It's amazing. It's my HG serum when it comes to help my skin with hydration and moisture so far.
It has a dewy finish. I use around 6-8 dots for my face and neck, then I use a moisturizer on top. I have a gel moisturizer (anua soothing cream 70%) that isn't moisturizing enough, but with this, the very noticeable shine lasts max. 8 hours from night to morning (when I wake up), considering I don't usually wait 1 hour after doing my skincare before going to sleep. I wake up with softer skin as well. Even by afternoon though, when I skip using it in the AM, my skin is still slightly dewy (just not as noticeable), and softer than before.
So: it has helped me get a glass-skin shine when putting it on, and once the 8-hours pass and I don't put it on the AM, I still have a more natural shine which people with normal skin have, like some friends. I have a lot of dullness and my olive skin looks gray sometimes— especially on my cheeks, so this is really helpful.
I recommed it if you have dry or dehydrated skin. It is a bit sticky at first, so you can use it on slightly damp skin if it annoys you. Personally, I don't really mind, but I believe using it on damp skin helps with hydration as well (because the only thing that hydrates is water).
It can also be used in the morning, and the shine will last more time if you use a more occlusive product on top, which I recommend.
Only con is that it stings eyes a bit, but that's most products for me, because my skin is reactive and my eyes are very sensitive.
Overall, it's my favorite. I don't think I'll stop using it soon. Another plus is that it's a bottle of around 50ml, and you only need to use a bit, so it lasts a long time, around 1.5 months if you use it twice daily, and around 3 months if you use it once daily. I see most serums are 10ml-30ml, so this one is truly worth it.
Edit: I forgot to mention the smell. The smell fades away when you start putting it on after some seconds, and isn't strong to the point I would think it is fragance-free if it smelled more clinical, or like glue. I don't know how to describe the smell— perhaps slightly like flowers, but it's really light so not as noticeable. I have a sensitive nose and I don't like using perfumes usually, but this products works for me because of how light the smell is.

Good do-it-all serum for lazy people
I love this because I'm super lazy with my skincare.
I find this serum to be extremely moisturising without being too heavy and so, I use this as my last step in my night routine (without any other moisturiser)
On my laziest day's i'll just cleanse my face and slap this on.
