  Methyl niacin appears in the form of crystals or crystalline powder ranging from white to brown in appearance. When people observe carefully, they will find that it has a unique odor characteristic, which is a mixture of fresh scent, caramel-like sweetness, the rich flavor of nuts and a slight tobacco smell. This complex and unique odor makes it have a certain degree of recognition among many chemical substances. Methyl nicotinate is an irritating substance to human skin. When it comes into contact with human skin, it may cause uncomfortable reactions on the skin. Not only that, it also has a significant dilating effect on blood vessels, enabling them to expand to a certain extent. In terms of practical application, the main purpose of methyl nicotinate is to be used as a "red additive". When applied to the skin, it will cause redness, swelling or inflammation in the skin within a short period of time. Based on this characteristic, it is often used in lip augmentation or ot...
