Nicotinamide is a derivative of vitamin B3, also called vitamin pp, and a member of the vitamin family. After years of scientific research, its safety and effect are being affirmed by more and more companies. It has high whitening safety and multiple skin care effects, and is recognized as an anti-aging ingredient in the field of cosmetic dermatology. In medicine, it can also be used for skin diseases such as pellagra, stomatitis, liver diseases and solar dermatitis.

The function of nicotinamide:

1. Whitening and light spots:

Nicotinamide can effectively inhibit the formation of melanin, and can block the transfer of melanin to the stratum corneum, thus achieving the effect of whitening skin. Nicotinamide is also used to improve pigmentation, which can reduce melanin that has been generated and precipitated, block its transfer to surface cells, accelerate cell metabolism and accelerate the shedding of melanin keratinocytes.

2. Anti-aging:

Nicotinamide can promote the synthesis of epidermal protein, improve skin texture, reduce or eliminate skin aging phenomena, such as wrinkles, peeling, large pores, etc., reduce the damage of free radicals to the skin, and play a role in preventing aging, repairing skin and reducing facial dullness.

3. Control oil and fine pores:

Large pores are one of the skin problems of many people. Topical nicotinamide can reduce the production of fatty acids and triglycerides in sebum, thus inhibiting sebum secretion by sebaceous glands, narrowing pores and reducing the severity of acne. That is, it has the function of controlling oil and fine pores.

4. Repairing the barrier, moisturizing and moisturizing

Nicotinamide has a good repairing effect, at the same time, it can maintain the skin moisture content, promote the microcirculation of the dermis, increase the synthesis of keratin, increase the level of free ceramide in the skin, reduce the transdermal water loss and repair the barrier function of the skin.

Nicotinamide also has its shortcomings. The most important point is that nicotinic acid, an impurity component in its raw materials, can cause skin irritation. Therefore, nicotinamide used in cosmetics should pay attention to the control of raw materials or impurities, and both formula design and technology have an impact on it. Some people may be using products with high content of nicotinamide, which may cause allergic phenomena such as redness, that is, nicotinamide intolerance. If you want to continue to use it, you need to gradually establish tolerance. When using it, you should start with a low concentration or a small amount, and gradually increase it to a normal amount with the change of skin condition.

In recent years, people have paid more and more attention to nicotinamide. There are more and more skin care products containing nicotinamide, including essence, cream, mask and even shower gel, and even nicotinamide stock solution. Here are a few skin care products I have used for everyone.

1. Olay white bottle

99% purity, 5% concentration of nicotinamide, gold concentration ratio and other skin care factors reduce melanin aggregation, and nicotinamide is more tolerant, and the skin color is obviously brightened and uniform after use.

2、The? Ordinary? 1%? The concentration of nicotinamide essence

1% is not recommended for novices. It has good efficacy and oil control ability, and is suitable for acne muscles, but only if nicotinamide is tolerant. The disadvantage is that it smells like glue, and the gel-like texture is sticky.

3. SKII light bulb

The concentration of nicotinamide is 5%, which absorbs quickly. The special feature is that it contains pitera, which can whiten the skin and nourish the skin at the same time. Of course, the disadvantage is that it is expensive.
