Cos-IQ 20% Niacinamide Face Serum For Clear Glowing Skin, Bright Skin, Reduces Dullness, Hydrates & Repairs Skin with Vit B3 & Hyaluronic Acid for Targets Acne Marks | For Women & Men | 30ml

I’ve been using this COSIQ Vitamin B3–20% Face Serum for a couple of weeks now, and I’m honestly loving it. I was a little nervous about the 20% niacinamide at first, but it didn’t irritate my skin at all (which is a big win for me).My skin feels smoother, my pores look smaller, and the dark spots I had from old breakouts are already starting to fade. It also helps control oil, so I’m way less shiny by the end of the day.It’s got peptides and hyaluronic acid too, so it keeps my skin feeling plump and hydrated.it even helped calm down a few pimples.What I like:• Super smooth texture• Clears up skin and fades dark spots• Doesn’t dry me out or cause breakouts• Just overall makes my skin look healthierIf you’re thinking about trying it, go for it! Just maybe do a patch test if you’ve got really sensitive skin. I’m definitely going to keep this in my routine.

Budget friendly niacinamide serum. No strong fragrance. Good formulation.But absorption on my dry skin is poor. Forms a stick non absorbed layer on my face.
