I've wanted to try Alpha-Arbutin for a long time since i've read so many raved about this ingredient online. This is my first time trying a serum from this brand. I'm using this in my PM routine. It feels heavy on the skin and the texture is a little bit sticky. I used it for a while and so far no effect of brightening 😅 My skin doesn’t have any problems with acne scars so I won’t be able to provide any information on that part. Instead, I do have age spots and pigmentation and I was expecting to see some difference at least. Overall This serum is cheap which makes it possible for everybody to try it out
