There are many benefits of vitamin B3 that has been discovered through the years. Studies have proven in the recent years that vitamin B3 is a powerful ingredient that yields many skin care benefits. It has been proven effective both in oral use as supplement and in topical use. It has anti-inflammatory properties, helps to keep the skin pores open and protects the skin from UV damage caused by the sun.
Commonly known as Vitamin B3, Niacinamide at 2% has been shown to reduce water loss in the skin and retain fatty acid levels (younger, plumper, firmer skin). It has also been proven at high concentrations (between 3-4%) to be a very effective acne reducer.
Vitamin B3 is also an excellent skin lightening agent that works by disrupting the transfer of melanosome from the melanocyte to the keratinocyte.
In general, most individuals saw results after 12 weeks of daily usage (and saw a reduction of 35-68% of pigmentation). Like with most other skin lightening compounds, vitamin B3 has an inhibitory effect and in order to get the most out of it, you must be wearing sunscreen everyday and exfoliate often to ensure a complete melanin inhibiting process.
Vitamin B3 is an effective treatment for acne.
It inhibits the inflammation, reduces acne scars, helps to keep skin pores open, protects the skin from UV damage and might even reduce sebum production.
