20% Vitamine C + E Ferulinezuur Serum

I was hesitant about a 20% L-ascorbic acid formula, but it sinks in fast and I've had zero stinging so far, just a nice glow by week two. The lack of fragrance is a relief since most brightening serums smell like hot dog water.

The dropper makes it easy to get just the right amount, and the 20% L-ascorbic acid hasn't irritated my skin at all—just a slight tingle. I've been using it for three weeks and my dark spots are already visibly fading.

After two weeks of using this every morning, my dark spots from old breakouts are visibly lighter and my skin just looks brighter overall. I love that it's completely fragrance-free, since my face is sensitive to anything scented. It does tingle a bit on application, but that passes quickly.
