I’ve been using this product for almost 3 weeks and I can definitely see a difference. It obviously takes time to see a noticeable change but overall i think I like it. One thing I would like to point out is that it leaves a clear white cast after you apply it on your skin. Also, I noticed my skin was more sensible during the day when I applied it in the morning so I wouldn’t recommend using this cream during the day if you have sensible skin. I’ve been using two other products that contain niacinamide as well, so I think I’ve experienced a change on my skin quicker than expected because of that. My goal is to eliminate dark spots and so far so good I guess.
