It is a good price for the size of the product and it has a water-like texture, so I think it would be nice for very oily skin. Also it might be great for people who react good to niacinamide, since it is not a serum and might be better for layering skincare.
This product made me think that niacinamide does not work for my skin, since it did dry me out a bit and left my skin kind of waxy after I use it. Turns out I just tolerate niacinamide better in smaller concentrations and combined with other soothing ingredients.
