Skincare products generally contain a wide variety of well-known substances, each of which has advantages of its own. However, some substances should not be used in excessive concentrations because they may result in further skin issues. One such ingredient niacinamide is one of those.
Benefits of Niacinamide
Maintain a healthy skin barrier
Niacinamide can regulate epidermal ceramide synthesis on the epidermal skin barrier.
The structural and functional integrity of the skin barrier function is now known to be significantly influenced by ceramides. In aging skin, a decrease in ceramide fraction has been seen. According to studies, niacinamide may cause a 5-fold increase in ceramide production. By increasing the ceramides production, topical niacinamide appears to be able to improve the skin’s barrier functions and provide significant clinical advantages.
Stimulate New Collagen Synthesis
About 90% of the appearance of skin aging is caused by collagen loss in the skin, which is mostly caused by UV damage. Excessive sugar consumption and unhealthy lifestyle are also other factors that lower collagen levels. Studies show that niacinamide can increase collagen production and secretion. The increase in collagen leads the skin to appear significantly more plump and less wrinkled. These would be especially important for older and damaged skin.
Reduce Hyperpigmentation
Melanin is a pigment that skin cells produce that gives skin its color and Melanocytes, a type of skin cell, generate it. This cell may produce an excessive amount of melanin if they are harmed or unwell. This may results in the area appearing darker. Overproduction of melanin is a common factor in hyperpigmentation.
By lowering the amount of melanin in the skin and encouraging cell turnover, niacinamide can help to treat hyperpigmentation. A study was done and the results revealed an impressive increase in skin lightness after 4 weeks of treatment.
