Serum Phức Hợp Vitamin C - Cỡ Lớn

The jumbo size is a lifesaver—three months in and the bottle’s still going strong, which is rare for a vitamin C serum that stays stable. That stabilized l-ascorbic acid hasn’t oxidized or turned yellow on me at all, and my skin looks brighter without any irritation. Gold’s a nice touch too, though

I've been using this for two weeks now and the stabilized l-ascorbic acid hasn't irritated my skin at all, which is rare for me. The gold in the formula gives it a nice subtle glow right after application, and the jumbo bottle means I don't have to ration it like my old one.

The jumbo size is a solid money-saver, and I’m almost through my first bottle—my skin looks noticeably brighter, especially around my cheeks. The gold in the formula doesn’t feel gimmicky; it blends in smoothly and leaves no residue.
