Yes, niacinamide and azelaic acid can be used together. Niacinamide is a form of vitamin B3 that can help reduce the appearance of enlarged pores and improve uneven skin tone and texture. Azelaic acid is an antibacterial and anti-inflammatory ingredient that is effective against acne-causing bacteria and can reduce redness and inflammation. When used together, these two ingredients can be beneficial for a variety of skin concerns.

Should I use niacinamide or azelaic acid first?

It depends on your skin type and the condition you’re trying to treat. Generally, niacinamide is more suitable for oily skin, and is best used for treating acne and hyperpigmentation, while azelaic acid is better for dry skin, and is best for treating rosacea. It’s best to consult with a dermatologist to get a personalized recommendation based on your skin type and condition.

What should you not mix with azelaic acid?

Azelaic acid is a powerful ingredient for treating skin conditions such as acne, rosacea, and hyperpigmentation. However, it should not be mixed with other active ingredients, as this can cause skin irritation and other adverse reactions. When using azelaic acid, it is important to ensure that it is the only active ingredient in your skin care routine and that it is not mixed with other products.
