I am 44yrs. I’ve been using this product well over a year. It gives my skin a glassy glow & makes it soft to the touch! Makes my pores appear smaller too

  • Effective and affordable!
Size: 1 Fl Oz (Pack of 1)
This niacinamide serum is super affordable and actually works to moisturize and hydrate my skin. It helped smooth out my skin and fade some dark spots without any irritation. Lightweight, soaks in fast, and layers well. Can’t go wrong with this on

  • Good quality
Size: 1 Fl Oz (Pack of 1)
I haven’t ever tried niacinamide but I know it helps with skin texture issues. The ingredients are great! I’ve only used it once this morning so I will see if it helps with skin texture issues and dark spots! Not oily at all it absorbs fast. Update: after a month of using this religiously (on my second bottle) the pores on my face have reduced dramatically as well as frequency of breakouts. Also a dark spot on my forehead has lightened a lot. I’ll be using this forever! ... show more

  • Works wonders!
Size: 1 Fl Oz (Pack of 1)
This niacinamide serum has really improved my skin texture and tone. It helps reduce excess oil, minimizes the look of pores, and makes my skin feel smoother and brighter over time. It layers well under moisturizer without feeling sticky, and I’ve had no irritation at all. A simple but very effective addition to my skincare routine. ... show more
