Two niacinamide products?

Two niacinamide based products is unnecessary tbh. I’d stick with the one you have and when it’s empty you can try one of the other ones, or find a product that has multiple ingredients with niacinamide in a powder strength if you’re looking to tackle other concerns.

The niacinamide 5% is enough. Just get the daily brightening serum. The Niacinamide toner may or may not give you any more benefit. it really depends on your skin tolerance. but honestly you dont want to be risking it if you dont need to

If you really wanted to incorporate a new niacinamide, you can always alternate them everyday ☺️

Actually I have some products that contain niacinamide, I just used all of them in a day. Like for the serum I used it at the night and for the essence I used it at the morning. I don't get any negative reaction maybe since they have low percentage niacinamide in it, I guess it's about 2% or something I bought the essence one because there has specific main ingredients that I really want to try so bad. I think it's okay if you have both products that contain niacinamide and try them as long the percentage not that high. If the main ingredients of them is niacinamide I don't think you need it. But every skin is different right. Always listen to your skin first

Hi! I personally recommend to simplify your skincare routine, since using too much products can cause higher chance of irritation. If you want recommendations, I personally recommend these and works great in all skin types!
