I've been using the Innisfree My Real Squeeze masks for a long time now, and I decided to try these to see how the two compared. I got the BHA ones and ohhhhhhmygod, they're incredible. The first time I used it, I could actually see a difference in skin texture- my face looked visibly smoother when I took the mask off and let the remaining essence absorb. The only downside is that it's a bit hard to pull off the plastic sheet from the actual mask, but other than that this product is excellent. I've repurchased the BHA but I want to try the others to see how effective they are as well.
