What Is Niacinamide? Skin Benefits & Products in South Africa

Niacinamide, also called nicotinamide, is a form of vitamin B3 used in topical skincare. Human studies have tested specific niacinamide formulas for skin-barrier support, visible pigmentation, facial sebum and signs of photoaged skin. Results depend on the complete formula and the person using it; one study does not prove that every niacinamide product performs the same way.

What does niacinamide do for skin?

Skin barrier and hydration

In a left-right study of 28 people with atopic dry skin, a cream containing 2% nicotinamide reduced transepidermal water loss and increased skin hydration over four or eight weeks. Read the PubMed study.

Visible pigmentation and uneven-looking tone

A randomized study reported that topical niacinamide reduced visible hyperpigmentation compared with the vehicle after four weeks. Read the PubMed study. A separate 12-week, split-face study of 50 women found that a moisturiser containing 5% niacinamide improved hyperpigmented spots, texture and red blotchiness compared with the control formula. Read the PubMed study.

Facial oil

Clinical trials using a moisturiser containing 2% niacinamide found reductions in measured facial sebum, although the specific outcome differed between the Japanese and Caucasian study groups. Read the PubMed study.

How to use a niacinamide skincare product

Follow the directions for the exact serum, moisturiser, toner or other product you choose. The studies above tested concentrations from 2% to 5% in specific formulas and protocols; they do not establish that the highest available percentage is best. Introduce one new product at a time, and stop using it if irritation persists.

How long does niacinamide take to show results?

The cited studies assessed outcomes after four to twelve weeks, depending on the formula and outcome. That is research context, not a guaranteed timeline for every product or person.
