I've been using Arnica anti-redness ample for a week now, and while I didn't notice immediate results (as in overnight), I did notice it leaving my skin in a overall better condition. After a few nights I noticed reduced redness. It's very watery and scent-free - you have to shake it well before use (you can see the difference in the photos before and after shaking). Overall, so far I'm very satisfied with the results.
