Can niacinamide powder be applied externally for whitening?

*Niacinamide powder can be applied externally to whiten**. Niacinamide powder can effectively inhibit the formation of melanin after being applied to the face, thus having a whitening effect.

The largest in the skin care industry** Adding the ace ingredient niacinamide will definitely whiten?

Niacinamide is used correctly.

When using niacinamide, like serum, take an appropriate amount of essence and apply it to the face after cleansing, or add it to skin care products such as creams and shower gels. Niacinamide can effectively inhibit the formation of melanin, and can block the accumulation and transfer of melanin in **, so as to achieve the effect of whitening skin and improving pigmentation. The use of niacinamide can increase and repair the skin's barrier function and reduce the phenomenon of pigmentation and erythema caused by photoaging.

Niacinamide can inhibit the reaction of glucose synthesis lipid and inhibit the secretion of sebum by sebaceous glands, so it also has the effect of controlling oil and refining pores. Niacinamide is a substance that can also be used for acne, and niacinamide is added to many acne products. Niacinamide can be tolerated, for some ** more sensitive people, you can gradually eliminate the discomfort after a few uses, but if you are allergic to a certain ingredient in the product, the phenomenon of allergies will not stop, allergies are a problem with the body's mechanism, it is best to stop using.

Start with a product with a lower concentration, or you can apply a little behind the ear and use it if there is no noticeable discomfort. Niacinamide is suitable for all skin types, and for dry**, niacinamide has the effect of repairing the skin barrier, which can effectively improve the skin's ability to retain moisture. For oiliness**, it has the effect of controlling oil and refining pores.

Niacinamide can be used directly after cleansing the face, and it can also be flexibly matched, and you can make a whitening water film with toner, shrinking pores and blackening at the same time, and when paired with body lotion, the whole body can be white to glow.

Niacinamide can indeed turn white, because it inhibits melanin, but melanin will not disappear, it will accelerate the accumulation, if you eat it for a long time, you will be envious once you guess that if you don't eat it, Suikai will turn black, and if you don't eat it for 7 consecutive days, you may become black.

Niacinamide can be whitened.

Niacinamide can be whitened, but it can only play an auxiliary effect on whitening, not completely, and it needs to be used for a long time. The appearance of darkening is mainly due to excessive precipitation of melanin, or it can be caused by improper care for a long time or dehydration.

Niacinamide can be directly applied to the epidermal layer, which can inhibit the precipitation of local melanin, make the local melanin whiten quickly, and can also promote the metabolism of the local stratum corneum, but the effect is not particularly obvious.

Whitening tips:

1. Milk whitening method.

The most commonly used daily whitening tips are the milk whitening method, first you need to prepare an appropriate amount of milk, then put the milk in the refrigerator for about 10 minutes, then take out the cotton pad and soak it in the milk, then apply it to the face for 15 minutes, and then wash it off. This method is used 1 2 times a day for a week to achieve significant whitening.

2. White vinegar face washing method.

White vinegar can well inhibit the production of melanin on the face, and the whitening effect is very good, but the mixing ratio of water and white vinegar must be carefully controlled, so as to make the whitening effect more ideal.

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 can be whitened. Nicotinamide can downregulate melanosome transport from melanocytes to keratinocytes without inhibiting tyrosinase activity or cell proliferation, thereby affecting hyperpigmentation, and it can also interfere with the cell signaling channel between keratinocytes and melanocytes to reduce melanin production. Therefore, theoretically, it can reduce the production of melanin and thus play a whitening role.

However, babies with sensitive skin and red blood should not use it.

Precautions for the use of niacinamideNiacinamide and A alcohol go well together. For oily skin, both regulate sebum production, and A-alcohol also has the effect of accelerating epidermal renewal. At the same time, it is also a plus for the effect on the fine pores.

In terms of whitening and anti-aging, in addition to the whitening of niacinamide, A-alcohol also has the effect of promoting collagen synthesis. Therefore, the effect of using these 2 ingredients at the same time should be better.

Niacinamide can be hydrolyzed into niacin under acidic and alkaline conditions, so if it is a high-content VC product, if the pH value is very low, it may react with a high concentration of nicotinamide to produce a weak niacin, but fortunately, the process is extremely slow, so the amount generated is very small, and it may even be too small for many people to finish and do not feel, pay attention to apply the product for a short period of time.
