Why is it not effective to use nicotinamide?

Niacinamide is not a panacea, of course it doesn't work.

Actually, it's B vitamins, okay?

You spend a few bucks on a bottle of vitamin B3, take out one and dissolve it, which is higher than the nicotinamide content of your bottle.

Don't blindly worship a series of terms such as niacinamide and squalene, which are actually very cheap chemical raw materials.

Niacinamide is actually vitamin B3, just a kind of B vitamins, there is no need to mythologize it, and there is no need to exaggerate the efficacy of niacinamide, consumers should also correctly understand and use nicotinamide-containing products. The effect of nicotinamide in blocking the transfer of melanosomes to keratinocytes is beyond expectations, which has a certain effect on whitening, but it should not be the most important effect. From the point of view of the steps in melanocytes in which tyrosine is synthesized, generated, secreted, and transported to keratinocytes by tyrosinase, transport is a part.

If the melanocytes are activated after ultraviolet exposure and synthesize a large amount of melanin, then the melanocytes are filled with melanosomes, which will definitely be secreted, although they cannot enter the keratinocytes, then they will also be scattered in the intercellular interstitium, or down into the dermis. Therefore, the whitening function of niacinamide is limited. If you do not inhibit tyrosinase activity, do not block ultraviolet rays (including blue light), do not control inflammation, and rely only on niacinamide, whitening is not easy to do.

The main reason for the use of niacinamide products is that everyone's skin is different, and your skin type is also different. Coupled with daily living habits, it can be effective when combined.

Although niacinamide products have the effect of removing melanin and whitening, this product is not suitable for anyone, and improper application may also produce ***, when using it, it must be applied two or three times behind the ear without allergies and other conditions to be used normally, and there is no effect after normal use, which may be due to the rapid production of melanin in the body, or the use method is not equal, and it is possible to buy fake and shoddy products, you can go to the product store to check and confirm.

That's because you use it yourself, it doesn't work, or you feel that it doesn't work, this cosmetics are all personal, according to your personal ** personal habits of ingestion things. It has a lot to do with that, so to speak. Some of these things are not suitable for you, but not necessarily for others.

Because everyone's skin type is different, niacinamide products are not suitable for everyone, that is to say, no one uses it, there will be an effect that suits you is the best. You can choose to try something else.

Niacinamide has a whitening effect at an effective concentration of 2% 3%, which is the mass concentration, which is different for each person's constitution, and may be higher or lower. If your product is 3% niacinamide, you may need a niacinamide concentration higher than 3% for it to work, it is recommended to try a 4% concentration.

Since you are using a body lotion instead of an essence, there are some body lotions on the market that only have the concept of niacinamide, and the product says that it is niacinamide body lotion, which makes you white into a light, makes you sparkle or something, and the amount added is in between. You don't even think about it when you're done.

Assuming the product you use is conscientious, the single whitening effect of niacinamide will take more than 2 months. Niacinamide is a very good whitening agent, mainly because it is cheap, the mechanism is different from that of conventional whitening agents, and the synergistic effect with other whitening agents is very good, but the single use is very general, and the whitening effect is normal after 2 to 3 months. If you're only a month, the effect may not be noticeable.

Maybe you don't wait for your body to dry after taking a bath and apply niacinamide, at this time there is still water on your body, which is equivalent to diluting the body lotion that is not high in concentration, and the concentration of niacinamide is lower, which affects the penetration of niacinamide.

Have you used some film-forming moisturizing ingredients before using niacinamide, such as xanthan gum, carbomer, cellulose, aloe vera gel, etc. in the toner, and then using niacinamide after using these will reduce the effect of subsequent niacinamide.

Your sunscreen may not be in place, and your sweaty body hates the feeling of stickiness more than that of your face, so you generally don't apply enough sunscreen on your body, and if you don't apply enough, the effect will be reduced. It is recommended that if you really want to whiten, long clothes and trousers are better.

If the above problems have been hit, it is recommended to adjust the product or use method, if none of the above, although there are other reasons, but I think it may be better for you to change the product at this time.

Many people who have used niacinamide have no effect and even have negative effects may be due to the following reasons. 1. Content problem. Many people use niacinamide products that only pretend to have niacinamide ingredients, but in fact, they are only marked on the packaging to attract purchases, and the content is very small; The second is the problem of intolerance caused by excessive content, so don't pursue high content too much, it needs to be a gradual adaptation process.
