Trueskinbliss review for Niacinamide Serum

You never know how much product is (exactly) left because of the packaging. I know it sounds picky haha but the bottle itself is already heavy so you can't tell by the weight. At least it makes it more 'luxurious'. Also I have not noticed any remarkable achievement so far (keep you updated, only week 4 and niacimide need 6 weeks to develop your skin). Please note it's my first Niacimide and I don't know what to expect or if this was the right choice for my first time 🤷‍♀️
