[This review was collected as part of a promotion.] Makes my pores greatly reduce. I would recommend only using once a day if you have sensitive skin though. If you have big pores like me though this is very necessary. Very smoothing. The price for the quality is also great. My holy grail!
Love It!!!

[This review was collected as part of a promotion.] This works great on my skin, niacinamide is my favorite ingredient. It curtails my acne and my oil production. It's very consistent in quality, every time I've got it it works just as expected, and it leaves my complexion looking and feeling nice. Definitely start slow until you stop feeling a tingle, so once or twice a week and build up. I use it every other night currently.

[This review was collected as part of a promotion.] I use this serum after I have washed my face with the Low PH Good Morning cleanser, and after I have toned my face with the AHA/BHA Clarifying Treatment Toner. Before, I didn't use a serum in my skincare routine, so this was new to me. The serum itself goes on my skin smoothly, and it is a good boost after my toner. It sets a nice base for my moisturizer after.
