It has a light in texture making it very easily absorbed without greasy feeling and unscent.A nice serum that helps keep the skin hydrated when used under a moisturizer. I use this in the morning mix it with vitamin c and it really plumps up my skin. There's no distinct scent and I think it would work well on all skin types,including sensitive skin.

NIACINAMIDE 15 #AcneDermSerum Targeted towards acne care, sebum & oil control. Also provides exfoliating properties & smoothens the skin. Cosrx formulated this with the maximum concentration of 15% which I thought was not possible. From what I heard, we only need 5-10% of Niacinamide. I’m not complaining tho bc even with this conc, this did not cause any stinging or irritation. My previous one was 10% and would occasionally cause stinging & pilling. Happy that this serum layers and absorbs well. Even tho Niacinamide is known for it’s brightening benefits, I typically use Niacinamide to address congestion on my chin and prevent maskne. Hassle free application & my skin actually feels smoother. This is my fave out of these 3 serums!

I don't suffer with acne but I do have combo skin with an oily tzone which is what I mainly use niacin for. It has a toner like texture with a slippery slip feeling when you apply it. It dries down almost instantly so I find it applies better with a roller than my hands. It helps reduce the excess oil my skin produces but it leaves behind a residue I don't like so I've been using it at night.⁣

#yeppuji Experience

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!

This serum has a thinner consistency. It is clear in colour, has no scent and applies easily into the skin. I find this serum a bit more sticky/tacky for my skin making it feel heavy. This would benefit more if you have oily skin or acne.

This Niacinamide is very effective and beneficial for my aging skin! My skin is firmer and plumper. It is the most effective Niacinamide that I’ve tried

I can feel my skin is more brighten and less oiliness! Maybe is because it contains Niacinamide! "Niacinamide can help fade hyperpigmentation on the skin. Balances oil production!

This Niacinamide serum is pleasantly light with a bit of viscosity that applies and sinks into the skin easily and readily. The texture of this serum is much lighter and less dense than a lot of Niacinamide serums I’ve used in the past, resulting in less mess and a more enjoyable user experience. Due to the lighter texture of this serum, it pairs well with other serums without feeling like it overloads the skin and without exacerbating already oily skin. While using this serum, I noticed an overall improvement in oil production which is especially handy during the summer heat. I’m not sure if it’s mainly a result of the reduced oil production, but I did have fewer outbreaks while trying out this serum, and the acne I did get was noticeably less severe in size and redness compared to my typical outbreaks.
