Sérum Rides et Fermeté — 植物膠原蛋白1% + 維生素C 10%

I’ve been using this serum for about three weeks now, and the texture is surprisingly light—it sinks in fast without any tackiness, which I love under my moisturizer. My skin definitely feels firmer around my jawline, and the vitamin C concentration is strong enough that I notice a subtle brightness

The 1% plant collagen and 10% vitamin C combo sinks in without any sticky residue, which I really appreciate before moisturizer. I'm two weeks in and the fine lines around my eyes look softer, plus my face has that lit-from-within glow.

My skin feels noticeably bouncier after three weeks of nightly use, and the 10% vitamin C hasn't caused any irritation like other serums have. The texture sinks in fast without that sticky morning residue, which is a huge win for a 1% collagen formula this concentrated.
