メンズ用リペアリングビタミンCフェイシャルセラム（旧ナイトセラム）

Three weeks in and the tightening effect is real—my jawline looks noticeably sharper. It sinks in fast without any greasy film, which matters when you're rubbing it on right before bed.

Three weeks in and the fine lines around my eyes are genuinely less noticeable, plus my skin feels tighter after my morning shave. I wasn't expecting a serum to calm the redness from my razor burn, but this stuff does the trick without any greasy residue.

I’ve been using this every night for about two weeks now, and the tightness I feel after applying is honestly a little addictive. The fine lines near my eyes haven't vanished, but they're definitely softer, which is more than I expected from a serum.
