What are the harmful effects of niacinamide on the skin

In order to make the skin white, smooth and delicate, people who love beauty will choose different skin care products. Many of these products contain niacinamide, which can speed up the skin's metabolism and make the skin delicate. But in addition to the good side, everyone should also understand the harm of niacinamide to the skin. Any product has two sides. The side effect of niacinamide is that it can easily cause skin allergies, so it should be used with caution.

Side effects of niacinamide on the skin

Everything has its pros and cons. Niacinamide also has its shortcomings. The most important point is that the impurity niacin in its raw materials can cause skin irritation. Some consumers may experience allergic reactions such as redness when using products with high niacinamide content. This is the niacinamide intolerance issue that everyone likes to talk about. Therefore, the use of niacinamide in cosmetics requires strict control of raw materials and impurities, and the formula design and process also have an impact on this. In this area, many companies have conducted more in-depth research and have launched a number of mature products.

1. Niacinamide causes skin redness

I don't want to repeat the explanation about redness, as many people have said it but I don't like to repeat it. In a nutshell, if you have sensitive skin or very dry skin, and the sebum membrane is not sound or the skin tolerance is not high enough, the irritation of niacinamide itself is likely to cause redness and allergies, or even...swelling.

The adults’ advice to sensitive girls is that before using niacinamide, try it on the back of your hand or behind your ear. If there is no redness, allergy or stinging, then use it on your face.

Also, don't try to do everything at once. The tolerance level of niacinamide needs to be built up little by little. You can try using 1%-2% concentration first, then add 1% after one week, 1% after two weeks, 1% after three weeks... and so on. Girls who don't want to buy various concentrations can first add the essence to the cream or lotion and mix them together.

2. Niacinamide stimulates the skin, promotes metabolism, and accelerates hair growth.

Normally, people cannot grow new hair follicles, which are the skin cells that make hair grow. All hair follicles are born with humans and accompany them throughout their lives. Hair follicles cannot regenerate after death. In other words, no matter how much niacinamide stimulates, there will be no new "pits" for the hair "carrot" to reproduce. In other words, your hair will only grow in the "pits" that you have had since birth, and the number will not increase.

One of the functions of niacinamide is to promote metabolism. That is to say, it can stimulate the metabolic rate of your epidermis, which can also promote hair growth. In other words, it's just that your original hair has been made a little taller by this "growth hormone"-like thing.
