Glow-C Vitamin C 20% Serum

My skin looks noticeably brighter after three weeks, and the 20% concentration hasn't caused any redness like other serums have. Even on my oily days, it layers cleanly under moisturizer without that greasy feel.

The 20% concentration is strong but somehow doesn't sting my sensitive skin at all. After three weeks of nightly use, my dark spots from old breakouts are visibly lighter and my face has that lit-from-within look. Absorbs fast with zero greasy residue.

I've tried other vitamin C serums that left my face sticky and orange, but this one sinks in clean and doesn't irritate my sensitive skin. The 20% strength actually evened out my dark spots after about three weeks, and the glow is real—it's the only thing I've repurchased twice this year.
