What are the common forms of nicotinamide?

Nicotinamide is an ingredient that can be used externally and internally, but you should check which method is appropriate before using it. It is recommended that adults consume no more than 20 mg of nicotinamide per day. Excessive use of nicotinamide will not increase the use effect, because it is not fully absorbed, but causes a burden on the human body and affects normal function.

Topical nicotinamide is a very common one that can be added to lotions, creams, serums, sunscreens, and other products. Nicotinamide added in such products is generally cosmetic grade nicotinamide, in the form of powder, tablet, etc., but it is not recommended to add nicotinamide in skin care products, why? This is because we can not control the dose and concentration of nicotinamide, this simple and crude addition, is not conducive to the play of the nicotinamide effect, even counterproductive. If you want to use nicotinamide in your skin care products, we still recommend that you purchase products containing nicotinamide through legal channels.
