Why does my face hurt after applying niacinamide concentrate? It may be due to niacinamide intolerance

Niacinamide stock solution is a super effective skin care product that has been recommended by major internet celebrities recently. However, some people ask, why does it hurt to apply niacinamide stock solution on the face?

Why does it hurt to apply niacinamide solution on your face?

It could be niacinamide intolerance. Either the product is not suitable for your skin type, or it is your first time using it and you haven’t built up tolerance yet. The concentration of niacinamide stock solution is too high, and applying it on the face may cause skin effects such as acne and stinging. It is recommended to start with low concentrations, and then gradually choose higher concentrations after skin tolerance is established.

What skin types can’t use niacinamide stock solution?

It is recommended not to use on sensitive skin. Niacinamide is an irritating beauty ingredient. It will cause a tingling sensation on the face when used for the first time. It needs to be used in small doses, and then gradually increased in doses until tolerance is established. The skin barrier of sensitive skin is relatively fragile, and it is easy to produce allergic symptoms in the process of building tolerance. Therefore, it is recommended that sensitive skin should not use it.
