Star3 qty Not for me
Tre...@ 15% Niacinamide, Acetyl Glucosamine, Zinc PCA, Allantoin Not too sure why CosRx went so hard on these percentages but man 15% was a little intense. This one didn’t suit my skin and caused some breakouts. I tried to target this on my t-zone only but it just didn’t work well for me. I think this might be better suited for oily-resilient skin. The serum is actually quite pleasant in texture, especially for something based on niacinamide. It is intended to exfoliate the skin & soothe acne.

Star5 qty
Nat...@ 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.

Star5 qty Helps with congestion and maskne
mar...@ 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!

Star4 qty Leaves a wierd residue
lin...@ 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.⁣
