Identity & coverage details

Official CosIng inventory context recorded; chemical identity and the complete current regulatory profile remain unverified; selected human studies available.

Recorded presence is not a safety rating, recommended dose or benefit claim.

Identity and formulation context

Names are indexed using case and whitespace normalization. Botanical, chemical and marketing identities have not been independently equated.

The 2% and 5% trials addressed different endpoints and formulations. Their concentrations are research conditions, not recommended doses.

How this inventory match is used

The European Commission’s CosIng inventory is informational. An entry is not permission to use an ingredient or a safety assessment. Listed functions describe the inventory entry; they do not establish a finished product’s effects. The match uses the exact ingredient name, with case and whitespace normalization.

Niacinamide: A B vitamin that improves aging facial skin appearance

2005 · Original abstract reviewed

Material tested: Niacinamide in a 5% preparation
Study design: Double-blind, randomized split-face comparison with vehicle.
Participants: 50 white women with visible facial photoaging.
Concentration and schedule in the study: 5% niacinamide preparation twice daily for 12 weeks.
What the authors reported: The authors reported improvements relative to vehicle in visible fine wrinkles, dark spots, redness, yellowing and measured elasticity.

What this does not establish

Restricted study population; results do not establish equivalent effects in all skin tones or ages.
The listed author affiliation is Procter & Gamble; this is one company-associated trial.
A 5% test preparation does not establish effects of different concentrations or finished products.

The effect of 2% niacinamide on facial sebum production

2006 · Original abstract reviewed

Material tested: Niacinamide in a 2% moisturizer
Study design: Two trials: balanced parallel groups in Japan and a randomized split-face comparison in the USA.
Participants: 100 Japanese participants (50 per group) and 30 white participants in the US trial.
Concentration and schedule in the study: 2% niacinamide moisturizer: four weeks in Japan; six weeks in the US trial. Frequency is not specified in the abstract.
What the authors reported: Sebum excretion fell in the Japanese trial at weeks two and four. In the US trial, surface sebum decreased at week six, while the excretion-rate reduction was not significant.

What this does not establish

Different sebum endpoints gave different results; this is not proof of acne treatment.
The abstract does not specify a complete application schedule.
The tested moisturizers have not been matched to products in this library.
