improving skin barrier function, while higher concentrations may provide additional benefits for oily and acne-prone skin when properly formulated.

Niacinamide is considered safe for daily cosmetic use and is well tolerated by most skin types. It is suitable for sensitive skin and can be used during both morning and evening skincare routines.

Although uncommon, mild irritation may occur in individuals with highly sensitive skin when using high concentrations. A patch test is recommended before introducing any new skincare product into a routine.
