Niacinamide and citric acid: depends on the strength

Depends on the strength

Apply them at different times of day, using the acid first and niacinamide later, because mixing them can cause redness and irritation. Citric acid is very acidic and can react with niacinamide to sting and irritate your skin. You can easily fix this by using them in separate morning and evening routines.

Questions and answers

Can you use niacinamide and citric acid together?

Using niacinamide and citric acid together depends on the strength. You can find both ingredients in NIVEA DERMA SKIN CLEAR.

Which goes first, niacinamide or citric acid?

You should avoid mixing niacinamide and strong acids like citric acid in the same routine, so use them at different times of day or separate them by at least 30 minutes. You can also use a finished product like NIVEA DERMA SKIN CLEAR.

Are niacinamide and citric acid good for sensitive skin?

Niacinamide and citric acid may not suit sensitive skin when used together, depending on the product strength. Strong acids like citric acid can lower the product's pH and cause flushing or irritation if combined with niacinamide in the same routine, though products like NIVEA DERMA SKIN CLEAR contain both.
