    Love that it comes as a duo

    I use this niacinamide every day and love it! I only wish we could buy it in 100 mL like the hyaluronic acid.

    Like it

    To be honest, I'm not really sure what it does for my skin. I occasionally incorporate it into my routine because it's probably doing something? I like that it doesn't give me as many closed comedones like some other ones I've tried.
