ISNTREE - Ruby review for C-Niacin Toning Ampoule

The consistency is a winner for me. It is very lightweight like water that has slip to it. This is absorbed well by my skin without any tackiness. I don't detect any scent as well! Great to use for am and pm routine and you can actually layer other ampoules over it. It really helped me lighten my acne scars with consistent use! I didn't experience any bad reaction too.
