Thinking back to my first JayJun mask requires a pretty sizeable trip down memory lane. In 2015, K-beauty products were hard to find locally, and hauling from Korea was a very real thing. I adore black masks, especially these, and love how travel friendly they are. The foaming cleanser has a fairly high pH, I suspect, based on how squeaky clean my skin feels when I'm done. Now, if this was my daily cleanser, that would be a problem. Considering this is meant to be a once-in-a-while thing, I'm absolutely fine with that one minor flaw. After all, I can toss this singular item into my overnight or carry-on bag and have an on-the-go treat without effort. Also, the cleanser is VERY concentrated, so you could probably get at least two uses out of the sachet. The gel-style essence works well, especially after the cleanser, and is the perfect segue to the sheet mask, which is a standout product for its fit, saturation, and ability to even out my skin tone in 20-30 minutes. As long as Jayjun keeps making these, I will keep buying them.
