Is there a lot of skin whitening ingredients in skin care products that can be used quickly? For sensitive skin people, Xiaobian is not recommended to use, let's get to know it.
Can sensitive muscle use nicotinamide
Intolerance is the biggest disadvantage of nicotinamide. The stability of nicotinamide is the best in the solution with pH value of 6, and the hydrolysis reaction will occur in the solution with pH value greater than or less than 6 to form nicotinic acid. The pharmacology and toxicity of nicotinic acid are higher than that of nicotinamide. It is this nicotinic acid that causes allergic reactions in some people. It includes skin redness, itching, tingling, acne and other symptoms, and these symptoms are more likely to occur in cold and dry climate conditions. Therefore, do not rely on their previous skin thickness on the random use of high concentration of nicotinamide products, must step by step from the low concentration of products point coating trial, after two or three days of testing period and establish tolerance, then normal trial nicotinamide products, otherwise, intolerance will be very painful yo! And, correct and emphasize a point of view: nicotinamide intolerance There is no direct relationship between the image and whether it is a sensitive muscle. The implication is that even if your skin is thin and easily allergic, it is possible to tolerate nicotinamide without allergic reaction; on the contrary, if you have thick skin and are not sensitive muscles, you may also be intolerant to nicotinamide and even have various allergic phenomena (but people with sensitive skin and red blood are more likely to have intolerance than ordinary people, so it is recommended that sensitive muscles should not be used easily).
How can sensitive muscle just use nicotinamide
Nicotinamide is good, but not too much! Nicotinamide and vitamin C are similar, the higher the concentration, the greater the skin irritation! More sensitive skin is not suitable for higher concentration, such as 5% nicotinamide products, will produce tingling, itching, skin reddening and other intolerable phenomenon, at this time should stop using immediately. The so-called "gradually establish tolerance," is not scientific! Patients with sensitive muscles or red blood should use nicotinamide products after solving skin problems through medical means. In addition, nicotinamide will hydrolyze to nicotinic acid under unstable conditions, and nicotinic acid has strong irritation to the skin. Therefore, nicotinamide products should never be used together with acid products, such as ascorbic acid (VC), AHA fruit acid, ferulic acid, mandelic acid, salicylic acid, azelaic acid & hellip;
