I mixed this with The Ordinary Natural Moisturizing Factors + HA. Mixing it together was fun! If you use the correct amount it lasts a really long time and I’m not so worried about it goinf bad since it’s a powder.
I found this MUCH less irritating than The Ordinary Niacinamide 10% serum.
I like that this product gives me the option to add niacinamide to my existing routine, without also adding any other ingredients that might be lurking in a serum.
And it’s cheap!
I think that for some people the mixing process might become boring and annoying very quickly. The scoop they give you is also about 4x the recommended amount so you have to sort of guess how much a quarter of a scoop is. I put too much the first few times I used it which resulted in a grainy texture to my moisturiser. I dont know why they dont just include a smaller scoop, it’s such an easy fix.
I’m not sure if this product made any significant change to my skin. I would buy it again though to continue testing.
