Amelia ★★★★★

My pores are noticeably smaller after just two weeks, and the 15% niacinamide doesn't irritate my skin at all—it's surprisingly gentle for such a strong formula.

Kevin D. ★★★★★

I've been using this for about three weeks now, and the 15% niacinamide formula really helps calm down my breakouts without drying my skin out. My pores look noticeably smaller around my nose area, which is a nice bonus.

David M. ★★★★★

After just a week of using this, the pores around my nose look noticeably smaller. It's a bit sticky at first, but it dries down nicely once I give it a minute.

Jacob ★★★★★

I’ve been dealing with stubborn blemishes for months, and this serum has really helped calm them down without drying out my skin. The 15% niacinamide formula feels lightweight and absorbs quickly. Definitely noticing smaller pores after a few weeks.

Alexander R. ★★★★★

My skin texture has noticeably improved since I started using this—those annoying bumps around my chin are finally smoothing out. The 15% niacinamide feels a bit strong at first, so I ease into it with just a few drops.

Sophia Y. ★★★★★

I’ve been using this serum for three weeks now and the 15% strength really helped refine my pores without any irritation. A little goes a long way and it layers nicely under my moisturizer. Definitely my new go-to for that glass-skin look.

Samuel ★★★★★

My skin is usually pretty reactive, but this 15% niacinamide formula didn't irritate at all—just visibly tightened my pores within a week. The texture is watery enough to soak in fast before my moisturizer.

Nicholas W. ★★★★★

I’ve been using this serum for two weeks now, and my skin feels noticeably smoother with fewer breakouts. The dropper makes it easy to apply just a few drops, and it absorbs quickly without any sticky residue.

Claire ★★★★★

After just two weeks, my pores look visibly smaller and my skin tone is way more even. I was worried about irritation with a 15% concentration, but it actually feels quite soothing.

Lily ★★★★★

This is the first serum that’s actually made my pores look smaller without irritating my skin. The 15% concentration feels potent but not sticky, and I noticed a real difference in my skin’s texture within a week.
