Skin is itching due to Niacinamide

Which niacimide serum did you use? Some people cannot tolerate more than 5% Niacinamide serum because it causes contact dermatitis

Itching is usually irritation from allergy 😕

I would definitely stop using

Itching is maybe because of some type of allergy

Which niacinamide product are you using, and what’s the concentration? • It could be the concentration. • It could be skin sensitivity from underlying conditions like rosacea or eczema. • It could be other ingredients in the product, like fragrance. • It might be an initial reaction or a rare allergy. If the itching persists, consult a dermatologist. Try not to scratch your skin. 🫶
