I've posted about similar patches before, and since then, I've tried a few brands to compare. They've all worked great for me in dealing with hormonal acne and the oh-so-lovely "maskne".

What I've really liked about this brand is how many patches are included in the pack- you get 140 patches in 4 different sizes, and it comes out to about $0.08* per patch (or $0.05 per patch if you get the 2-pack), compared to the similar leading brand that comes out to $0.36 per patch.

*Prices accurate at time of posting, but are subject to change
