Niacinamide is a whitening ingredient, but it does not work for some people, what are the factors?

Niacinamide is a whitening ingredient, but it does not work for some people, which may be caused by the concentration of niacinamide, the time it is used, and the environmentWhen it comes to niacinamide, I think everyone must be familiar with it, especially for women, because women love beauty and always like to buy a variety of skin care products, and skin care products containing niacinamide can now be said to be very popular, because the whitening effect of niacinamide is very good, and therefore it is respected by everyone.

First of all, niacinamide has no effect on melasma, niacinamide is mainly used to brighten the skin tone, and the use of any skin care products must be insisted on, not insisting is definitely ineffective, no skin care products can only rub for one day or two will produce results, the normal metabolic cycle is 28 days, so we usually insist on 28 days before we can see the effect, skin care should not give up halfway,theThe second is the concentration of niacinamide, generally the concentration of niacinamide with whitening effect is about 2% 3%, if the concentration is less than 2%, it will not have much effect.

And everyone's skin type is different, so the suitable concentration is also different, if you use a concentration of 2% niacinamide has no effect, then it is recommended that you can try a concentration of 3% niacinamide, followed by niacinamide is very afraid of light,Niacinamide will not only make us white, but will make us black, so when using niacinamide, we must avoid light, it is best to use it at night, if you have to use it during the day, you must remember to protect from the sun, otherwise it is likely to become darker than before.

The above is the reason why some people don't work with niacinamide, in fact, niacinamide itself has no problems, and niacinamide can not only whiten, but also antioxidant, which is a very good becomingIf you use it and it doesn't work, you can compare what I said above to see if you're wrong.

It may be that there are some substances in the human body that oppose this substance, and there are some substances in the body that will react with this kind of thing and make it ineffective, so it cannot play any role.

The reason for this is that everyone's physique is different, and some people really don't have an effect on a certain ingredient.

The reason why it doesn't work for some people may be because they are intolerant to this ingredient, which may be caused by skin factors.

Niacinamide can be whitened!

Niacinamide increases the production of energy within cells, in other words, making it more energetic. Niacinamide is formed when we eat foods that contain high niacin, such as animal liver or mushrooms. We convert niacin into active nicotinamide, which in turn acts as a precursor to the coenzymes NADH and NADPH.

One of the key roles of coenzymes mentioned here is to promote cell metabolism, which means that our problems can be repaired faster, and the sub-health of the skin caused by slow metabolism such as dull skin tone can also be improved. Another piece of good news is that niacinyl gum, which can be obtained through the daily diet, can also be used topically to use products containing niacinamide, all of which allow ** to absorb nutrients.

However, I would like to remind those who are using niacinamide skincare products that niacinamide can work with melanosomes that lower melanocytes to keratinocytes, reducing the amount of melanin transferred to surface cells. That's why long-term use of niacinamide can whiten.

Niacinamide is able to whiten, and this ingredient whitens more than we think, and the effect is very good.

1.Whitening. Nicotinamide can speed up metabolism and speed up the shedding of keratinocytes.

Nicotinamide has a small molecular weight and can be directly absorbed by epidermal cells, stimulate the vitality of some cells that have declined, promote collagen synthesis, prevent excessive deposition of melanin, and achieve the effect of whitening.

2.Control oil and reduce pores.

When the content of niacinamide in skin care products reaches 2%, it can reduce the production of fatty acids and triglycerides in the secreted sebum, achieve the effect of controlling oil secretion, reduce oil secretion, and make the pores, the channel for secretion of sebum, gradually shrink, so as to achieve the purpose of shrinking pores. The reason is that niacinamide can downregulate the melanosome transport of melanocytes to keratinocytes without inhibiting tyrosinase activity or cell proliferation, thereby affecting pigmentation.

It can also interfere with the cell signaling pathway between keratinocytes and melanocytes, reducing melanin production. Obviously, the effect depends on whether the ingredients are enough, and it usually takes one or two months for the whitening effect to appear.

Niacinamide will have a certain effect on whitening. Because niacinamide interferes with melanin production, when melanin gradually decreases, the whitening effect can be achieved. However, whether the whitening effect is obvious or depends on the composition of niacinamide, it generally takes about one to two months to see the whitening effect.

Whitening.

Because of the traditional beauty concept of "one white covering three ugliness", women have a persistent pursuit of whitening. There are all kinds of whitening products and whitening methods, please judge carefully and choose the right whitening method. Whitening and moisturizing should follow nature, and the amount of pigment contained in each person's ** is determined by genetics.

There are two types of UV damage to **: one is immediate damage – sun burn and tanning; The other is long-term damage – sun spots and pigmentation, fine lines and wrinkles appear, which can lead to cancer.

Niacinamide does have a whitening effect, nicotinamide can down-regulate the transport of melanosomes from melanocytes to keratinocytes, without inhibiting tyrosinase activity or cell proliferation, thereby affecting **pigmentation, it can also interfere with the cell signaling channel between keratinocytes and melanocytes, reducing melanin production.

Niacinamide does have a whitening effect. Nicotinamide can downregulate the transport of melanosomes from melanocytes to keratinocytes without inhibiting tyrosinase activity or cell proliferation, thereby affecting hyperpigmentation. It can also interfere with the horn cell signaling pathway between melanocytes and melanocytes, reducing melanin production.

Niacinamide is a water-soluble vitamin B group member is a derivative of vitamin B three, which can inhibit inflammatory cytokines, enhance the barrier function, maintain the water of the first class, and has a good antioxidant effect, first of all, it is a classic anti-aging and beauty ingredient, and some have significantly inhibited the transfer of melanocytes to epidermal cells.

Niacinamide can indeed whiten, but niacinamide needs to be commonly used, and it will take several months to have a whitening effect.

Niacinamide can really whiten because the function of niacinamide is to block the transmission of melanin.

Yes. Because niacinamide can slow down the movement of melanin, and it can accelerate the metabolism of melanin, it can really whiten.

Can niacinamide really whiten? What are the main benefits? What skin is it suitable for?

Niacinamide is a form of vitamin B3, also called niacin or niacin. This substance does have a whitening function.

Niacinamide is often added to skincare products because of its ability to improve** pigmentation. Specifically, niacinamide can regulate and reduce the production of pigment in **, thereby reducing the accumulation of melanin and alleviating the dullness of **. It also stimulates cell renewal in the basal layer, making the skin smoother and more refined.

It is worth mentioning that niacinamide can also improve problems such as erythema and acne, and alleviate discomfort.

In addition, niacinamide also has an antioxidant effect, which can reduce the damage of free radicals to ** and help slow down the process of skin aging. It also enhances the function of the barrier, reduces water loss, and retains water and nutrients.

Overall, the efficacy of niacinamide in whitening skin care is well established. However, it is important to note that niacinamide may have different effects for people with different skin types or different ways of using it. In addition, if there is a serious pigmentation problem, the use of niacinamide cannot completely solve the problem, and it also needs to be combined with other whitening ingredients or methods.

Therefore, before using niacinamide products, it is advisable to understand your skin type and purpose, and pay attention to extra moisturizing during use. <>
