1. Skin lightening benefits

According to thousands of researches, Niacinamide was proved can inhibit the transfer of melanin from melanocytes to keratinocytes, a key step in providing a fair skin tone. Niacinamide was demonstrated to provide pigmentation benefits by imparting an overall brighter skin tone and reduction of age spots. Niacinamide could also be considered to reduce post-inflammatory hyperpigmentation (PIH) observed in acne pathology.

2. Improving appearance of aging skin

Skin ageing is characterised by major skin changes, like reduced skin elasticity, poorer structure and appearance of wrinkles. An important factor is the gradual breakdown and loss of collagen and elastin fibres. A substance to counteract such degradation would also slow down skin ageing. In vitro tests with human fibroblasts from aged donors that were cultivated with niacinamide showed that niacinamide stimulates new fibroblasts by 20% and collagen secretion by 54%.

3. Barrier strengthening properties

Skin softness, suppleness and skin hydration are related to the barrier properties of the horny layer. It is known that several lipids such as fatty acids and ceramides are critical for the structural and functional integrity of the stratum corneum. A study conducted by Tanno showed that topical application of 2% niacinamide reduced the TEWL by 27% in four weeks. At the same time free fatty acids and ceramides in the stratum corneum were boosted by 67% and 34%, respectively.
