ナイアシンアミド＋グリセリン配合 ブライトン＆グロウ ハイドレーティングプライマー

My skin drinks this up—the glycerin base feels like a cool splash of water right before foundation, and the niacinamide has genuinely evened out my dull spots after a few weeks of daily use. Makeup sits noticeably smoother over it, no patchy dry bits by midday.

I've been layering this under my makeup for two weeks now and the glycerin really locks in moisture all day, plus the niacinamide gives my skin that lit-from-within look without any shimmer. It's not heavy at all, just a nice smooth base that makes my tinted moisturizer glide on effortlessly.

My foundation used to settle into dry patches by midday, but this primer keeps that glow going for hours, and the niacinamide actually seems to calm my redness. The texture is like a light gel that disappears into skin—no tacky residue, just a soft radiance before I even add makeup.
