Sérum Cernes et Poches — 咖啡因5% + 菸鹼醯胺5%

I’ve been using this every morning for three weeks and the puffiness around my eyes is genuinely calmer by midday, even after short nights. The 5% caffeine concentration feels like it actually does something, and it layers nicely under moisturizer without stinging.

My under-eye area looks noticeably less puffy in the mornings now, and the niacinamide has helped smooth out the texture without any irritation. It sinks in fast and plays well under my concealer.

The 5% caffeine really shows—after a week of using it morning and night, my under-eye area looks less shadowed even when I've slept badly. It's a thin, watery texture that sinks in fast without any stickiness before my concealer.
