What is the reaction to niacinamide stock solution intolerance? Why is niacinamide intolerance

Anyone who knows a little about whitening products has heard of a whitening ingredient - vitamin B3 (niacinamide). Although it has a good whitening effect, it is not suitable for everyone. Some people are intolerant to it. So, what is the reaction of niacinamide stock solution intolerance?

What is the reaction to niacinamide intolerance?

The main reaction to intolerance to niacinamide concentrate is allergic symptoms such as skin redness, stinging, and itching. Niacinamide contains a certain amount of niacin, which is an allergen. People with sensitive skin or allergic constitution are prone to intolerance, which will cause such reactions.

Why is niacinamide intolerant?

The reason why niacinamide intolerance occurs is mainly because niacinamide contains extremely small amounts of niacin. Therefore, when choosing products containing niacinamide, you must pay attention to the purity of niacinamide. The higher the purity, the lower the niacin content. In general, niacinamide is most stable in a solution with a pH of 6. In solutions with a pH above or below 6, it hydrolyzes to form niacin, which can cause skin irritation. Therefore, formulas containing niacinamide generally control the pH between 5 and 7 to reduce the formation of niacin. Therefore, when using products containing niacinamide, be careful not to mix them with products with an acidic pH.

What to do if you are intolerant to niacinamide stock solution

If your skin is intolerant to niacinamide, either give it up or build tolerance. If you experience niacinamide intolerance during use, you should stop using it immediately to avoid aggravating the discomfort and causing facial problems, or reduce the dosage to improve your skin's tolerance to niacin.

To build tolerance to niacinamide stock solution, you need to start with low concentrations of niacinamide. Before applying it on your face, perform an allergy test on delicate areas such as behind your ears and inside your wrists. Make sure you are not allergic before applying it on your face. During subsequent use, gradually increase the concentration of niacinamide from low to high concentrations, from local skin to full facial skin, and from less use to more use, so that your skin can gradually adapt and build up tolerance.

How to determine niacinamide intolerance

Check for any discomfort. Common adverse reactions to niacinamide include redness, itching, peeling and other symptoms. If these problems occur on the skin while using niacinamide products, stop using them immediately. It may be that tolerance was not established before use. Wait until the skin condition improves before establishing tolerance.
