Ceramides are lipids that the skin itself can synthesize, the molecule is much larger than niacinamide, the latest research shows that it has the role of cell information transmission, can regulate cell differentiation, value-added and apoptosis.
It is an important part of the stratum corneum of the epidermis, and its greatest role is to prevent moisture from being excessively dispersed from the skin. In cosmetics, its main role is to moisturize, relieve allergy symptoms, and repair the skin barrier function.
Then niacinamide is niacin (vitamin) amide, which is also a member of the water-soluble vitamin B family. In cosmetics, the role of niacinamide is to reduce acne after the formation of melanin, improve skin moisture retention, reduce wrinkles, whitening, such as SK-II's small silver bottle whitening essence, which contains a large number of niacinamide ingredients. Of course, let's explain here, this is not a recommended product, SK-II did not give us advertising fees.
I hope the above content can provide you with a little help.
