Niacinamide can be said to be the most popular skin care ingredients in recent years, there is no one, many whitening, anti-aging skin care products contain niacinamide ingredients, with the use of more and more niacinamide products, but also caused a lot of problems, today to summarize some of the problems that everyone is more concerned about in the process of using niacinamide, let's take a look at it with me.
Niacinamide is also called vitamin B3, and there are also complex names such as vitamin PP, 3-pyridinecarboxamide, niacinamide, and niacinamide. The English name is Nicotinamide, also known as 3-Pyridinecarboxamide, when you see these two words, it means that this is niacinamide or the product contains niacinamide ingredients.
The application technology of niacinamide in skin care products has been very mature. Its role is most commonly whitening, and its whitening mechanism mainly contains the following aspects: one is to accelerate metabolism and promote the shedding of melanin-containing keratin cells; the other is to act on the melanin that has been produced, reducing its transfer to surface cells;
In addition, niacinamide can promote the synthesis of proteins in the epidermis, enhance the skin's own defense ability, and increase the skin moisture content. Promotes the synthesis of epidermal proteins and improves skin texture, so niacinamide is also widely used in anti-aging products.
Intolerance is when a small number of people may have problems with redness or tingling of the skin. Disadvantages of niacinamide as a whitening product: Niacinamide is intolerant. Everything has pros and cons, niacinamide also has its shortcomings, the most important point is that the impurity component niacin in its raw materials will cause skin irritation, and some consumers may use high content of niacinamide products may cause redness and other allergies. That is, the problem of niacinamide intolerance that everyone likes to talk about.
However, the problem of tolerance to niacinamide cannot be generalized, not everyone is intolerant to it, and the problem of tolerance can be slowly established later. Ordinary people can slowly establish tolerance from a lower concentration of niacinamide, which can be applied in about one to two weeks, but if the skin still feels uncomfortable after a period of time, it can only mean that the skin type is not suitable for this ingredient and cannot be established.
Niacinamide has no photosensitivity, is not afraid of light and heat, and niacinamide also has anti-blue light effect, which can be used during the day.
The combination of niacinamide and A alcohol is good. For oily skin, both regulate sebum secretion, and Aol also has the effect of accelerating epidermal renewal. At the same time, the effect on the detail of pores is also a bonus. 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.
Some people say that after using niacinamide, the pores become darker and more obvious, first of all, the probability is very low, anyway, I ran out of it myself, there is no such situation at all. So why is it happening?
It may be that niacinamide brightens your skin tone, so it makes your hair look more pronounced.
It may also be because niacinamide can promote capillary circulation, and the nutrition of the hair is better, so it may grow a little more vigorously. But there is no literature or data to confirm that niacinamide can really promote hair growth.
Even if the hair really turns black, from everyone's feedback, it will slowly recover after a few months of deactivation, so don't worry too much about this aspect.
Question 7: What ingredients can niacinamide not be combined with?
This is mainly some high concentration, note that I am talking about a high concentration of vitamin C, salicylic acid, and fruit acid this product. Because of such a product, usually its PH value will be relatively low, and the acidity is relatively strong.
In this case, niacinamide may produce a small amount of niacin as an impurity, so if you want to use it with these products, you can use it slightly at intervals, such as 10 minutes, or use one in the morning and another in the evening, which is definitely a safer way.
The above is some of the problems that need to be paid attention to in the use of niacinamide, and I hope to bring help to everyone!
