I'm still not 100 percent sure on this one. If I could give it 3.5 lippies, I would. To be kind, I'm rounding up.
I have dark circles and some baggage under my eyes. This has caffeine and vitamin C, which are said in some circles to improve the undereye area's appearance, which appeals to me, for obvious reasons. Paired with the little metal roller ball, application feels cool for a second, which I hope helps reduce puffiness a tiny bit. If nothing else, it feels nice. I also was pulled in by the sheer tint. The light/medium works well on my light skin, at least in the undereye area. If this was a concealer for my forehead or something, it wouldn't work so well, but for an area that needs a blast of brightness, it's right on.
So far I like this. I'm in my 40s and have the aforementioned dark circles/bags, and I'm starting to see more lines around my eyes, along with a more crepe-y texture. It feels nice to use the roller to apply it, and it's not a thick, goopy formula, so it blends easily and seamlessly on me.
Update (Aug. 2017): I've tried this for a while now, maybe three or four days a week. I've used it when I wear glasses, when my trouble spots are less visible, or without, when I feel like a spotlight is on my undereye region. So far I'm still in the middle on this. I don't notice any improvement in dark circles, but when I do use it, it softens the undereye area's darkness. It does not mask them entirely, but it does blur and diminish them somewhat, and it doesn't ever seem to crease for me. That last one is a real relief because it's not a lovely surprise to find the equivalent of crepe paper under one's eyes at 2 in the afternoon.
So far I'm not noticing any major problems with it settling into lines, etc. I wouldn't say it's long lasting, but it's easy enough and liquidy enough to touch up. It does not erase my dark circles but it does buff them away somewhat and make them look a bit less prominent. (I know if I want a real, permanent fix, it's laser or surgery time for me.) But this does help, making me feel a bit less ghoulish, and I'd rather have the lighter coverage and less settling in lines than a heavier formula that just emphasizes trouble spots. I'm happy there's no real scent here, either, unlike some past incarnations of Garnier skin care.
I haven't used it long enough to say if it's making any long-term improvements, like less noticeable dark circles, but I'll enjoy using this and finding out.
