Got it for my husband, he didn't get to try it yet. He has acne and deep pores, and judging from the reviews, I'm sure this'll work for him.

Amazing product. Cleared my cystic acne up right away. It's not sticky. I was pleasantly surprised by the consistency and how light it feels on your skin. Will definitely be purchasing once the bottle runs out.

This works great on my

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.

I use this serum after

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.
