After collagen and hyaluronic acid, will it be the next strong oral beauty ingredient?

With the rise of the concept of “same food and makeup”, collagen and hyaluronic acid have become star ingredients in oral beauty functional foods, while another important beauty ingredient, niacinamide, has been less popular in recent years.

What is niacinamide?

Nicotinamide, an amide related to niacin, belongs to vitamin B3. Niacin is a water-soluble vitamin that can be converted into nicotinamide in the human body. Niacin and niacinamide have similar functions. Niacin is a colorless needle-like crystal, and the niacinamide crystal is a white powder with stronger solubility than niacin.

In terms of physiological functions, nicotinamide, as a component of Coenzyme I and coenzyme II, participates in lipid metabolism in the body, the oxidation process of tissue respiration, and the process of anaerobic decomposition of carbohydrates. It is mainly used clinically for pellagra, stomatitis, and deficiency. Blood heart disease, thrombotic obstructive disease, etc. In the field of cosmetics, niacinamide is an extremely commonly used star ingredient, which can be used for moisturizing, whitening, acne, anti-wrinkle and sunscreen. Among them, whitening is the most well-known function of niacinamide. In an experiment with Japanese women as research subjects, niacinamide emulsion with a concentration of 5% and sunscreen products containing 2% niacinamide were used respectively. After comparison with blank experiments and computer data analysis, the results show that niacinamide has inhibitory effects. Melanin transfers from melanocytes to keratinocytes. At the same time, nicotinamide can accelerate the shedding of melanin-containing cells in the epidermis because it promotes skin metabolism. Although it cannot fundamentally control the production of melanin, it can intervene and reduce the deposition of melanin, and play a role in whitening.

So, does oral nicotinamide have the same whitening effect? Studies have confirmed that nicotinamide can prevent the transport of melanin in the body to keratinocytes, and at the same time can promote the body's metabolism to accelerate the decomposition of melanin in the body and hinder the transport of melanin particles to the keratinocytes of the skin. However, the whitening effect of niacinamide can only be an auxiliary means, and the most important way of whitening is sun protection. In addition, oral nicotinamide can help fight dermatitis, increase skin moisture, improve skin barrier function, reduce photo-aging, and promote muscle Collagen production. Moreover, as a water-soluble vitamin, nicotinamide can be completely absorbed by oral administration.
