It feels slippery on my skin, so it spreads nicely all over my face. Just 3 drops is enough for me. I feel like this really speeds up in reducing my hyperpygmentation. And because "a little goes a long way", it will lasts for a pretty long time.
I can use it as a toner.
I love how the packaging is super sturdy (aluminium based i think?), and it's the cap bottle type so really easy to use. The cap is also tight so i don't have to worry the product will spill.
1) It gave a tingling effect on my skin, especially where it's really sensitive (the corner of my nose). I dunno which ingredient causes this, because i never saw a reviews that experience this.
2) Kinda tricky to layer because of how reactive it is on my skin
3) The PAO is only 6 month
