Most people know that nicotinamide has a very good whitening and brightening effect, but some people report that they are allergic after using niacinamide products. There are the following precautions when using nicotinamide.
Before understanding the precautions of niacinamide, let’s first understand the advantages of nicotinamide.
- Whitening and brightening
Whitening and brightening is the greatest effect of nicotinamide products. Nicotinamide can well inhibit the growth and transfer of melanin, and then play a role in reducing dark spots and dullness. And it can also promote the skin’s metabolism and accelerate the decomposition of melanin, thereby playing a very good whitening and brightening effect.
- Anti-acne and oil control
This effect may be known to fewer people. Previous clinical trials have shown that external use of 2% niacinamide has a certain effect on controlling the secretion of skin oil, and it can also eliminate various skin inflammations that cause by acne.
- Anti-aging and repair skin barrier
In addition to the whitening effect of nicotinamide, the most obvious effect is anti-aging effect. Nicotinamide can well promote the metabolism of the skin, and it can also promote the micro-circulation of the dermis layer and promote the synthesis of epidermal protein. Moreover, niacinamide can reduce the damage of free radicals to the skin. Many anti-aging skin care products contain nicotinamide.
Although nicotinamide has good effect, there are also some important precautions when using it. It it is used improperly, it may not only have no effect, but it may also be counterproductive. Let’s take a look at the precautions for using niacinamide.
- Choose the right concentration
The concentration of nicotinamide added in different products will also be different. If you just want to moisturize and repair the skin barrier, you can choose to add 2% nicotinamide, but if you want to achieve a whitening effect, you need to add a 3% concentration of niacinamide products.
5% concentration of niacinamide is added to the common whitening essences on the market. For most people, 5% concentration of niacinamide is a relatively mild concentration, but if it exceeds 5%, it may be irritating for some people.
- Build skin tolerance
For people who are trying niacinamide for the first time, building tolerance is a necessary process. It is recommended that everyone start with a low concentration and build skin tolerance step by step.
- Do not use nicotinamide with acid products
When using nicotinamide, do not use it in combination with acid products, because niacinamide will turn into niacin at low PH, and niacin has a certain irritation to our skin. Therefore, if niacinamide is used together with acids, not only will it not have the whitening effect, but there will be serious consequences.
- Try not to use it during the day
Someone may have heard that niacinamide cannot be used during the day. It is not impossible to use it during the day, but pay attention to the concentration of niacinamide. High-concentration niacinamide used during the day may weaken the skin’s resistance and make the skin susceptible to external irritation.
After reading the above content, I believe that everyone has a certain understanding of niacinamide. Whitening is not a matter of overnight. You should choose the method and product that suits you according to your skin type.
