COSNET 10% Niacinamide with 1% Zinc PCA Face Serum

I love that this has Sodium Hyaluronate. It gives me that oil control I need but my skin still feels plump and hydrated. It doesn’t have that 'tight' feeling some other acne serums give.

I did have a few small bumps in the first few days—my 'purging' phase—but I stuck with it. After 10 days, my skin cleared up completely and now it’s the clearest it’s ever been.

My face used to be an oil slick by midday, especially in this humidity. This serum keeps my skin matte without drying it out. I noticed a 50% reduction in greasiness within the first week.

I bought this because my pores on my nose and cheeks were looking huge and 'stretched.' After using this for about 4 weeks, the difference is visible. My skin texture looks much smoother, and those open pores seem to have tightened up. It gives that 'glass skin' effect after a month of consistent use.

I have struggled with a shiny 'grease-pan' face by 2 PM for years. This serum is the only thing that actually works to mattify my skin without drying it out. The Zinc PCA really balances the oil production. My skin looks semi-matte and fresh all day, which has made me much more confident in my zoom meetings.
