Niacinamide is a good skin care ingredient, which is added to many skin care products. Many people think it's good, but for sensitive skin people, it's not recommended to use it. Let's get to know.
Can nicotinamide be used in sensitive muscles
Intolerance is the biggest drawback of nicotinamide. Because nicotinamide has the best stability in the solution with pH value of 6, hydrolysis reaction will take place in the solution with pH value greater than or less than 6, forming nicotinic acid. The pharmacology and toxicity of niacin are higher than niacinamide. It's this niacin that causes allergic reactions in some people. Including skin redness, itching, tingling, acne and other symptoms, and these symptoms are more likely to occur in cold and dry climate. Therefore, don't use nicotinamide products with high concentration at random depending on your skin thickness in the past. You must start from low concentration product spot application and try it step by step. After two or three days of test period and establishment of tolerance, you can try nicotinamide products normally. Otherwise, it will be very painful if you don't tolerate it. Moreover, you should correct and emphasize one point of view: the intolerance of nicotinamide It is not directly related to whether it is a sensitive muscle or not. The implication is that even if your skin is thin and sensitive, you may be resistant to niacinamide without allergic reaction; otherwise, if your skin is thick or not sensitive, you may also be intolerant to Niacinamide, or even have various allergic phenomena (but people with red blood shreds are more likely to be intolerant than ordinary people, so it is suggested that sensitive muscles should not be used easily).
How can sensitive muscles use niacinamide
Although nicotinamide is good, it can't be greedy! Nicotinamide is similar to vitamin C, the higher the concentration, the greater the skin irritation! Sensitive skin is not suitable for higher concentration, such as 5% nicotinamide products, which will produce stinging, itching, red skin and other intolerable phenomena, at this time, it should be stopped immediately. The so-called "gradually build tolerance" is not scientific! Sensitive muscle patients or patients with red blood should solve skin problems through medical means before trying to use nicotinamide products. In addition, nicotinamide will hydrolyze to nicotinic acid under unstable conditions. Nicotinic acid has strong irritation to skin. Therefore, nicotinamide products must not be used together with acid products, such as ascorbic acid (VC), AHA fruit acid, ferulic acid, mandelic acid, salicylic acid, azelaic acid & hellip; & hellip;
