Pros
- Affordable
- Great packaging
- Hydrating formula
- Great ingredients for a good price
- Sits well under moisturizer and foundation
- No pilling

Cons
- Broke me out, however this was mitigated when using a HA hydrating toner as well (Hada Labo Goku-jyun).
- Did not reduce my redness and was a little irritating to my sensitive skin (I have used arbutin in the past - The Ordinary's formula was my HG)
- My face always looked tanned after this for some reason
- Oxidizes on your skin

Should you buy it?
Yes It's a great, easy to use and easy to incorporate serum for your routine if you are looking for arbutin and HA, and can't get The Ordinary's one (like, say, you live in Aus/NZ).

No If you have sensitive skin and are prone to skin reddening or darkening when it is hot. I used this in summer and found that my face had a more tanned appearance with it because it was mildly irritating to my skin. I did not have this reaction with the Good Molecules Discolouration serum which I feel is a much better formula.

I feel that even at this price point, there are better formulations out there such as The Ordinary's Arbutin.
