It's my first time using a niacinamide serum with a high percentage, so I was a bit nervous. I patched tested for two days to ensure I wasn't getting any reactions. Surprisingly, I didn't get any, so I was safe to use it. I use the serum in my AM and PM routine to see its full effect. The serum looks and feels thick; however, it penetrates and absorbs quickly into the skin. As a result, my t-zone area where I have oils looks more balanced the next morning and throughout the day. It also does a great job of tightening my pores in the butterfly area and brightening my skin. I'm super please and looking forward to the results after I finish the bottle. I received this product for free from @cosrx and @stylekorean_global for an honest review.

This serum helps to minimise pores and sebum and control oil..Thid is perfect for summers..It has an oily texture and easily absorbs onto skin..

Niacinamide serum which is specifically for acne prone skin has a light texture and is easy to absorb. The feel is quite moisturizing on the skin but also has an oil control effect, so I'm comfortable using it in the morning and under makeup.

Niacinamide is one of my favorite actives. I’ve been using this daily, and plan to continue doing so. I love the texture and absorption of it. A lighter weight serum that absorbs quickly and doesn’t leave behind any tackiness. This contains the maximum amount of niancinamide (15%) as well as a bunch of other actives that work in tandum to help control acne, but not just that, I find these do a fantastic job of brightening, exfoliating, and controlling sebum for those that don’t have acne issues like me. I have combination skin and adding this serum along with their Hyaluronic Acid serum is the perfect combination. Bottom line this is a win for acne control, and reducing post acne scars, or just in general brightening your skin and keeping it healthy. If you have spots from aging, sun, you name it, this is a great serum to add to your roster

Niacinamide is an oily girl’s favorite ingredient especially since it is know to help with oil control. In addition to the main ingredient, this serum also contained Acetyl glucosamine a derivative of glucose, which a multipurpose antioxidant that helps gently exfoliate and helps with skin aging. This serum has a noticeable slip. It sinks in feeing tacky, but that tackiness disappeared after it dries. I enjoyed this serum especially during the summertime when my oils are out of control. A lot of products have Niacinamide like their HA serum so I would only buy this if I went for a minimal routine!
