控油精華液 — 杜鵑花酸10% + 竹子萃取

My face feels the difference after three weeks—the bamboo extract really calms the shine by midday, and that 10% azelaic acid has smoothed the rough patches on my chin without any stinging. It layers nicely under moisturizer, so it's become a permanent step in my morning routine.

The 10% azelaic acid is doing exactly what it says—my T-zone stays shine-free for most of the day, and the texture is visibly smoother after a month. The bamboo extract makes it feel lighter than other mattifying serums I've tried, which is a nice bonus.

Three weeks in and my forehead is noticeably less shiny by mid-afternoon, the azelaic acid clearly doing its job on the oil. The bamboo extract leaves a smooth, almost powdery finish that I can feel before I even apply moisturizer. It’s become the one step I won’t skip in my morning routine.
