I have reviewed products in the past that are all over the place. If they weren't, they'd have been written about.
My goal is to put a few rules together. First, it has to be a cream or serum with an effective ingredient list. That means that it should work to reduce acne. The second rule is that it can be effective for at least 2 months, unless the ingredients are not effective. The last rule is that you need to find a good brand name, preferably one that you trust. If you're buying online, you might have to wait a month, but you're better off waiting. I've found that some brands have poor quality control or they get new brands and new ingredients a couple of weeks after they're in stock. These brands are not worth the time. My search strategy is to go to the website of the brand that I trust. How long does it take to find an acne cream that works? As of today, I've found 3 brands that I can recommend. These are: Innisfree Super Power Watery Toner Boscia Clear Toner Cetaphil Toner I'm not sure about the other two, but I don't feel like I'm wasting my time when I use one.
