I really like this! I think it has done my skin well, from the timeframe of a month using this I do feel as though my skin is slightly brighter and acne is much less frequent. I can't even comment on fading dark spots and things like that because quite honestly I haven't had acne in a while that has had enough time and size to come to a head and create a noticeable acne scar. The acne scars I do have had sped up teency bit in disapearing but I don't think it's done that much for that. I have changed my skincare items as well in the timeframe but serum has definitely helped to some capacity. It also applies very nicely, the texture is watery (very slight goopiness) and when applying this my skin already starts absorbing it quickly. I like it better than other niacinamide serums that I've tried too. The size was a pleasant surprise to me, bigger than I expected and the packaging is very cute and aesthetically beautiful. It's sturdy and thick, with quality tinted glass for sun protection and the dropper screws in place very nicely. I'm pointing this out as I feel there are a lot of terrible dropper screws that screw terribly so I know that this is a good quality bottle. The box it came in also exceeded my aesthetic expectations and I felt a bit of a hesitation when I threw it away. I'm pleasantly impressed by everything this product has done for me!
